  • Page 12: Installation Hints For Best Performance

    Installation hints for best performance This section offers several suggestions which will help you get the best performance from your weighing system. Loadcells create very small signals which can easily be corrupted by electrical noise. These steps will ensure you get the best possible performance from your meter. Use good quality screened signal cable, with 3 twisted pairs.

  • Page 17: Display Calibration Modes

    Meter Calibration Modes You can choose from two main calibration methods. 1. Direct Calibration - this is when you connect the meter to your system and make the meter read what you want it to, at 2 different points. This is the preferred calibration method, because it allows you to calibrate the system as a whole.

  • Page 18: Direct Calibration

    Direct Calibration - Full Scale Setting This is when you connect the meter to your system and make the meter read what you want it to, at 2 different points. This is the preferred calibration method, because it allows you to calibrate the system as a whole. How to do direct calibration:- If you have not done so before, please select Direct Calibration mode from the previous page.

  • Page 20: Linearisation With Direct Calibration

    Linearisation with Direct Calibration If your system is non linear, you can calibrate the meter and correct for this with the lineariser function. You will need to apply a series of known loads, starting at 0 and working up to full scale. You will then tell the meter what it should read for each applied load.
  • Page 21 Linearisation with Direct Calibration - cont’d. Set1 Set2 Output Alarms The display will show SE.01 Digit Apply your 1st known load to the system Max/Min Reset and press OK. The display will now show rd 01 You can now tell the meter what it should display for this load.
  • Page 22 Theoretical Cal. - Decimal Point & Full Scale This is when you type in the sensor’s theoretical signal level at the top and bottom of its range and the value to display, for each signal level. If you have not done so before, please select Theoretical Calibration mode from the Meter Calibration page AND choose whether your input is current or voltage.

  • Page 23: Theoretical Calibration

    Theoretical Calibration - Low end calibration This is when you type in the sensor’s theoretical signal level at the top and bottom of its range and the value to display, for each signal level. If you have not done so before, please select Theoretical Calibration mode from the Meter Calibration page.

  • Page 24: Linearisation With Theoretical Calibration

    Linearisation with Theoretical Cal. If your system is non linear, you can calibrate the meter and correct for this with the lineariser function. With this method, you can enter theoretical values for input signal and display values, with- out having to connect a sensor. First, you must select Theoretical Calibration Mode (see page on calibration Modes) Then, proceed as shown below...
  • Page 25 Linearisation with Theoretical Cal. - cont’d. Set1 Set2 Output Alarms The display will show In 01 followed by Digit an editing screen. Here you can enter your Max/Min Reset next calibration input signal level using DIGIT button to select each digit in turn. Increase or decrease the value of each digit using the UP or DOWN buttons.

  • Page 26: Sensor Drift Correction

    Sensor Drift correction If your system is normally reading 0, for example as is typical with platform scales or a torque meter, you may find a small amount of sensor drift caused by changes in temperature, ageing etc. We can automatically correct for slow, long term drift, by comparing your signal to 0 every 30 seconds, and re-calibrating to remove any detected movement.

  • Page 27: Logic Input Functions

    Logic input functions The three contact closure inputs on the rear of the meter have default functions which are:- Contact closure 1 = Tare Contact closure 2 = Peak/Valley display Contact closure 3 = Reset You can re-assign these to include :HOLD, Nett/Gross value display, Memory page address 1,2 or 4 (only if Multi-memory MEM option is installed) !! This feature is available in Advanced Mode only !! Lockout Switch must be OFF...

  • Page 28: Logic Input Connections & Front Buttons

    Logic input connections and front buttons The previous page explained how to select the functions of the 3 logic inputs. You can connect remote contact closures or open NPN collectors to activate these logic inputs. The logic input provides a 5V DC signal. When you connect this to common, a current of 1mA will flow.

  • Page 29: Factory Defaults

    Factory Defaults You can return the display to its factory default conditions whenever you wish. If you do so, you will permanently loose all your settings and will need to start from the beginning again. The calibration Audit Counter will NOT be reset, there is no way provided to reset this value, as it is intended as a secure record to indicate whether changes have been made to the display since it was last calibrated..

  • Page 30: Signal Filtering / Averaging (See Also Page 44)

    Signal Filtering / Averaging You can adjust the filtering time constant to reduce the effect of noise or instability on your input signal. A larger FIL value will give a more stable display, but the response to signal changes will be slower.
  • Page 31 Filter Jump value See the Easy/Advanced mode selection page near the beginning of this manual, and choose advanced mode. The Filter Jump value allows you to decide how the display will respond to a process step change. It does this by overriding the filtering, if the input signal moves by more than a chosen amount in one conversion.

  • Page 32: Last Digit Rounding

    Last Digit rounding up by 1, 2, 5, 10, 20 or 50 You can adjust the way the display rounds up, which is useful if you want to display a very large number, but do not want jitter on the last digit. The display can be set to round up to the nearest 1 (no rounding) 2, 5, 10, 20 or 50 This feature is available in Easy and Advanced Modes Set1...

  • Page 33: Scale Factor Adjustment

    Scale Factor adjustment After you have calibrated your meter, you can use the SCALE feature to make fine adjust- ments to calibration, without affecting the calibration itself. Examples 1.Changing weight units of measure from kg to pounds You could also use the SCALE to convert your readout from kg to pounds, without affecting the calibration.

  • Page 34: Offset Adjustment

    Offset adjustment After you have calibrated your meter, you can use the OFFSET feature to make fine addi- tions or subtractions to the reading, without affecting the calibration itself. For example if your weighing structure is altered after calibration and you want to subtract the effect of 37kg of extra metalwork which was welded to the hopper, you can easily do this by entering a value of -37 in the offset value.

  • Page 35: Menu Timeout Adjustment

    Menu timeout adjustment The display has a default timeout of 60 seconds, to allow you sufficient time to refer to the manual between key operations. You can make this period shorter, if you wish, once you become more familiar with the setup method.

  • Page 36: Reverse / Mirror Display Setting

    Reverse Display function (mirror image) If you need to be able to see a reflection of the display in a mirror or other reflective surface, for example in a simple heads-up system, or for drivers reversing into a bay, using mirrors only, you can set the display to show as a mirror image.

  • Page 37: Bootup Routine Choices

    Bootup routine and Tare save choices When you switch on your meter, it can be set to power up with 3 possible summary mes- sage combinations. The choices are:- bt 0 Segment test, followed by a full summary of software revision, calibration audit number, model number, installed options.

  • Page 38: Multi Memory Mem Option

    Multi-Program Memory option MEM The three contact closure inputs on the rear of the meter may be used to call up between 1 to 7 additional meter setup memories (pages), if the MEM option has been installed. This allows you to save up to 8 complete sets of independent calibrations, alarm settings, ana- logue output settings and serial comms settings.

  • Page 44: Input Board Filter Configuration

    Input board filter configuration The new input board now offers a sharp cutoff active filter which rejects all vibrations above 7 Hz. This is idea in applications where mixing or vibration is common. For optimum rejection of noise, we recommend you set the Fil.J parameter to 99 and choose a value for FIL which offers adequate filtering.
