Analog Output
The analog output is a five-decade logarithmic voltage-out. The maximum
voltage-out while under primary power is 6 volts. The maximum voltage out while
under battery backup power is 4.5 volts. The five decades are:
• 0.1<units> to 1.0 <units>*
• 1 <units> to 10 <units>*
• 10 <units> to 100 <units>*
• 100 <units> to 1000 <units>*
• 1000 <units> to 10000 <units>*
When the CAL MODE dip switch is switched to the right, the analog output goes
to full scale. The analog output goes to full scale during a DET FAIL condition.
Discriminator
The DISC potentiometer located under the calibration cover is used to set the
threshold for pulses coming from the detector. The desired pulse threshold
depends on the type of detector used. It is adjustable from 2.0 mV dc to
100 mV dc.
Battery Charge
The potentiometer labeled BAT, located under the calibration cover, is used to
set the backup battery trickle-charge voltage. This is typically set to 6.9 V dc with
the battery disconnected.
