MAN_CAL 4: buffer out of tolerance
The buffer value found is outside the tolerance range (± 30 mV) of the
standard buffer given. Check sensor and buffer solution.
MAN_CAL 5: same buffer
The same buffer value has been found twice in succession. The buffer solu-
tion has probably not been changed.
MAN_CAL 6: temperature out of range
During temperature measurement an invalid value has been found. Check
that the temperature sensor is functioning properly.
MAN_CAL 7: temperature out of tolerance
For a correct calibration all buffer solutions in a series must have approxi-
mately similar temperatures. A temperature has been found which is outside
the tolerated scatter range of 2°C.
MAN_CAL 8: meas. value overrange
A potential > 2000 mV has been measured. Check the sensor.
MAN_CAL 9: meas. value underrange
A potential < -2000 mV has been measured. Check the sensor.
MAN_CAL 12: max. number of buffers reached
The buffer list is full. No further buffers can be measured.
MAN_CAL 13: check buffer type and list
The newly entered buffer type does not match the corresponding buffer in
the table. Correct the buffer type or delete the whole calibration.
MAN_CAL 14: missing temperature sensor, interface 'X'
The necessary temperature sensor has not been connected.
MAN_CAL 15: invalid standard buffer value
The measured buffer value cannot be allocated to any standard buffer of the
given manufacturer or type.
