500 Sensor calibration
M
On
Off
All
No
Calibration aborted, main measured
value varies.
Reasons: sensor too old, sensor occasion-
ally dry, calibration value not constant.
1. Check sensor.
2. Check calibration solution.
501 Sensor calibration
M
On
Off
All
No
Calibration aborted, temperature
measured value varies.
Reasons: sensor too old, sensor
occasionally dry, temperature of
calibration solution not constant.
1. Check sensor.
2. Regulate calibration solution
temperature.
