1.1 Safety symbols
There are several icons on the meter which mean the following:

| This icon can be found next to another symbol or a connection and is a reference to the user manual.
---|---
| This icon indicates that high voltage could be present. Shock hazard!
| Double insulation
| Earth (ground)
| DC (direct current)

1.2 Safety categories

Category	Short description	Typical applications
CAT II	One-phase measurements, e. g. of sockets or cables	Household

appliances, electric power tools, measuring points 10 m away from a CAT III source, measuring points 20 m away from a CAT IV source
CAT III| Three-phase measurements or one-phase measurements, e. g. of light circuits in commercial buildings| Motors, switches, sub-distributors in a three phase circuit, light circuits in commercial buildings, supply cables for industrial plants, electrical appliances or connections near a CAT III source

The measuring category (CAT) arise from the combination of the meter, the test leads and the accessories. To know what CAT to work with, you must find out what component has the lowest CAT and use this CAT.
Important: When you have removed the insulation from the test leads, these will correspond to CAT II.

Turn on meter

To turn on the meter, select the desired function by turning the rotary switch. The meter will power on directly. To turn off the meter, select “OFF” with the rotary switch.

Connect the test leads

Connect the red test lead to the V input jack. Connect the black test lead to the COM input jack.

6.1 Set zero point
To reset the zero point, choose “400” with the rotary switch. Now hold the measuring tips against each other. Then press “ZERO”. The zero point has been reset.
Note: Zeroing is only valid for the “400” measurement and expires when you select a different measuring function.

Insulation measurement

To make an insulation measurement, select the desired voltage with the rotary switch. Here you can select a test voltage of 125 V, 250 V, 500 V or 1000 V. Now connect the test leads to your sample. Press the TEST key to generate the desired test voltage directly. To make a measurement, press and hold the TEST key. The measurement is finished when you release the key. Bear in mind that some residual voltage may be present in the meter. The reading will be shown in the upper part of the display. The test voltage is shown in the lower part of the display. The measurement range is selected by the meter automatically.
Note: If the sample carries a voltage of at least 30 V, the meter will display “>30 V” and ” “, a beep sound will be audible and the meter will not make a measurement. Therefore, it is important to remove any external voltages before each measurement.

7.1 Measuring AC motors
Interrupt the voltage supply of the motor by disconnecting the connection cable of the motor. In case there are switches on the motor, these must be turned on. To measure the insulation now, connect one test lead to the supply cable and the other one to the motor.

7.2 Measuring DC motors
Interrupt the voltage supply of the motor by disconnecting the connection cable of the motor. In case there are switches on the motor, these must be turned on. Now connect one test lead to the PE connection of the connection cable and the second one to, for example, the carbon brushes to measure the insulation.

7.3 Measuring insulated cables
To measure the insulation of a cable, make sure that the cable ends are open. Now make a measurement by measuring each cable core with every other cable core.

Continuity test/resistance measurement

To make a continuity test or resistance measurement, select “400” with the rotary switch. You can now connect the test leads to your sample and measure the resistance. The measurement range is set automatically. The continuity test takes place at the same time.
Note: If the sample carries a voltage of at least 30 V, the meter will display “>30 V” and ” “, a beep sound will be audible and the meter will not make a measurement. Therefore, it is important to remove any external voltages before each measurement.

Voltage measurement AC/DC

To measure alternating current, select “750V” with the rotary switch. Now you can connect the test leads to your sample. The present voltage will directly be shown in the upper part of the display. The current battery voltage will be shown in the lower part of the display. To measure direct current, turn the rotary switch to the “1000V” position. Then connect the test lead to the sample. The reading will be shown directly in the upper part of the display. The measurement range is determined automatically for both functions.

Automatic Power Off function

The meter turns off automatically after 10 minutes of inactivity. This function cannot be disabled. To turn on the meter again after auto power off, turn the rotary switch back to “OFF” and then turn it o the desired position.

Keys

The meter has four keys which have the following functions:

11.1 Hold reading
Press the HOLD key to freeze the reading. “HOLD” will be displayed. Press the HOLD key again to continue with the measurement. “HOLD” will now disappear.

11.2 MAX/MIN
Press and hold the MAX/MIN key to start the MAX/MIN function. “MAX” will appear in the display first. This function will display the maximum reading. Press the key again to view the lowest value. “MIN” will be displayed. Press and hold this key to return to normal measuring mode. Note: This function is only available with the measuring functions “400”, “1000VDC” and “750VAC”.

11.3 Freehand measurement (LOCK key)
Press the LOCK key. A lock icon will appear in the display. Now press the TEST key. An audible signal indicates that voltage is now present in the measuring tips. This voltage will be shown as a reading in the lower part of the display. The currently measured resistance value is shown in the upper part of the display. The high voltage is discharged as soon as the TEST key is pressed again. This procedure can be followed by looking at the lower part of the display. When the discharge is completed, the beep sound will be muted and the measuring tips can be removed safely.

Backlight

To enable the backlight, press and hold the ZERO key until the backlight is activated. To turn off the backlight, press and hold the ZERO key again. The backlight will turn off automatically after 15 seconds.

Replace the batteries

If the battery power is no longer sufficient, the battery icon will be displayed. To replace the batteries, first remove the test leads from the meter and turn it off. Now open the battery compartment at the rear side the cover of which is affixed with four screws. After opening the battery compartment, insert six 1.5 V AA batteries. Close the battery compartment.

Replace the fuse

To replace the fuse, first remove the test leads form the meter and turn it off. Open the battery compartment at the rear side the cover of which is affixed with four screws. Remove all batteries. You can now replace the fuse. Only use an FF 500 mA 1000 V fuse.

Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either reuse them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.
If you have any questions, please contact PCE Instruments.
