fore taking a measurement.
Always remove the test probes from the measured object before changing the
measurement range.
Check the multimeter and test leads for signs of damage before each measure-
ment. Never take measurements if the protective insulation is damaged (torn,
missing, etc.). The test leads come with a wear indicator. The second layer of
insulation will become visible if the lead is damaged (the second layer of in-
sulation is a different colour). If this occurs, discontinue use and replace the
measurement accessory.
The voltage between the multimeter connection points and the earth must not
exceed 1000 V DC/AC in CAT III or 600 V DC/AC in CAT IV.
Exercise particular caution when working with voltages higher than 33 V (AC)
and 70 V (DC)! Touching electrical conductors with these voltages may cause
a fatal electric shock.
When using test probes without protective caps, meas-
urements between the multimeter and the earth poten-
tial must not exceed the CAT II measurement category.
When taking CAT III measurements, the protective
caps must be placed on the probe tips (max. length
of exposed contacts = 4 mm) to avoid accidental short
circuits. These are supplied with the device and pre-mounted on the test probes.
If it is no longer possible to operate the product safely, stop using it and prevent
unauthorised use. DO NOT attempt to repair the product yourself. Safe opera-
tion can no longer be guaranteed if the product:
– is visibly damaged,
– is no longer working properly,
– has been stored for extended periods in poor ambient conditions or
– has been subjected to any serious transport-related stress.
