5. During Use
Risk of electric shock during operation. Be very careful when
measuring live circuits.
•
If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
•
Never exceed the limit value for protection. This limit value is listed
separately in the specifications for each range of measurement.
•
Do not touch unused terminals when the meter is linked to a circuit
which is being tested.
•
Never use the meter with CAT III installations when measuring voltages
that might exceed the safety margin of 600 V above earth ground.
•
Set the range selector at its highest position if the intensity of the
charge to be measured is unknown beforehand.
•
Disconnect the test leads from the tested circuit before rotating the
range selector in order to change functions.
•
When carrying out measurements on a TV set or switching power
circuits, always remember that the meter may be damaged by any high
amplitude voltage pulses at test points.
•
Always be careful when working with voltages above 60 VDC or 30 VAC
rms. Keep your fingers behind the probe barriers at all times during
measurement.
•
Never perform resistance, diode or continuity measurements on live
circuits. Make sure all capacitors in the circuit are depleted.
