1. Connect the Model 2350-1 to the pulser.
2. Set the pulse frequency to 600k cpm.
3. Select the Alarm Display (SVD3).
4. Set the integrated dose alarm to 100k cpm (P1E5).
NOTE: If an alarm is indicated press the ACK/SCRL button to silence the audio.
5. Select the Main Display (SVD0) and zero the integrated dose (SIZ). The Integrated dose counter
should start counting immediately and an alarm should be indicated when it reaches 100k cpm.
After the alarm press the ACK/SCRL button to silence the audio.
6. Select the Alarm Display(SVD3) and set the scaler alarm to 60,000 counts (K60000).
7. Return to the Main Display (SVD0), set the scaler count time to 6 seconds (F6), and take a scaler
count (C). When the scaler reaches 60,000 counts an alarm should again be indicated. Press
the ACK/SCRL button again to silence the audio.
8. Adjust the pulse frequency of the pulser to less than 600k cpm.
9. Select the Alarm Display (SVD3) and set the ratemeter alarm to 600k cpm (J6E5).
10. Select the Main Display (SVD0) and readjust the pulse frequency to a setting of 600k cpm. The
ratemeter alarm should be triggered. Press the ACK/SCRL button to silence the audio.
11. Verify that the ratemeter (RAT), scaler (SCL), and integrated dose (DOS) indicators are all
alternating with the alarm (ALM) indicators at 1 second intervals.
12. Select the alarm display (SVD3)
13. Set all of the alarms to their default high settings (ratemeter, J1E9; scaler, K1000000;
integrated dose, P1E9)
14. Select the Main Display (SVD0) and reset all of the alarm indicators (X).
15. Disconnect the instrument from the pulser and place it into the instrument can.
The electronics have now been calibrated and functionally checked. All remaining calibration
procedures involve setting the programmable parameters of the instrument and are covered in the
Model 2350-1 Data Logger Instruction Manual.
