Replacing the main fuses

Warning
• The calibrator must be switched off before any attempt to service the instrument is
made. There are no user serviceable parts inside the calibrator.
• The fuse box must not be removed from the power control switch until the mains
cable has been disconnected.
• The two main fuses must have the specified current and voltage rating and be of the
specified type. The use of makeshift fuses and the short-circuiting of fuse holders
are prohibited and may cause a hazard.
A. Locate the main fuses in the fuse box in the power control switch and check the
voltage of the power control switch (on/off switch (230V/115V)). If the voltage of
the power control switch differs from the line voltage, you must adjust the voltage
of the power control switch.
B. Open the lid of the fuse box using a screwdriver and remove the fuse box.
C. Replace the fuses. The fuses must be identical and should correspond to the line
voltage.

If the fuses blow immediately after you have replaced them, the calibrator should
be returned to the manufacturer for service.
D. Slide the fuse box into place with the correct voltage turning upwards.
