Maintenance (cont'd)
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 under the battery cover
(see Fig. 15). In case of defective batteries please note the following:
• Turn the power off and disconnect any measurement accessories and the mains supply cable
before opening the battery cover to avoid electric shock.
• Remove the battery cover.
• All six cells have to be replaced.
• Insert the batteries correctly (see Fig. 15), otherwise the test instrument will not operate and
the batteries may be discharged.
• Replace the battery cover.
• The Instrument will only work when rechargeable batteries are inside the instrument.
Nominal power supply voltage is 7.2 V DC. Use six NiMH cells of C size (dimensions:
diameter = 26 mm, height = 46 mm). See the next figure Fig.15 for correct polarity of batteries.
1..........Correctly inserted batteries.
2..........Battery cover.
3..........Screw (unscrew to replace the batteries).
Ensure batteries are used and disposed of in accordance with Manufacturers guidelines and in
accordance with Local and National Governmental guidelines.
Disconnect all test leads and switch off instrument before
removing the battery cover!
