Battery Check
The instrument will automatically indicate a
battery low condition by the display of - .
To monitor the battery power level, select the
Battery Check position. The instrument will then
measure the battery voltage under a simulated
load. This value will be displayed. The analogue
arc represents the remaining battery life. A full
arc is equivalent to about 9 V and when the arc
is at its minimum the battery voltage will be
about 6 V.
Battery Replacement
When the low battery symbol
appears,
the cells are nearly exhausted and should be
replaced as soon as possible. Use Alkaline
cells IEC LR6 (AA) only. To install or replace
the cells, disconnect the test leads, switch the
instrument to OFF and loosen the captive
screws on the base of the instrument, holding
the battery compartment cover in place.
Remove the cover and lift out the cells. Ensure
that the replacement cells are fitted with the
correct polarity in accordance with the label in
the battery compartment. Replace and re-
secure the battery compartment cover.
Remove the cells if the instrument is not going
to be used for an extended period of time.
Fuse Checking and Replacement
To check the instrument fuse, switch to an
insulation range and press the TEST button.
The symbol
will appear if the fuse is
ruptured.
N.B. the voltmeter will continue to operate for
voltages greater than 100 V at 50 Hz.
To replace the fuse, disconnect the test leads,
switch the instrument OFF and loosen the
captive screws holding the battery
compartment cover in place. Use only a
500 mA (F) 440 V, 32 mm x 6 mm ceramic use
of high breaking capacity HBC 10 kA min.
Glass fuses
MUST NOT
be fitted. Remove the
cover and replace the fuse. Replace and re-
secure the battery compartment cover.
