BA61101/08.00/Pla/MLP5-E2
Calibration: Calibration data outside of
admissible ranges.
Admissible slope range:
AR TP
-62 mV ... -50 mV
Possible cause / Action:
- Wrong buffer solutions
/ Change buffer solutions, see
set buffer combination
- Old buffer solutions / Change buffer
solution, see preservability date
- Old electrode / Change electrode
- Short circuit / Change electrode or
repair meter
- Wrong temperature value (only with
measurements without temperature
probe)
/ Set correct temperature value
Admissible asymmetry range:
-30 mV ... +30 mV
Possible cause / Action:
- Wrong buffer solutions
/ Change buffer solutions, see
set buffer combination
- Old buffer solutions / Change buffer
solution, see preservability date
- Old electrode / Change electrode
- Contaminated junction
/ Clean junction
- Wrong temperature value (only with
measurements without temperature
probe)
/ Set correct temperature value
