Probes - VOLTCRAFT VC171 Bedienungsanleitung

• Never operate the product in direct proximity of strong magnetic or electromagnetic
fields or transmitter aerials or HF generators. This could affect measurement.
• For accurate measurements, replace the battery when the low battery symbol
appears on the display.
• Pay attention to the information besides the warning signs
terminals. The measured voltage or current must not exceed the values shown!
• Never operate the meter when the case is open. !DANGER TO LIFE!
f) Probes
• The probe cables have a wear indicator. When damaged, a second insulation
layer in a different colour becomes visible. The measuring accessories must no
longer be used and must be replaced.
• During measuring, do not grip beyond the grip range markings indicated on the
measuring probes.
• When using the measuring probes without cover caps, measurements between
the meter and the earth potential must not be performed above the measuring
category CAT II.
• When measuring in the measuring category CAT III. Measuring probes with cover
caps (max. 4 mm free contact length) must be used to avoid accidental short
circuits during measurement. They are enclosed.
• The measuring probes must be removed from the measured object each time the
measuring function is changed.
• The voltage between the connection points of the meter and the earth potential
must not exceed 600 V DC/AC in CAT III.
• Risk of fatal electric shock! Be careful
when dealing with voltages higher than
AC 30 Vr.m.s, 42.4 Vpeak or DC 60 V.
• Probe assemblies to be used for MAINS
measurements should meet EN 61010-
031 standard, rated CAT III 600V, 10A
or better.
