Battery and Fuse Replacement
NOTE: Make sure that no terminals are connected and that the switch is
in the OFF position before opening the front panel.
Replacing the battery causes data to be lost from the memory.
The battery should only be replaced by a qualified technician or
sent back to the factory for replacement and standard calibration.
See the Repair and Calibration section for return instructions.
Before replacing the internal batteries or fuses, the front panel
must first be removed. Use a Phillips Head screwdriver to remove
the four screws from the feet on the bottom of the case.
Pull out the chassis from the top.
The two fuses are located on the left side of the chassis.

resistance, protecting the current source from outside voltages on
energized specimens.
Fuse F2, is a 5.0x20 mm, fast acting, 2A/250V, protecting the
