Diagnostics
Display of calibration data, display of sensor data, performing a device
self-test, viewing the logbook entries, display of hardware/software ver-
sions of the individual components. The logbook can store 100 events
(00...99). They can be displayed directly on the device. The logbook can
be extended to 200 entries using a TAN (Option).
HOLD
Manual activation of HOLD mode, e.g. for servicing. The signal outputs
adopt a defined state.
Calibration
Every sensor has typical characteristic values. Calibration is required to
supply a correct measured value. The device checks which value the
sensor delivers when measuring in a known solution. When there is a
deviation, the device can be “adjusted“. In that case, the device displays
the “actual“ value and internally corrects the measurement error of the
sensor. During calibration the device is in HOLD mode.
During calibration the device remains in the HOLD mode until it is
stopped by the operator.
Configuration
The analyzer must be configured for the respective measurement
task. In the “Configuration“ mode you select the connected sensor, the
measuring range to be transmitted, and the conditions for warning and
alarm messages. During configuration the device is in HOLD mode.
Configuration mode is automatically exited 20 minutes after the last
keystroke. The device returns to measuring mode.
