WARNING:
If the test leads are left in the sockets during replacement of the batteries or the
package of accumulators, there is a risk of electric shock with a dangerous
voltage.
In order to replace the package of accumulators it is necessary to do the following:
Remove all the test leads from the sockets and turn the meter off,
Remove the four screws of the accumulators/batteries compartment (in the lower part of the
casing),
Remove the compartment,
Insert the compartment in the meter,
Replace the four screws of the accumulators/batteries compartment.
NOTE!
Do not use the meter when the accumulator compartment is removed or open
or power it from other sources than those mentioned in the present manual.
6.3
Fuse replacement
Remove the battery compartment to get access to two replaceable fuses:
- FST 250Vac 1A, 5x20mm and
- 2A 250Vac, time-delay fuse, 5x20mm.
If the instrument or battery charger does not work, before sending it for servicing, check the fuses
and, if they are blown, replace them with identical ones. The fuses are placed in holders, near the
centre of the cavity. To remove the fuses, use a narrow tool (e.g. a screwdriver).
6.4
Charging of accumulators
Charging commences once the power supply has been connected to the meter regardless of the
fact whether the meter is on or off. During charging the screen looks as it is presented in the follow-
ing illustration. The accumulators are charged in accordance with the algorithm of „quick charge” –
this process permits to reduce the duration of charging to approximately four hours. The end of the
process of charging is signalled by:
Charging concluded
. In order to turn the device off, remove the
power supply plug of the charger.
