Martel Electronics BetaGauge 3II - Manual (Page 29)

Input Modules 2-2
Installing and Removing Modules
You may insert or remove a module while the calibrator
is on or off. If the calibrator is on, the module will self-
initialize within 3 seconds and a reading will display on
the LCD.
When facing the calibrator, the left module bay
corresponds to Channel 1, and the right module bay
corresponds to Channel 2.
CAUTION: Use care when handling modules. It is
recommended that you store unused
modules in the carrying case supplied
with the calibrator. Careless handling of a
module could result in damage to the
module's miniature data connector.
Installation Procedure
Use the following procedure to install a module into the
BetaGauge II:
1. Insert the connector end of the module into the
appropriate module bay. Make sure the serial
number label faces up.
2. Insert the module into the module bay until it is
seated (approximately ¾ inches of the module will
be visible).
CAUTION: The keys and offsets on the module
connector are designed so that the module can be
inserted in one direction only. Excessive force
could damage the module or the calibrator.
NOTE: For information on how to select a channel for
performing specific functions, refer to
Section 3.
