Remedy
perform empty/free calibration
("Abgleich" (*1) function group)
• Check: Has at least one calibration point been entered and activa-
ted?
If not: Enter and activate calibration point(s). ("calibration" (*1)
function group)
• Check: Is the "reference pulse rate" (*1F) larger than 2
If yes: re-perform density calibration ("calibration" (*1)) func-
tion group
enter present date
("basic setup" (*0) function group
"todays date" (*01) function)
check calibration date and enter it again
("system parameters" (*C) function group
"calibration date" (*C7) function)
enter operating mode
("basic setup" (*0) function group
"operating mode" (*04) function)
enter measurement mode
("basic setup" (*0) function group
"measurement mode" (*05) function)
enter at least two value paris "temperature density"
"temperature compensation" (*3) function group)
install water cooling jacket or thermal screening
install water cooling jacket or thermal screening
check correct functioning and connection of the PT-100 sensor
check calibration and linearisation
• 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)
wait for end of the gammagraphy measurement
