Inserting/Changing the Battery
GLM 100-25 C
Using alkali-manganese or nickel metal hydride rechargeable batteries (especially at low operating temperatures) is recommended for operation of the measuring tool.
With 1.2 V rechargeable batteries, more measurements may be possible than with 1.5 V batteries, depending on the capacity.
- Press the release button (7) and swing out the stop pin (8) by 180°.
- To open the battery compartment cover (17), flip the screw cap (25) up and turn it a quarter rotation anticlockwise.
- Lift the battery compartment cover (17) on the screw cap (25).
- Insert the batteries or rechargeable batteries.
- Always replace all the batteries/rechargeable batteries at the same time. Only use batteries/rechargeable batteries from the same manufacturer and which have the same capacity.
- When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment.
When the empty battery symbol first appears on the display, only a limited number of measurements are still possible.
When the battery symbol is empty and flashes red, no further measurements are possible. Replace the batteries or rechargeable batteries.
- Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The batteries can corrode and self-discharge during prolonged storage.
