If two detectors are connected, alternate readings
can be taken by switching between DET A and
DET B. Both detectors should be calibrated
concurrently.
The highest degree of calibration can be attained
by calibrating at a dose or dose rate near ½ scale
(1000 cGy or 1000 cGy/min). This is due to display
resolution.
After the battery check, instrument zeroing, and calibration have been performed, measurements can be
taken.
2.4 Making a Measurement
Rate: cGy/min
1. Zero the instrument if not previously zeroed. Refer to "Zeroing the Instrument", at the beginning of
Section 2.2.
2. Connect the appropriate probe/probes to the DET A, DET B inputs.
3. Select the RATE mode on the front panel.
4. Initiate a radiation exposure.
5. During the exposure, view the reading on the display.
Dose Mode: cGy
1. Zero the instrument if not previously zeroed. Refer to "Zeroing the Instrument", at the beginning of
Section 2.2.
2. Connect the appropriate probe/probes to the DET A, DET B inputs.
3. Select the DOSE mode on the front panel.
4. Initiate a radiation exposure.
5. Upon completion of the exposure, view the results on the front panel display.
6. Alternate between DET A and DET B to view both channels.
