3. Safety Instructions
Read this manual thoroughly. Familiarise yourself with the functions of the device
before actually using it.
Only use the device for its intended purpose. Using the device in an unauthorized
way will void the warranty. Damage caused by disregard of certain guidelines in this
manual is not covered by the warranty and the dealer will not accept responsibility
for any ensuing defects or problems.
Follow the instructions below to guarantee a safe use of the meter and all its
functionalities.
During use of the meter, respect all directives concerning protection against
electroshocks and misuse. Never exceed the indicated limits.
WARNING: To avoid electrical shock always disconnect the test leads prior to
opening the housing.
Remark: refer to the warning on the back of the meter
WARNING: To prevent fire, use exact fuses.
Remark: refer to the warning on the back of the meter
Keep the device away from children and unauthorised users.
Protect this device from shocks and abuse. Avoid brute force when operating.
Avoid cold, heat and large temperature fluctuations. When the unit is moved from a
cold to a warm location, leave it switched off until it has reached room temperature.
This to avoid condensation and measuring errors.
This is an installation category CAT III 600V / CAT II 1000V measuring
instrument. Never use this equipment in a higher category than indicated. Refer t
§4 Overvoltage /installation category.
Pollution degree 2-device. For indoor use only. Keep this device away from rain,
moisture, splashing and dripping liquids. Not for industrial use.
Pollution degree.
Before each use, make sure the test probes are in good condition.
fingers behind the protective edges of the test probes while measuring!
touch free terminals when the meter is connected to a circuit.
Make sure the meter is in the appropriate measuring range before connecting it to a
test circuit.
Risk of electric shock during operation. Be very careful when measuring live
circuits. Use extreme caution when measuring voltages higher than 60Vdc or 30Vac
rms.
Do not measure circuits that may contain voltages > 1000V
Do not measure current in circuits with voltages > 250V
Do not conduct resistance, diode- or continuity measurements on live circuits.
When measuring currents above 5A, max. 15s continuous measurement
a 10 minutes break between 2 measurements.
When carrying out measurements on a TV set or switching power circuits, always be
aware that high amplitude voltage pulses at the test points might damage the
meter.
Do not replace internal parts yourself. Replace damaged or lost accessories by
identical ones with the same specifications. Order spare accessories e.g. test probes
at your dealer.
