If you do not want to restore the initial calibration, choose
no
before pressing the
CAL
key.
Otherwise, choose
YES
and press the
CAL
key. The offset returns to 0.0 mV.
3.2.4. MEASUREMENTS
Once the calibration is over, the electrode is ready to make measurements.
Between measurements, the electrode must be rinsed and dried. When you have finished using it, put it back in its storage
bottle.
For each measurement, wait for the measurement to stabilize.
3.3. RECORDING THE MEASUREMENTS
A short press on the
MEM
key records the measurement with the date and time. The MEM symbol is displayed briefly.
It is not possible to record a single measurement while the instrument is already recording
.
A long press on the
REC
key starts or stops a recording session. The REC symbol remains displayed for the duration of a
recording session. Auto off is deactivated (this means that the instrument is in permanent mode) and the
P
symbol is dis-
played.
If the
REC
symbol flashes, a recording session has been programmed and is pending.
Before starting a recording session, make sure that the battery life is sufficient, or else connect the instrument to an external
power supply on/to a wall outlet using a micro USB cord.
When the memory is 90% full, the
MEM FULL
symbol blinks. When the memory is full, the
MEM FULL
symbol stops blinking
.
To see the records, you must use a PC and install the Data Logger Transfer software (see §
4).
