Calibration
error
messages
If errors occur during calibration, or if the determined
sensor data are outside the valid range, an error message
appears (
ERROR 6, ERROR 11
).
ERROR 6
The cell constant lies outside the permissible range
< 0.01 cm
–1
or > 199.9 cm
–1
.
Possible causes:
• No sensor connected during calibration
• Wrong calibration solution
• Sensor not immersed far enough in calibration solution
ERROR 11 The calibration was canceled after approx. 2 minutes,
because the drift was too large. This message only appears
briefly during calibration.
Possible causes:
• Sensor defective or dirty
• Sensor cable insufficiently shielded or defective
• Strong electric fields influence the measurement
• Major temperature fluctuation of the calibration solution
• Calibration solution unstable
• Conductive connection between potential to ground, PC,
meter and measured medium
ERROR 14 If the clock has not been set, e.g. after battery replacement,
this error message is displayed. To clear the message, set
ERROR 15 If errors occur during transmission via the RS 232 interface,
this error message appears.
To eliminate the error message, switch the meter off and
then on again. Should the error message occur again, check
the settings in the Configuration menu.
Possible causes:
• Wrong transmission rate (baud rate) set (see page 17)
• Error during transmission
• Wrong data format (see page 17), e.g. parity bit
