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.

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

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.

witch off the meter and remove test probes prior to replacing the battery
