6.1 Inspection
To maintain the operator’s safety and to ensure the reliability of the instrument it is
advisable to inspect the instrument on a regular basis. Check that the instrument and its
accessories are not damaged. If any defect is found please consult your service center,
distributor or manufacturer.
6.2 Insertion and charging batteries for the first time
Battery cells are stored in the bottom section of the instrument casing under the battery
cover (see
Fig. 15
). When inserting batteries for the first time please note the following:
Disconnect any measurement accessories or mains supply cable connected to
the instrument before opening the battery cover to avoid electric shock.
Remove the battery cover.
Insert batteries correctly (see Fig. 15), otherwise the test instrument will not
operate!
Replace the battery cover and fixed the cover back in place.
Connect the instrument to the mains power supply for 14 hours to fully charge batteries.
(Typical charging current is 300 mA).
When you charge the batteries for the first time, it normally takes about 3 charge and
discharge cycles for the batteries to regain full capacity.
6.3 Replacement and charging batteries
The instrument is designed to be power by rechargeable battery supported by mains
supply. The LCD contains an indication of battery condition (upper left section of LCD).
When the low-battery indication appears (
Err
) the batteries have to be recharged,
connect the instrument to the mains power supply for 14 hours to recharge cells. Typical
charging current is 300 mA.
Note:
Operator does not need to disconnect the instrument from mains supply after the full
recharging period. The instrument can be connected permanently.
Fully charged rechargeable batteries can supply the instrument for approx. 4 hours.
(Continues testing at 5kV)
If the batteries have been stored for a long time, it normally takes about 3 charge and
discharge cycles for the batteries to regain full capacity.
Battery cells are stored in the bottom section of the instrument casing under the battery
cover (see
Fig. 15
). In case of defective batteries please note the following:
