Do not expose the device to shocks or strong vibrations.
The case should only be opened by qualified PCE Instruments personnel.
Never use the instrument when your hands are wet.
You must not make any technical changes to the device.
The appliance should only be cleaned with a damp cloth. Use only pH-neutral cleaner,
no abrasives or solvents.
The device must only be used with accessories from PCE Instruments or equivalent.
Before each use, inspect the case for visible damage. If any damage is visible, do not
use the device.
Do not use the instrument in explosive atmospheres.
The measurement range as stated in the specifications must not be exceeded under
any circumstances.
NEVER apply voltage or current to the meter that exceeds the specified maximum:

USE EXTREME CAUTION when working with high voltages.
DO NOT measure voltage if the voltage on the “COM” input jack exceeds 1000 V above
earth ground.
NEVER connect the meter leads across a voltage source while the function switch is in the current, resistance, or diode mode. Doing so can damage the meter.
ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests.
ALWAYS turn off the power and disconnect the test leads before opening the covers to replace the fuse or batteries.
NEVER operate the meter unless the back cover and the battery and fuse covers are in place and fastened securely.

3.15 Application Example
Power tools and small appliances This test would also apply to other similar equipment that has a line cord. For double insulated power tools, the megohmmeter lead shown connected to the housing would be connected to some metal part of the tool (e. g. chuck, blade). Note: The switch of the device must be in the “ON” position and the main power should be disconnected.
Motors AC-Disconnect the motor from the line by disconnecting the wires at the motor terminals or by opening the main switch. If the main switch is used and the motor also has a starter then the starter must be held, by some means, in the “ON” position. In the latter case, the measured resistance will include the resistance of the motor, wire and all other components between the motor and the main switch. If a weakness is indicated, the motor and other components should be checked individually. If the motor is disconnected at the motor terminals, connect one megohmmeter lead to the grounded motor housing and the other lead to one of the motor leads. DC-Disconnect the motor from the line. To test the brush rigging, field coils and armature, connect one megohmmeter lead to the grounded motor housing and the other lead to the brush on the commutator. If the resistance measurement indicates a weakness, raise the brushes off the commutator and separately test the armature, field coils and brush rigging by connecting one megohmmeter lead to each of them individually, leaving the other connected to the grounded motor housing. The above also applies to DC generators.

Cables Disconnect the cable from the line. Also disconnect opposite end to avoid errors due to leakage from other equipment. Check each conductor to ground and /or lead sheath by connecting one megohmmeter lead to a ground and /or lead sheather and the other megohmmeter lead to each of the conductors in turn. Check insulation resistance between conductors by connecting megohmmeter leads to conductors in pairs.
3.16 Autoranging/Manual Range Selection

4 Maintenance
To avoid electric shock, disconnect the test leads from any source of voltage
before removing the back cover or the battery or fuse covers.
To avoid electric shock, do not operate your meter until the battery and fuse
covers are in place and fastened securely.
This multimeter is designed to provide years of dependable service, if the following care instructions are observed:
• KEEP THE METER DRY. If it gets wet, wipe it off.
• USE AND STORE THE METER IN NORMAL TEMPERATURES. Temperature extremes can
shorten the life of the electronic parts and distort or melt plastic parts.
• HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the electronic parts or the case.
• KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth. DO NOT use chemicals, cleaning solvents or detergents.
• USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND TYPE. Remove old or weak batteries so they do not leak and damage the unit.
IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries should be removed to prevent damage to the unit.
4.1 Battery Installation
To avoid electric shock, disconnect the test leads from any source of voltage
before removing the battery cover.
Turn power off and disconnect the test leads from the meter.
Open the rear battery cover by removing two screws (B) using a Phillips head screwdriver.
• Insert the battery into battery holder, observing the correct polarity.
• Put the battery cover back in place. Secure with the screws.
To avoid electric shock, do not operate the meter until the battery cover is in
place and fastened securely. Note:
If your meter does not work properly, check the fuses and batteries to make sure that they are still good and that they are properly inserted.

• Disconnect the test leads from the meter.
• Remove the protective rubber holster.
• Remove the battery cover (two “B” screws) and the battery.
• Remove the six “A” screws securing the rear cover.
• Gently remove the old fuse and install the new fuse into the holder.
• Always use a fuse of the proper size and value (0.5A/1000V fast blow for the 500mA range,
10A/1000V fast blow for the 20A range
• Replace and secure the rear cover, battery and battery cover.
To avoid electric shock, do not operate your meter until the fuse cover is in
place and fastened securely.

6 Test method of DAR and PI
Firstly, short press MAX/MIN in the Insulation switch, then press LOCK button. Secondly, press INSULATION TEST button to start the test of DAR and PI. One minute later, the test results of DAR will show on the screen. PI test results will show on the screen after 10 minutes. The reference value of DAR and PI are as following:
PI Standard
PI Value
2 4 (typically 3)
1 1.5
1
1.0 or less
Tested material status
Considered as good insulation (older types)
Not acceptable (older types)
(very high insulation resistance) Modern type of (good) insulation system
Fail
Example:
If the reading of B-class insulation material is 100M in 1minute, 110MΩ in 10 minutes, polarization index is 1.1(110MΩ/100MΩ=1.1). As the insulating material contains too much
water or seriously polluted, the polarization index is below the minimum acceptable value, you need to repair or replace parts.
DAR Standard
DAR Value
1.6 or more
1.25-1.6
<1.25 OR less
Tested material status
Excellent
Pass
Fail

7 Warranty
You can read our warranty terms in our General Business Terms which you can find here:
https://www.pce-instruments.com/english/terms.
8 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 re-use 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.
