SEPARATING THE CONTROL UNIT
The control unit of the Model 3450 can be separated easily from the
gauge. This enables the user to perform gauge setup, review data or
status information, and upload or print projects while the nuclear
sources are safely stored elsewhere.
The control unit is located on the top of the gauge and includes the
keypad and the display. Before removing the control unit, turn the
gauge off and disconnect the charger from the rear of the gauge.
NOTE
When working with multiple gauges, note which control
unit goes to which gauge. Because gauge calibration
constants are stored in the control unit, each control
unit must be returned to the gauge from which it was
removed.
Remove the control unit by loosening the four screws located in the
corners of the keypad. Lift the control unit and place it to the right
side of the gauge. Disconnect the ribbon cable where it enters the
left side of the control unit by pushing out on the two small latches
at the baseboard connector. On recent gauge revisions, the cable is
shielded and is secured to the control unit by a flat metal bracket.
Using a small Phillips screwdriver, remove the two screws that hold
the bracket.
CAUTION
– EUROPEAN COUNTRIES –
Do not separate the control unit from the base.
Doing so will result in non-compliance with EMC
directive. Call your Troxler representative for
additional information.
CAUTION
Turn the gauge off before disconnecting the control unit.
Unexpected operation or board failure may result if the
control unit is disconnected while turned on.
