TP error
ISE error

Cause Remedy
During calibration:
– Calibration standards do
not have the correct
temperature (max.
± 2 °C
temperature difference)
– Adjust the temperature of
the calibration standards
During measurement:
– Test sample does not
have the correct
temperature
(max.
± 2 °C temperature
difference from calibration
temperature)
– Adjust the temperature of
the test sample
Cause Remedy
During calibration:
– Calibration standards are
too close to each other
IU

- U
1
I ≤ 5 mV
IU
3
- U
2
I ≤ 5 mV
– Use other calibration
standards
Cause Remedy
After two-point calibration:
– The highest or lowest
calibration standard was
used as the second
calibration solution.
– Cancel the calibration
(the present two-point
calibration is retained)
