Sensor rating
The rating of the sensor state is calculated and saved after each successful
calibration.
Watch sensor rating:
Press shortly the
key, the display shows for a short
time i.e.
= 100%.
The rating is displayed in 10 percent steps: 100% = optimal sensor status. Lower
values are indicating that the sensor life time will soon be reached. (50% doesn’t
mean 50% of the life time, but 50% of the reference signal!). But also a erroneous
pressure entry may cause low sensor ratings.
10 Replace sensor element
Unplug the sensor, unscrew the white protection housing and take the sensor
element. Take the rubber disk off and put it on the new sensor. Put the new sensor
element into the housing, screw it down and plug it.
Then start the calibration.
11 Errors and system messages
no
display
The battery is used up and has to be exchanged, or the device is
defective
The battery is used up, for a short period further measurements are
possible
The battery is used up and has to be replaced, measurements are no
more possible
Calibration error: sensor voltage is too low (sensor used up or wrong
chosen air pressure)
Calibration error: sensor voltage is too high (wrong chosen air
pressure or sensor defective (membrane crack, etc.)
Calibration error: signal not stable
Measuring error: range has been exceeded
Measuring error: measuring value has fallen below permitted range
System error: the device is defective or considerably out of the
allowed ambient temperature range
12 Display when switching-on the device
Start and display test
If switch-
off delay “P.oF” (power off) is active, this is signalled at the
turn-on procedure.
