Remove the batteries and disconnect
the unit from other equipment. Take the
four T/C wire screws out and release all
visible phillips screws at the back and
inside the battery
compartment. Lift gently the
housing upper half off and put it a way.
Disconnect the powercable from the
board and the cable to the rotatable
unit. The electronic board assembly and
the rotatable unit can now be taken out
of the lower half of the housing.
To open the rotatable unit release the
two screws at the same half on each
side.
To close the calibrator housing in
reverse order the following must be
considered;
1. Place the rotatable unit back in the click
mechanism slots as found before.
2. Make sure that the cable between base
unit and rotatable unit is correctly routed
as indicated.
3. Put the three printed circuit board
spacers in place. Left hand and right
hand spacers have brass wire guide
tubes; make sure they fit into the mV
terminals correctly.
4. Check the "battery type" selector switch
position before turning the unit on.
