    CHAPTER 2 PRODUCT FEATURES The Megohmmeter Models 5050 and 5060 are portable instruments, housed in rugged casing. These megohmmeters are designed to check the safety of electrical installations and equipment. Measures: • Voltage • Insulation Resistance • Capacitance • Leakage Current Advantages: • Automatic voltage detection in all functions, before or during the mea- surement, which inhibits or stops the measurement.

    V/TIME - When measuring insulation, pressing this button displays the time elapsed since the beginning of the measurement, then the exact voltage generated. When performing resistance or capacitance measure- ment, this button has no effect. In MR (memory recall), it displays the date and time at which the measurement was stored, the exact test voltage and the OBJ : TEST number. • - Activates or deactivates the “time-controlled” test mode. • - Turns the display backlight ON or OFF. • ALARM - Activates or deactivates the alarms programmed in SET-UP. • - Selects a parameter to be modified. • SMOOTH - Stops/starts smoothing of displayed values during insulation testing.

    > 4 Excellent *The 10 and 1 minute times can be modified in the SET-UP menu, to adapt to any changes or specific applications. For multi-layer insulation, if one of the layers is defective, but all the others show strong resistance, the calculation of the PI and PAR ratios is not sufficient to show this type of problem. Therefore, it is necessary to supplement the PI and DAR indications by a dielectric discharge test (DD). This test measures the dielectric absorption of heterogeneous or multi-layer insu- lation while ignoring the parallel-surface leak currents. It consists of applying a test voltage for a period sufficient to electrically “charge” the insulation to be measured (a typical value is the application of a 500V voltage for 30 minutes).

  • Page 15 NOTE: During the measurement, the DAR value is not available if the DD value was preselected before the measurement. The PI value is not available if DAR or DD values were preselected before the measurement. Megohmmeter Models 5050/5060 0.561.8187 information@itm.
  • Page 16 DAR: Press START - the DAR symbol flashes and the display indicates “- - - -” as long as the calculation of the ratio is not possible (t <1 mn). e.g.: After 1 min, the measurement stops and the main display automatically shows the DAR value. During or after measurement, the R-DAR-PI-DD button can be used to see the insulation measurement carried out, but it does not give the PI value since the measurement has not lasted long enough. b) PI: Press START - the PI symbol flashes and the display indicates “- - - -” as long as the calculation of the ratio is not possible (t < programmed PI times). e.g.: After the upper PI time has passed, the measurement stops and the main display automatically shows the PI value. During and after measurement, the R-DAR- PI-DD button makes it possible to display the DAR (after 1 min), the PI and the insulation measurement. c) DD: Press START - the DD symbol flashes and the display indicates “- - - -” as long as the calculation of the ratio is not possible (t <30 min +1 min). e.g.: 1 minute after the measurement stops, the DD symbol becomes steady, the dis- play automatically show the value of DD.

  • Page 17 The time between each saved sample is programmed in the SET-UP menu. This function is also available on the Model 5050, which has neither a read-write memory for saving measured data, nor an interface for data retrieval from the instrument by a PC. Model 5050: Up to 20 samples can be recorded during measurement at the sample rate chosen in SET-UP (the default value is 30 seconds). It is possible to save more than 20 samples depending on available memory. Model 5060: The number of samples that can be saved is only limited by the memory space available. To enter the display mode, press the R(t) button: • The small display indicates the time 00:30 (e.g. the sampling frequency is every 30s). • The main display shows the corresponding R value.

    ACTIVATING THE ALARM INDICATION BEFORE A TEST To activate the Alarm Indication before performing a test you must go through the following steps: • Program the Alarm Set Point Resistance Value for the Test Voltage you will be using. • Turn the Rotary switch to the Setup position. • Press the Yellow 2 button and then the Alarm button to set Alarms. The first time you press 2 & Alarm you will see the alarm setting for 50 volt tests. • Press 2 & Alarm buttons repeatedly until you see the test you wish to set alarms for in the top line of the display. The sequencing will be 500, 1000, 2500, 5000, and set. • Use the cursor keys to adjust the Blinking value. First select KΩ, MΩ, GΩ or TΩ using the Up Arrow Key (). • Next, press the Right Arrow Key () to move to the next selection which is the greater than (>) / less than (<) choice. Use the Up Arrow Key to make your selection. Megohmmeter Models 5050/5060 0.561.8187 information@itm. www. .com...

    Selects the desired parameter to be modified - the selected parameter flashes. The flashing parameter is modified using the button (see § 2.5.6). Second Function - SMOOTH Activates a digital filter for insulation measurement. It only has an effect on the displayed values (which are smoothed) and not the actual measurements. For example, this function is useful when the displayed insulation values are highly unstable, brought about due to a capacitive component in the tested element. 2.5.6 Button Changes the flashing parameters displayed, or views R(t) values (see § 2.5.3). As a general rule, two figures (day, month, hour, min., sec., and OBJ:TEST) flash. The  and  functions have a “follow-on” mode. (e.g. as soon as the high or low program limit is reached, the parameter to be modified switches automatically to the following low or high limit.)

Press the MEM button for 2s (the display shows “MEM ALL FrEE”). Mea- surements are now ready to be saved. First Function - MEM (Save) Results can be recorded in the instrument’s memory and stored along with addresses defined by an object number (OBJ) and a test number (TEST). An object represents a ‘box’ into which we can place 99 tests. Thus, an object can represent a machine or an installation upon which a certain number of measure- ments (insulation, resistance and continuity) are carried out.
