Inserting and Changing the Batteries
Operation of the measuring device requires a 9V battery (e.g. 1604A). You need to insert a
new, charged battery prior to initial operation or when the battery change symbol appears on
the display.
Proceed as follows to insert or change the batteries:
• Separate the connected measuring lines from the measuring circuit and the measuring de-
vice. Switch off the DMM.
• Open the housing as described in chapter “Opening the Measuring Device”.
•
Replace the flat batteries with new one of the same type. Place a new battery into the battery
compartment (18), observing the correct polarity. Observe the correct polarity indicated in the
battery compartment.
• Now close the housing again carefully.
Never operate the measurement device when it is open. !RISK OF FATAL INJURY!
Do not leave flat batteries in the device. Even batteries protected against leaking
can corrode and thus release chemicals which may be detrimental to your health or
destroy the battery compartment.
Do not leave batteries lying around carelessly. They could be swallowed by children or
pets. If swallowed, consult a doctor immediately.
Remove the batteries if the device is not used for longer periods of time to prevent
leaking.
Leaking or damaged batteries may cause alkali burns if they come in contact with the
skin. Therefore, use suitable protective gloves.
Make sure that the batteries are not short-circuited. Do not throw batteries into the fire.
Batteries must not be recharged or dismantled. Danger of explosion!
You can order suitable alkaline batteries stating the following order no.:
Item no. 65 25 09 (please order one).
