6.8 Test leads and probes
■
The voltage between the connection points of the meter and the earth potential
must not exceed 600 V AC/DC in CAT III.
■
Probe assemblies to be used for MAINS measurements should meet EN
61010-031 standard, rated CAT III 600 V, 40 A or better.
■
Risk of electric shock! Use caution when working with voltages above 30 V/AC
rms (42.4 V peak), 60 V/DC.
■
Test leads must be disconnected before changing the range / function.
■
The cables have a wear indicator. If damaged, a second insulation layer in a
different colour becomes visible. Do not use if this occurs, replace immediately!
■
When taking measurements do not grip beyond the finger barrier or grip range
markings on the probes.
■
When using the probes without cover caps, measurements between the meter
and the earth potential must not be performed above the measuring category
CAT II.
■
Prevent short circuits by ensuring test points/connections do not touch when
taking measurements.
■
Always check the probes and leads for any sign of damage before each use.
Do not use if damaged, replace immediately!

■
When taking CAT III measurements, probes
with cover caps (max. 4 mm free contact
length) must be used to avoid accidental
short circuits.
