TV 431 26 ENGLISH Safety The insulation tester was developed and manufactured in accordance with the requirements of the safety standard for electronic test instruments. The specifications for category III 1,000 V and pollution degree 2 were maintained entirely. 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. ⚫ Remove the test leads from the test instrument before opening the housing or the battery compartment of the test instrument. ⚫ Never commission the device unless the protective cover is in position or if the battery compartment is open. ⚫ Comply with the local and national safety specifications when working in hazardous environments. ⚫ Wear the correct protective equipment as specified in local and national regulations when working in hazardous environments. ⚫ Use only the specified replacement fuses; failure to do so will mean that the protection of the device is not guaranteed.Instrument description Testboy

The test voltage is displayed whilst an insulation test is being carried out. Press the △ button to display the time. Press the SELECT button to view the pre-set time frame. The LC display shows TIMER. The main display shows PRES; the auxiliary display shows the pre-set time frame. Press ENTER. The display shows ‘Set’. You can set the time-frame with the △/▽ buttons. Press ENTER again to accept this setting.Functional description Testboy

TV 431 34 ENGLISH 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.

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 - - - -.

TV 431 35 ENGLISH Basis measurements DC voltage measurement Move the rotary switch to V. Connect the input connections and test leads as shown here and connect the test leads to the voltage source / consumer.

AC measurement Move the rotary switch to V. Connect the input connections and test leads as shown here and connect the test leads to the voltage source / consumer.

Resistance and continuity measurement To avoid any damage to the test instrument or the system to be tested, disconnect the circuit power supply and discharge all the high-voltage capacitors before performing a continuity test. Move the rotary switch to Ω. Connect the test leads as shown. A signal will sound during the continuity test with a measured resistance of < 3 Ω.Basis measurements Testboy

Warning: To avoid damaging the test voltage, do not adjust the rotary switch when outputting the test voltage.

⚫ Insulation tests may only be performed on circuits free of voltage. Check the test leads before performing the insulation test. ⚫ Move the rotary switch to INSULATION. If the display shows , replace the batteries. ⚫ Connect the test leads to the connections High and Low. If the display shows ‘Live’ this means that a measurement cannot be performed, as the circuit is live. Switch the circuit voltage-free. ⚫ Select the output voltage with the TEST.V button. ⚫ The symbol will flash during the insulation test. The main display will show the resistance value and the auxiliary display will show the output voltage. Release the Test button. The discharge procedure is performed via the test instrument; the display will show DISC ⚫ The auxiliary display indicates when the discharge procedure has been completed (0 VDC). ⚫ Disconnect the test leads from the circuit.

Replacing the battery To avoid incorrect measuring results, which could lead to an electric shock or injury, replace the battery immediately when the display shows . Turn the rotary switch to OFF and disconnect the test leads from the connections. Unscrew and remove the cover of the battery compartment. Replace the batteries whilst complying with the polarity. Replace the cover of the battery compartment and screw down.Specifications Testboy
