6.3 ADJUSTING THE HV
6.3.1 Remove the DSM-502 from its housing.
6.3.2 Determine if the HV that is required to operate the Internal probe is correct.
6.3.3 Adjust the MAIN SELECTOR SWITCH TO RATEMETER POSITION
6.3.4 Using a small screwdriver adjust SW4 to position 6. The number displayed will be the HV on
the Internal Probe. Adjust the #1HV potentiometer to read the required HV (±10 vdc) on the
display
6.3.5 Adjust SW4 to the 0 POSITION.
6.3.6 THIS COMPLETES THE ADJUSTMENT OF THE HV.
6.4 DISABLING THE ALARM & OVERANGE ALARM BEFORE CALIBRATION
6.4.1 To disable the OVER RANGE & REGULAR ALARM before calibrating adjust the MAIN
SELECTOR switch to RATEMETER OR COUNT depending on which alarms you want
disabled.
6.4.2 To disable the OVER RANGE ALARM adjust SW4 to position 3 and depress SW5 so that
CAL is visible on display
6.4.3 Adjust P1 & P2 until the display indicates 0.
6.4.4 Depress SW5. This completes disabling the OVERRANGE ALARM.
6.4.5 To disable the REGULAR ALARM
6.4.6 Leave the MAIN SELECTOR SWITCH at the same setting as was used to disable the OVER
RANGE ALARM
6.4.7 Adjust SW4 to position 2 and depress SW5 until the CAL is visible on the display
6.4.8 Adjust P1 & P2 until display indicates 0. Depress SW5 to save the reading.
6.5 ADJUSTING THE CALIBRATION CONSTANT FOR THE PROBE
GENERAL: The CALIBRATION CONSTANT adjustment is the CALIBRATION POINT for the
LOW END OF THE PROBES OPERATING RANGE. This adjustment is
completed utilizing P1, P2&P3. P2 acts as a COURSE adjustment and P1 acts as a
FINE adjustment. P3 is utilized to adjust the 0.1 part of the display these
potentiometers will become active for the calibration process when SW4 is in the
correct position and SW5 is depressed. The CAL on the display will be visible when
SW5 has been depressed and the meter is in the CALIBRATION MODE. SW5
MUST BE DEPRESSED AT THE END OF THE ADJUSTMENT OR THE DATA
WILL NOT BE SAVED
INTERNAL PROBE CC ADJUSTMENT

6.5.2 Determine the DOSE range of the probe that will be calibrated for the Internal Probe.
6.5.3 Adjust the MAIN SELECTOR SWITCH TO THE RATEMETER POSITION.
6.5.4 Adjust SW4 to the #4 position. Depress SW5 so that CAL is visible.
