Page 41: Setting The Horizontal And Vertical Axes
The timing can also be controlled by a clock signal applied externally. External clock signals are input through the external clock input terminal on the left panel facing the DL750/DL750P. This external clock input is useful for observing a signal whose period varies or for observing waveforms by synchronizing to the clock signal of the signal being measured.
Page 42 If you change the time axis setting, the sample rate (the maximum sample rate varies depending on the module) changes. The DL750/DL750P can only display waveforms correctly up to one-half the frequency of the sample rate (the number of samples per second, unit is S/s) as defined by the Nyquist sampling theorem.
Page 43 1 div = 0.500 V Measurement Range and Display Range The measurement range of the DL750/DL750P is ±10 divisions (20 divisions of absolute width (span) around 0 V. The display range of the screen is ±5 divisions (10 divisions of span). The following functions can be used to move the displayed waveform and display the waveform outside the display range by expanding/reducing the displayed waveform.
Page 44 2.2 Setting the Horizontal and Vertical Axes Moving the Vertical Position of Waveforms <Section 5.4> Since the DL750/DL750P can display the input waveforms of the analog input channels (CH1 to CH16), DSP channels (DSP1 to DSP6, optional), and computation channels (Math1 to Math8), the waveforms may overlap making them difficult to be observed.
Page 45 2.2 Setting the Horizontal and Vertical Axes Zooming in or out of the Vertical Axis (Expand/Reduce) <Sections 5.8 and 5.9> Zooming in or out by Setting the Magnification The waveform display can be expanded/reduced vertically by a factor in the range ×0.1 to ×100 (×0.25 to ×100 for 50 V/div, ×0.5 to ×100 for 100 V/div, ×1 to ×100 for 200 V/div on the 701260 (HV (with RMS));...
Page 46 2.2 Setting the Horizontal and Vertical Axes Input Coupling <Section 5.5> If you wish to observe just the amplitude of an AC signal, it is best to remove the DC component from the input signal. On the other hand, there are times when you wish to check the ground level or observe the entire input signal (both the DC and AC components).
Page 47 • Expands the voltage range that can be measured by the DL750/DL750P. When using a probe, the attenuation or current-to-voltage conversion ratio setting on the module must be set equal to the probe attenuation on the DL750/DL750P so that the measured voltage can be read directly.
Page 48 2.2 Setting the Horizontal and Vertical Axes Linear Scaling <Section 5.11> When measuring the voltage (current), strain, or frequency (number of Rotations/period/ duty cycle/power supply frequency/pulse width/pulse integration/velocity) on the frequency module, there are two methods of linear scaling: “AX+B” and “P1-P2.” AX+B The results obtained from the following computation based on the specified scaling coefficient A and offset B are displayed as cursor measurement values and automated...
Page 49 2.2 Setting the Horizontal and Vertical Axes Pulse/Rotate Function <Section 5.14> When the time base is set to external clock, one data sample is captured to the acquisition memory when one pulse of the external clock signal is input. You can specify the number of pulses of the external signal (in other words, the number of data samples captured in the acquisition memory) that will correspond to one mechanical rotation (one cycle).
Page 50 2.2 Setting the Horizontal and Vertical Axes RMS Measurement <Section 5.15> If the module of the selected channel is a High-Voltage 100 kS/s, 16-Bit Isolation Module (with RMS), the rms value of the input signal can be observed. AC-RMS This setting is used when you want to observe only the rms values of the AC signal, eliminating the DC components from the input signal.
Page 51 • You can turn ON/OFF the internal RJC circuit on the DL750/DL750P. ON: Use this setting to enable the reference junction compensation by the internal RJC circuit.
Page 52 Gauge Factor (K) when mV/V Is Selected K = 2 You can set the gauge factor to an arbitrary value on the DL750/DL750P. However, if there are no specifications on the strain gauge transducer, set K to 2. If K is not 2, e is derived within the DL750/DL750P using the following equation.
Page 53 2.2 Setting the Horizontal and Vertical Axes Acceleration Measurement <Section 5.18> The Acceleration Module (with AAF) (701275 (ACCL/VOLT)) measures acceleration using the output signal from the acceleration sensor. Direction connection is possible to a built-in amplifier type acceleration sensor. (Direct connection is not possible to a charge output type acceleration sensor that does not have a built-in amplifier.
Page 54 2.2 Setting the Horizontal and Vertical Axes Frequency (Number of Rotations, Period, Duty Cycle, Power Supply Frequency, Pulse Width, Pulse Integration, and Velocity) Measurement <Section 5.19> The Frequency Module (701280 (FREQ)) measures frequency, number of rotations, period, duty cycle, power supply frequency, pulse width, pulse integration, and velocity. •...
Page 55 2.2 Setting the Horizontal and Vertical Axes • Deceleration Prediction The deceleration curve is computed according to the following equation using the elapsed time after the pulse input stops (∆t). Frequency (f) = 1/elapsed time (∆t) The deceleration prediction starts after a pulse period (T) of the pulse one period before the pulse input stopped elapses after the pulse input stopped.

Page 64 2.3 Setting the Trigger • Wave Window Trigger This trigger is used to monitor the power supply waveform. It detects abnormalities in the power supply (disruption, sag, serge, frequency fluctuation, voltage drop, etc.). A reference waveform (realtime template) is created by setting a tolerance (window width) to a waveform derived by averaging 1 to 4 cycles of waveforms before a cycle the current waveform.
Page 65 2.3 Setting the Trigger Trigger Mode <Section 6.1> Sets the conditions for updating the displayed waveforms. The following six trigger modes are available. Auto Mode If a trigger occurs within a specified amount of time (approximately 50 ms, referred to as the timeout period), the displayed waveforms are updated.
Page 66 2.3 Setting the Trigger Trigger Delay <Section 6.3> Normally, the waveform around the trigger point is displayed. However, by setting a trigger delay, you can display the waveform that is acquired a specified time after the trigger point. The selectable range of trigger delay is 0 to 10 s. T (Trigger position) Delay Trigger point...
Page 67 2.3 Setting the Trigger Trigger Hysteresis <Sections 6.5 to 6.16> If noise is present in the trigger source and there is insufficient trigger level width, the trigger point fluctuates each time a trigger is activated. This causes the displayed waveforms to be unstable. To solve this problem, a specified margin (hysteresis) is added to the trigger level.

Page 69: Setting Waveform Acquisition Conditions And Display Conditions
The sample rate and record length vary depending on the time axis setting. The DL750/DL750P allows you to select the record length from the following: 1 kW, 2.5 kW, 5 kW, 10 kW, 25 kW, 50 kW, 100 kW, 250 kW, 500 kW, 1 MW, 2.5 MW, 5 MW, 10 MW, 25 MW, 50 MW, 100 MW, 250 MW,...
Page 70 2.4 Setting Waveform Acquisition Conditions and Display Conditions Envelope Mode In normal mode and averaging mode, the sample rate (the number of times data is acquired per second in the acquisition memory) drops if T/div is increased. (See Appendix 1 “Relationship between the Time Axis Setting, Sample Rate and Record Length.”) However, in the envelope mode, the maximum and minimum values are determined at every time interval from the data sampled at the maximum sample rate of each input...
Page 71 Record No. = –99) History Memory Function <Section 11.1> If the record length is set short on the DL750/DL750P, the memory is divided into blocks, and waveform data is saved to the individual blocks each time a trigger occurs. If N represents the maximum number of blocks determined by the record length, the oldest waveform data block is cleared when the number of activated triggers exceeds N.
Page 72 2.4 Setting Waveform Acquisition Conditions and Display Conditions Dual Capture Function <Section 7.6> This function enables waveform acquisition in low-speed roll mode (main waveform) along with high-speed waveforms (sub waveform) using a different sampling interval. It is useful when capturing at high speeds abnormal phenomenon that occurs suddenly during long-term observation (low-speed sampling).
Page 73 2.4 Setting Waveform Acquisition Conditions and Display Conditions Realtime Recording to the Internal Hard Disk (Option) <Section 7.7> The data can be recorded in realtime to the internal hard disk (option). The stored data can be recalled. The realtime recording area is allocated on the internal hard disk in advance (the default value is 50% of the entire capacity of the internal hard disk).
Page 74 Voice memos are backed up by the backup function of the acquisition memory. Backing Up the Acquisition Memory <Section 7.10> If the ACQ MEMORY BACKUP switch on the right side panel of the DL750/DL750P is turned ON, the history memory data in the acquisition memory, the sub window data of the dual capture function, and the voice memo data are backed up even if the power supply is cut off.

Page 85: Waveform Computation
Waveform Computation Various computations can be performed on up to 800 kW of data on the DL750/DL750P. (If a waveform greater than 800 kW is displayed, computation cannot be performed over all the data at once.) The computed results become Math1 to Math8 waveforms.
Page 86 2.6 Waveform Computation Exponential Window The exponential window eliminates noise components from the signal. It can be selected only when the user-defined computation option is installed. It is effective against frequency response test signals generated through impulse excitation. For details on each window, see page app-21. FFT is performed on 1000, 2000, 5000, 10000, 20000, 50000 or 100000 points of measured data.
Page 87 Displays the maximum value of each point Scaling of Computed Waveforms <Chapter 10> The DL750/DL750P normally performs auto scaling when displaying computed waveforms. However, you can also select manual scaling. When auto scaling, the upper and lower limits suitable for displaying the waveform are determined from the first computed waveform and other parameters.

Page 727: Appendix 10 Basic Defining Equation Of Strain
ε = e in equation (6), ε = (4/K)×(V/E) In the case of a strain gauge sensor, set the Gauge Factor (K) to 2 on the DL750/ DL750P. If you change the value of K, conversion is made using the above equation.
Page 728: Appendix 11 Shunt Calibration Of The Strain Module
The Strain Module (701271(STRAIN_DSUB) supports shunt calibration and contains a built-in relay circuit for shunt calibration. To execute shunt calibration, a bridge head that supports shunt calibration (701957/ 701958) is needed. Measurement instrument (example: DL750) Bridge Head 701957/701958 (with shunt cal support) Sense+ Module...
Page 729 Mode. In normal shunt calibration, only P2:Y is set. In addition to the normal shunt calibration (when the shunt calibration relay circuit is ON), the DL750/DL750P allows the setting of a zero point when the relay circuit is OFF. This function is useful when the strain value is not 0 after the execution of balancing.
Page 730 Note • When executing shunt calibration, select an appropriate range so that the measured values do not exceed the range when the shunt calibration relay circuit is ON. The DL750/ DL750P attempts shunt calibration within the current specified range. •...

Page 733: Appendix 12 Measurement Principles (Measurement Method And Update Rate) Of The Frequency Module
Period (t) is the average value of multiple pulses. The frequency (f) is calculated as 1/period (t). If the input pulse period is short, the DL750/DL750P automatically takes the average of multiple pulses and calculates the period and frequency. Therefore, the resolution does not degrade even when the input pulse period is short, and highly accurate measurement is possible.
Page 734 Appendix 12 Measurement Principles (Measurement Method and Update Rate) of the Frequency Module Pulse Width and Duty Cycle Measurement • When the input signal is less than or equal to 25 kHz, measurement is made as described in (1). • When the input signal is greater than or equal to 25 kHz, measurement is made from the last waveform in the measurement interval as described in (2).

Range value Offset value Value/Div Internally, all calculations are performed using Floating 2400 LSB/div floating-point.
Page 736 The smoothing filter is a moving average filter in which computation is performed in realtime. The computation interval of moving average is 40 µs (25 kHz). It is constant independent of the sampling rate of the DL750/DL750P. The moving average order (the number of points of moving average) is specified in time.
