6.1. Preliminary Note
1.
To check the 9 V battery, please switch on the DMM. If the
battery is weak, a "LO BAT" or "BAT" sign will appear on the left of
Display. If this does not appear on the display proceed as below.
See "Maintenance" if the battery has to be replaced.
2.
The warning sign next to the test leads jack is for warning that the
input voltage or current should not exceed the indicated values.
This is to prevent damage to the internal circuitry.
3.
The function switch should be set to the range which you want to
test before operation.
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.
