6. How to make measurements

CAUTION!
Note on using the supplied safety test leads according the IEC / EN 61010-031:2008:
Measurements in the field of overvoltage category CAT I or CAT II can be performed with test leads
without sleeves with a maximum of up to 18mm long, touchable metallic probe, whereas for
measurements in the field of overvoltage category CAT III or CAT IV test leads with put on sleeves,
printed with CAT III and CAT IV must be used, and therefore the touchable and conductive part of the
probes have only max. 4mm of length.
Before making any measurements read safety precautions. Always examine the instrument and
accessories used with the instrument for damage, contamination (excessive dirt, grease, etc) and
defects.
Examine the test leads for cracked or frayed insulation and make sure the lead plugs fit snugly into the
instrument terminals. If any abnormal conditions exist, do not attempt to make any measurements.
Never exceed the maximum allowable input voltage of 1000 V AC / DC. Exceeding the risk of damage
to the device.
A maximum voltage difference of 1000 V AC / DC between the COM input and ground must not be
exceeded.
