• 7-CHECK ERROR
The status of the calibration parameters could not be fully veri-
fied. In this case, repeat the calibration. If the error occurs
again, replace the detector, at least the detector electronics.
The following additional settings are made at Cal Preset :
– Compensation Mode = OFF
– Calibration Method = Multipoint
– Lower calibration point set to 0%
– Upper calibration point set to 100%
– Cal Curve Type = Normal

At the end, fill out the commissioning log, see chapter 9 , page
3-441 .
Tip
Always carry out a test calculation after every calibration. This will
ensure that your calibration data are plausible and the detector is
set correctly (see
chapter 2.39 , page 3-366 , Cps Average Mode
and Cps Average Test ).
This completes the calibration.
Advanced functions
In addition to calibration with Quick Start , you can also calibrate
using the Cal Parameter menu. Further options are offer there,
such as:
– Single-point or multi-point calibration
– Empty, full adjustment with a known characteristic curve
– Upload, download of calibration parameters
– Calibration of products with natural radioactivity
– Calibration with gas density compensation
You can enable additional signals and messages in the menu Signal
Condition .
Via I/O Setup you can use existing or optional I/Os to output or
process signals.
In order to avoid the risk that the device supplies faulty signals, it
is imperative that you familiarize yourself with these additional fea-
tures before you use them.
