Test Leads; Measuring And Testing - VOLTCRAFT VC33 Bedienungsanleitung

6.5 Test leads

■
Only use test leads or accessories that match the multimeter specifications.
■
Do not use damaged test leads. Check the test leads for signs of damage be-
fore use.
■
Never take measurements if the protective insulation of a test lead 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 insulation is a different colour). If this occurs, discontinue use and replace
the test lead.
■
When using test probes without protective caps, measurements between the
multimeter and the earth potential 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.

6.6 Measuring and testing

■
Do not use a damaged multimeter. Check the multimeter for signs of damage
before use.
■
Consult an expert when in doubt about the operation, safety or connection of
the product.
■
Exercise particular caution when working with voltages higher than 33 V (AC)
and 70 V (DC)! Touching electrical conductors with these voltages can cause a
fatal electric shock.
■
Always ensure that the multimeter is set to the correct measurement mode be-
fore taking a measurement.
■
To prevent an electric shock, do not touch the measuring points when taking
measurements, either directly or indirectly. When taking measurements, do not
touch any area beyond the grip markings on the probe tips.
■
Always remove the test probes from the measured object before changing the
measurement range.
■
Do not use the multimeter when the battery compartment is open or when the
battery compartment cover is missing.
