4 Short product description

This insulation tester has all functions needed to check and verify electrical insulation.

The battery voltage is checked whenever the meter is powered on.

The meter complies with all usual standards.

The [ON/TEST] key is used to turn on the meter and to start and stop a measurement.

It is also used to disable the EnerSave function. To do so, press and hold the key for at

least 3 seconds when starting a measurement until you hear a short sound.

Measurements will no longer be interrupted after 10 seconds. You can now make

measurements of up to 10 minutes. If you wish to measure in the modes PI and DAR,

the EnerSave function must be disabled.

A measurement can be stopped at any time by pressing the [ON/TEST] key.

The [LOW] key is a multifunctional key. You can make a continuity test by pressing

this key but also initiate automatic zero setting of the test leads and the fuse. The

meter’s standard mode after startup is insulation test mode.

Before making a measurement (Make sure that the included test leads are connected

properly and that the fuse is in sound condition!), the meter will go through a voltage

test to make sure no voltage is present in the meter or circuit. If a voltage is present

which could cause a problem for the meter, the meter will switch directly to voltage

measurement and shows the reading in the display. If there is a voltage on the line,

the measurement will be terminated automatically and the keypad is locked to avoid

unintended operation. This makes this insulation tester one of the safest currently

available on the market.

You can start the measurement when no voltage is present anymore.

If you wish to measure insulation resistances, you can choose a test voltage of 250,

500 or 1000 V. If you wish to make a continuity test, use the [LOW] function to

measure low resistances of up to 0.01 . The acoustic signal will be on automatically.

You can zero the fuses and the test leads by using the „Auto Zero“ function.

The Auto Hold function enables you to concentrate on the test leads during the

measurement as you can conveniently view the reading on the display after the

measurement. Thisfunction is always enabled so that you can first measure the voltage

and then read out the last valid measured value on the display.

When dangerous voltages are present on the line to be measured, an acoustic signal

will sound.

5 Functions

5.1 [ON/TEST] key (on/off function)

When the [ON/TEST] key is pressed, the meter will power on, carry out an automatic battery test

under load and display the result.

The applied voltage will then automatically be measured and displayed. All functions of the meter

will be automatically disabled until no applied voltage is measured.

5.2 Battery test

The battery test is carried out automatically when the meter is turned on. For this test, a load will

be applied to the inserted batteries for a short time and the result will be shown in the display.

The battery level will be displayed at any time. The battery icon will flash if the battery level is too

low.

5.3 Voltmeter

There is no key for this measuring function as this is the meter’s standard mode. Before each test

and before the test leads are connected, the meter will measure the applied voltage (AC/DC).

5.4 Auto Hold

The Auto Hold function is always enabled (visible on the display).

This function holds the last valid measured value so that it is displayed even after disconnecting

the test leads. This allows you to concentrate on thetest leads during the measurement and view

the value on the display when the measurement is finished.

5.5 250 V, 500 V, 1 kV insulation resistance measurement

If you want to make an insulation resistance measurement, the test leads must be connected to

the circuit to be measured. If a voltage is present in the circuit, this voltage will be shown in the

display and the resistance measurement will be cancelled. An insulation resistance measurement

is only possible if no voltage is present.

If no voltage is present, press the key for the insulation resistance measurement and then start

the measurement by pressing the [ON/TEST] key. The measurement can be interrupted at any

time or is interrupted automatically, depending on the selected measuring mode (see EnerSave).

5.6 [ON/TEST] key (measuring function)

The [ON/TEST] key can be used to start and stop a measurement (see EnerSave).

5.7 EnerSave function

If you press the [ON/TEST] key to start a measurement, it will be terminated automatically after

10 seconds. If you wish to measure for a longer time, press and hold the [ON/TEST] key until you

hear a short sound, which means that the EnerSave function is disabled.

The EnerSave function must be disabled everytime you wish to make a longer measurement.

5.8 [LOW Ω] key for continuity tests

Press the [LOW Ω] key to make a continuity test. A short circuit current of 200 mA will be used.

The meter can display very small resistances of up to 0.01 ohms.

5.9 [LOW Ω] key for Auto Zero

Press the [LOW Ω] key to zero the resistance, the test leads and the fuse. This function is useful

if you use longer test leads.

Do not forget to short-circuit the test leads when making a zero setting.

5.10 [1000V] key for power off (Auto Power Off)

Press and hold the [1000V] key for 5 seconds to switch off the meter.

After 5 minutes without pressing any key, the meter will turn off automatically.

5.11 Automatic discharge after an insulation measurement

After each insulation measurement, the meter will be discharged automatically. The status of the

discharge will be displayed in the meantime. The discharge is finished when no voltage is present

any longer. Before that, the test leads must not be removed.

6 Safety checks before the measurement

Check the cables for damage and cracks and replace them, if required. Also inspect the fuse

before each measurement by holding the test leads against each other in [LOW Ω] mode. At the

same time, the measurement resistance will be set to zero. Always connect the test leads to the

circuit to be measured safely and correctly. Never interrupt the connection during a measurement

and do not touch the test tips or the sample asthe safety mechanisms are not fully effective during

the measurement. Always follow the instructions on the display. Do not start a measurement

before the test leads have been properly connected to the sample.

7 Changing the fuse

In order to change the fuse, follow these steps:

First remove all test leads. Now open the battery compartment and remove all batteries. Now

open the case by loosening both screws in the battery compartment. Now you can change the

fuse. Close the meter and re-insert the batteries. The meter can be used again when the battery

compartment has been closed.

8 Further information

PI =

Polarisation Index

The ratio between the insulation resistance value measured after the

application of the test voltage continuously for 10 minutes to the

insulation resistance value measured after 1 minute of application

DAR = Dielectric

Absoprtion Ratio

The ratio of the insulation resistance value typically measured at 30 sec

and 1 min

AUTO-ZERO

Zero the test leads and the fuse so that only the resistance of the

measurement range is shown when making a measurement.

The audible signal is always enabled. If the resistance is low, you will

hear a sound.

9 Warranty
