Gain Test
Allow 24 seconds on this measurement.
Connect a 4.7 x 10
ohm resistor from the +15 volt supply to the
10
pre-amp input terminal.
Measure TP1 voltage. It should be between 3.9 V and 4.6 V, with
optimum measurement at 4.2 V.
The absolute voltage is not as important as the stability of the voltage.
Variance after stabilization must be less than 10 mV.
Remove the 4.7 x 10
ohm resistor.

Disassembly
Disassembly of the instrument is not allowed.
The only exception to this statement is for those with a Specific License
that contains special permission to separate the source housing from the
pipe.
Persons with a General License are never allowed to disassemble the
source housing from the pipe.
Additionally, the Type A shipping certificate is issued to the instrument as
a single component consisting of the detector, source housing, and pipe. If
the source housing is separated from the pipe, it is no longer covered by the
Type A shipping certificate.
