4. Operation
4.11. Measurement with ion selective electrode
Curve number 1
sensION
™
+
MM340
can store in memory up to 4 calibration
curves for each channel .
Measurement by stability
It is the standard measurement mode of
MM340
. See
details in “pH measurement”, page 10 .
Criterion of “rapid” stability: variation < 0 .5 mV in 6 s .
Criterion of “standard” stability: variation < 0 .1 mV in 10 s .
Criterion of “strict” stability: variation < 0 .05 mV in 10 s .
It is highly recommended to apply the same criteria to measure
and calibrate .
Measurement in continuous or by time
See details in “pH measurement”, page 10 .
Note:
Anyone of the 2 channels can measure pH, mV or ISE .
The measurement units are selected in System .
