5.1 Maintenance
The measuring instrument is largely maintenance-free. The
maintenance required consists merely of changing the lamp
module and replacing the batteries.
5.1.1 Changing the lamp module
1 Switch off the measuring instrument and disconnect
it from the mains
2 Take out the lamp module (1): Press the two grips
gently together and carefully pull out the lamp mod-
ule until the plug-in connection (2) is visible
3 Pull the plug-in connection (2) apart and, thus, re-
move the lamp module. Do not pull on the wires while
doing this
4 Plug in the new lamp module to the plug-in connec-
tion of the instrument. Do not touch the lamp with the
fingers
