Frequently Asked Questions - TV 431 Testboy

How to measure DC voltage with the TV 431?

Set the rotary switch to —V. Connect the test leads to the COM and V jacks. Attach the test probes to the voltage source. Read the value on the display. The measurement range is 0.1 V to 1000 V with an accuracy of ±0.5% + 5 digits.

How to use the Hold function?

Press the HOLD button to freeze the displayed value. Press again to release the value. The HOLD symbol appears on the display when the function is active.

What is the procedure for an insulation test?

Ensure the circuit is de-energized. Set the rotary switch to INSULATION. Select the output voltage (250, 500, 1000, or 2500 V) with the TEST.V button. Connect the leads to the HI and LO jacks. Press the Test button to start the measurement. The TEST symbol flashes. Release the button to stop; the device automatically discharges (display shows DISC).
Warning: Never perform an insulation test on a live circuit.

How to replace the batteries?

Set the rotary switch to OFF and remove the test leads. Unscrew the battery compartment cover. Replace the 6 C batteries (LR14) observing polarity. Replace the cover and screw it back on. Replace the batteries as soon as the low battery icon appears to avoid erroneous measurements.

What does the 'LIVE' display mean during an insulation test?

The LIVE display indicates that the device has detected a voltage greater than 20 V on the input jacks. This means the circuit is live and no insulation measurement can be performed. De-energize the circuit before proceeding.

How to activate the timer function for insulation testing?

Press the TIMER button to activate the timer (the TIMER symbol appears). Then press SELECT to display the preset duration, then press ENTER to modify it. Use the ▲/▼ buttons to set the duration (in minutes:seconds). Press ENTER to confirm. The insulation test stops automatically at the end of the set time.

How to save measurement data?

Press the MEMO button. The hold function activates automatically and MEMO appears. Use the ▲/▼ buttons to select a memory code (00 to 19), then press ENTER to save. SAVE appears and a beep confirms the recording.

What is the meaning of the DAR and PI symbols?

DAR (Dielectric Absorption Ratio) is the ratio of the resistance measured at 60 seconds to that at 15 seconds. PI (Polarization Index) is the ratio of the resistance at 10 minutes to that at 1 minute. These indices help evaluate the condition of the insulation. They are displayed after an insulation test by pressing SELECT.

How to disable auto power off?

Press and hold the SELECT button while turning the rotary switch from OFF to another position. The display shows PoFF to confirm. Auto power off is disabled until the next time the device is turned off.

What safety precautions should be taken before a resistance measurement?

Before measuring resistance or continuity, disconnect the circuit power and discharge all high-voltage capacitors. Use test leads in good condition. Do not exceed the rated voltages (CAT III 1000V). Wear appropriate protective equipment if necessary.

Warning

Comply with the following instructions to avoid an electric shock or injury.

• Only use the test instrument in accordance with the specifications of these instructions, otherwise it is not possible to ensure safe operation of the instrument.
• Do not use the test instrument or the test leads if they present visible damage or if the device does not function correctly. If in doubt, send the unit for maintenance.
• Before connecting the test instrument to the circuit to be tested, always ensure that the correct connection, switch position and measurement range is used.
• Check the function of the test instrument by measuring a known voltage.
• Do not apply a voltage between the connections or between the connection and ground which is higher than the nominal voltage stated on the test instrument.
  Exercise especial caution with voltages of over 30 V AC effective voltage, 42 V AC peak voltage or 60 V DC voltage, as these voltage values could result in an electric shock.
• Replace the batteries as soon as a low charge status is displayed.
• Disconnect the power supply and discharge all high-voltage capacitors before measuring the resistance, continuity or capacity.
  ● Never use the test instrument in proximity to explosive gases or steams.
  ● When using the test leads, ensure that you keep your fingers behind the finger protector.

Comparison function

If the comparison function has been activated and the measured value exceeds or undercuts the upper or lower limit value, a signal tone sounds and the text 'PASS' is not shown on the display.

The comparison function can be activated with 'COMP'; the display shows 'COMP'. If the pre-set upper limit value is smaller than the lower limit value, the comparison function is invalid; '-' is displayed.

Press the COMP button to show the upper and lower limit values. The display shows 'COMP' and the auxiliary display shows either 'HI' or 'LO' (see below): If the upper or lower limit value is shown on the display, you can change the value by pressing the ENTER button. The limit value displayed begins to flash. Use the SELECT button to select the correct measurement range. Set the desired value with the / buttons and save the setting with ENTER.

Time function

The time function is only available during the insulation test. Press the TIMER button to activate the time function (the display shows TIMER). The function with which to lock the Test button is not available when the time function has been activated. The insulation test is performed as soon as the MEASURE button has been actuated. The test comes to an end after a pre-set time frame.

The following display is shown in the time function mode. The current voltage and the time are shown on the auxiliary display. The test voltage is displayed whilst an insulation test is being carried out. Press the button to display the time.

The highest, lowest and average value

When working in test mode, you can display the highest, lowest and average value using the SELECT button. When working in data hold mode, you can display the values with the SELECT button.

Differential Absorption Ratio (DAR) and polarization index (PI)

There are cases in which no further intact isolation parts (which e.g. have lost their isolating effect under high voltage) but which still present a good absorption ratio (or a good polarization index). The absorption ratio (polarization index) can only be used to ascertain local isolation damage; they offer no indication as to dampness and contamination.

$$ \begin{array}{l l} \text {DAR (absorption ratio) =} & \frac {R 6 0 S e c}{R 1 5 S e c} \ \text {PI (polarization index) =} & \frac {R 1 0 M i n}{R 1 M i n} \end{array} $$

R10Min= resistance value measured 10 minutes after applying the test voltage; R1Min=R60Sec= resistance value measured 1 minute after applying the test voltage; R15Sec= resistance value measured 15 seconds after applying the test voltage

After completing the insulation test, press the SELECT button to display the DAR and PI values. Should the DAR and PI values be invalid, the display will show - - - .
