A631 background not calibrated perform background calibration
("calibration" (*1) function group)
A632 full/covered not calibrated perform full/covered calibration
("calibration" (*1) function group)
A633 empty/free not calibrated perform empty/free calibration
("calibration" (*1) function group)
A634 density not calibrated • Check: Has at least one calibration point been entered and
activated?
If not: Enter and activate calibration point(s). ("calibration" (*1)
function group)
• Check: Is the "reference pulse rate" (*1F) larger than 2
32
?
If yes: re-perform density calibration ("calibration" (*1))
function group
A635 present date not defined enter present date
("basic setup" (*0) function group
"today's date" (*01) function)
A636 calibration date not plausible check calibration date and enter it again
("system parameters" (*C) function group
"calibration date" (*C7) function)
A637 operating mode not defined Enter operating mode
("basic setup" (*0) function group
"operating mode" (*04) function)
A638 measurement mode not defined enter measurement mode
("basic setup" (*0) function group
"measurement mode" (*05) function)
A639 temperature compensation not complete enter at least two "temperature - density" value pairs
("temperature compensation" (*3) function group)
W662 high sensor temperature (warning) install water cooling jacket or thermal shielding
A663 sensor temperature too high (alarm) install water cooling jacket or thermal shielding
A664 temperature measurement error check correct functioning and connection of the PT-100 sensor
W681 current out of range
(3.8 to 20.5 mA)
check calibration and linearization
A692 gammagraphy detected (alarm) • Check, if interference radiation is present or the "hold time"
(*54) is too short.
• If no interference radiation is present: decrease gammagraphy
sensitivity
("gammagraphy" (*5) function group
"sensitivity" (*52)function)
W693 gammagraphy detected (warning) wait for end of the gammagraphy measurement
W695 measurement counter overflow the local dose rate is too high (where applicable, reduce with blind
flange).
