Velleman DVM400 Serie Notice D'emploi page 5

WARNING:
For safety reasons, please read the manual.
Remark: this warning is also found on the back of the meter (top part).
WARNING: To avoid electrical shock always disconnect the test leads
prior to opening the housing. To prevent damage or injury, only use
batteries and fuses with the same ratings as specified in this manual.
Remark: refer to the warning on the back of the meter.
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.
Protect this device from shocks and abuse. Avoid brute force
when operating.
Pollution degree 2-device. For indoor use only. Keep this device
away from rain, moisture, splashing and dripping liquids. Not for
industrial use. Refer to §5 Pollution degree.
Keep the device away from children and unauthorised users.
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 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.
This is an installation category CAT IV 600V / CAT III 1000V
measuring instrument. Never use this equipment in a higher category
than indicated. Refer to §4 Overvoltage /installation category.
Read this manual thoroughly. Familiarise yourself with the functions of the
device before actually using it.
All modifications of the device are forbidden for safety reasons. Damage
caused by user modifications to the device is not covered by the warranty.
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.
Make sure the meter is in the appropriate measuring range before
connecting it to a test circuit.
Do not measure circuits that may contain voltages > 1000V (DC or rms
AC)
Do not measure current in circuits with voltages > 1000V
Do not conduct resistance, diode- or continuity measurements on live
circuits.
Before each use, make sure the test probes are in good condition. Always
place your fingers behind the protective edges of the test probes while
measuring! Never touch free terminals when the meter is connected to a
circuit.
Switch off the meter and remove test probes prior to replacing the battery
or fuses.
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.
