4.3. Factory configuration

+
The sensION is an instrument with 2 measurement
™
MM340
channels to measure pH, mV or concentration with a selective
electrode . The factory configuration is as follows:
Channel 1
Units: pH
Resolution 0 .01 pH .
Measurements: By stability with standard criterion .
In continuous pressing twice the key
Calibration in 1, 2 or 3 points, with technical buffers .
Calibration frequency, every 24 hours .
Channel 2
Units: ISE
Measurements: By stability with standard criterion .
In continuous pressing twice the key
Curve number 1 .
Five points calibration, units mol/l .
Standards: 0 .00001, 0 .0001, 0 .001, 0 .01, 0 .1 .
Common to Channel 1 and 2
Automatic sample coding .
Data sending, report type, etc . in accordance with the start up
configuration .
Re-programming
To perform any modification in the default programming, for
example measuring units of the channels, different measuring
modes, calibration with other type of buffers, etc . see corre-
sponding chapters .
Stirrers
In one standard instrument, Channels 1 and 2 will work with
stirrer number 1 (ST1) .
If you have a 2nd stirrer it must be connected to Channel 2 (ST2) .
Afterwords it must be configured, see System page 17 .
The second stirrer will be assigned to Channel 2 .
