Mirion Technologies RDS-32 - 5 Maintenance and Decontamination; Firmware Update

MAINTENANCE AND DECONTAMINATION
40
DG1.DF High voltage is not within specified range
DG2.DF Internal power supply is out of specified range
DG3.DF Firmware CRC error; the bit sum check of embedded software failed
LFE.DF Cumulative dose overflow (>10 Sv). The GM-detector can be at the end of life.
Should an error occur, write down the Error message and return the meter to the manufacturer
for service (for contact info: see the last page of this manual). The internal diagnostics memory
will also store critical errors, but in case the problem is the memory itself, it cannot be
completed.
5 MAINTENANCE AND DECONTAMINATION
No specific maintenance is required except for a periodic check of the calibration. The local
authorities typically determine the required checking interval. Once a year under demanding
conditions, or every second year under typical laboratory conditions is a recommended
interval in maintaining the proper operational reliability of the instrument.
5.1 FIRMWARE UPDATE
The CSW-32 Configuration Software is needed to perform a firmware update. Follow the
procedures outlined in the software manual to upload a new firmware to the RDS-32.
The latest RDS-32 firmware can be downloaded from mirion.com
Note! If the RDS-32 becomes unresponsive during a firmware update, don’t remove
the batteries, simply try to run the firmware update again.
A simple functional check of the meter can include switching it on and letting it run
though the self-check routine at start up. Leave the meter on additionally for several
minutes to check that the detector receives pulses as expected even at background
level, or use a small radiation source to check that the meter responds.
