is carried out at the end of fail time and, where appropriate, the
error message "Failure" is output. Then this measurement will
start new. See section: 1.7 for information on how to calculate
the values.
Detector Mode: (Only for alpha beta contamination probes)
Three modes can be used for a detector with simultaneous al-
pha/ beta measurement:
Alpha/Beta simultaneously
Only alpha device
Only beta device
If you select alpha only or beta only, the device behaves as if it
were measuring only alphas or only betas. The results of the
other type of radiation don’t appear. With simultaneous al-
pha/beta measurement one can choose three display variants:
Alpha and beta values displayed large, alpha values large and
beta values on the info bar, beta values large and alpha values
on the info bar.
Transmissions for alpha and beta channel
Display or entry of a factor that takes into account the attenua-
tion through the grid. The entry is made separately for and .
Parameter has no influence to cps values.
Upper measuring range
Here, the upper limit value is specified for the allowable meas-
uring ranges of the probes. When exceeding the upper limit,
OVF is displayed instead of the measurement result. In this
case, the integral is stopped.
6.11.10 Factory setting
All parameters can be reset to factory settings. This function
clears all user-defined settings.
6.12 Alarm Type
Here you can set whether the alarm is to be triggered upon ex-
ceeding of the threshold or if the alarm is to be indicated visual-
ly only through the upper red LED. Optical and acoustic alarm
can also be set at the same time.
