CAUTION!
The PAT-1/2/2E/10 testers are powered from SONEL battery pack, which in-
cludes NiMH 7,2V batteries, and it may be replaced only by the authorized
service point.
The PAT-1/2/2E/10 testers feature built-it battery charger that only works with the original battery
pack provided by the manufacturer.
Charging commences once the power supply has been connected to the tester regardless of the fact
whether the tester is turned on or off. The only difference is the charging mode, as described below.
The charging process is indicated on the screen by displaying animated symbol of battery be-
ing charged.
Battery charging modes:
- the tester (user interface) is switched off: the battery pack is charged in ‘quick charging’ mode - the
charging process takes approx. 4 hours. Completed charging is indicated by full battery symbol,
FULL message and beep. In order to completely turn off the tester, unplug the power charger.
- the tester (user interface) is switched on: the battery pack is charged in ‘charging in the background’
mode.
In order to completely turn off the tester, unplug the power charger and turn the tester off.
CAUTION!
Do not power the meter from sources other than those listed in this manual.
Notes:
- Due to the interferences in the mains, the process of battery charging may finish prematurely. When
charging time is too short, turn off the tester and start charging again.
