11.1 Opening your Calibrator
There are a few cases in which you may have to open your calibrator.
1. To change the battery pack.
2. To change the fuse.
In order to open it, place it face down on a flat, hard surface and
unscrew the four screws as shown. Then gently pull the two halves
apart.
Caution: be very careful not to tear the keypad ribbon or damage the
electronics.
11.2 Changing the Batteries
If the battery pack fails you must order a new pack from your dealer. Use only the factory
supplied battery pack as it contains a temperature sensor. Open the calibrator as shown
above and then disconnect the old pack and replace it with the new one. Be careful not to
damage the electronics while the unit is open, an anti-static mat and wrist band should be
used. Do not force the connector.
11.3 Resetting the Unit
The unit may fail if it passes through a strong electro-magnetic field or is subjected to high
voltages or current. In this event there is a reset switch within the unit that should restart it.
Press the button through the small hole in the housing (near the power connector) using a
paper clip.
11.4 Changing the Fuses
The fuses may blow if over ranged. Open the unit to change the fuse.
There is one type a 250 mA input protection fuse.
The 250 milliamp input protection fuse, marked F4, can be found on the reverse side of the
PCB, positioned in the top left hand side.
Take the blown fuse out and replace it with the same rated fuse. Spare fuses can be ordered
from your dealer. See 13.0 Accessories for the part number.
