•
The icon on the display
indicates that the connection was successful.
•
If the calibration is satisfactory (see the calibration data in menu P.1.6), the electrode is ready to start
the measurements. Otherwise, recalibrate the electrode; the data will be updated automatically.
•
The DHS electrode calibrated with a pH 70 Vio or PC 70 Vio device is ready to be used on any pH meter
enabled for DHS recognition and vice versa.
•
When the electrode is disconnected, a message on the display informs the user of the deactivation
of the sensor; the instrument regains its previous calibration and no data is lost!
•
The DHS electrode does not require batteries and if it is used on pH meters that are not enabled to
recognize the chip, it works as a normal “analog” electrode.
•
Errors during calibration
•
NOT STABLE
:
The button
was pressed with still unstable signal. Wait for the icon
to appear
to confirm the point.
•
WRONG BUFFER
: The buffer is polluted or not part of the recognized families.
•
SLOPE OUT OF RANGE
: The slope of the sensor calibration line is out of the acceptable range 80 - 120%.
•
CALIBRATION TOO LONG
:
the calibration exceeded the time limit: only the points calibrated up to that
moment will be kept.
mV Parameter
pH 60 VioLab; PC 60 VioLab
•
In measure mode press the key
and move to the mV parameter indicated by the icon
.
•
The display shows the measurement in mV of the pH sensor.
•
The scrolling on the display of four red bands
means that the measurement is not stable yet.
•
Consider the measurement truthful only when the stability icon appears
.
Note
: This measurement is recommended to evaluate the sensor efficiency
ORP Parameter (Oxide-Reduction potential)
pH 60 VioLab; PC 60 VioLab
ORP sensors can be used on this series of devices to measure the Oxide-Reduction Potential.
Connect the Redox electrode to the BNC type connector marked in green; instead, if necessary, connect the
temperature probe to the RCA / CINCH Temp connector always marked with a green background.
It is possible to calibrate the sensor offset by performing automatic calibration on a predefined point. The
instrument automatically recognizes the
Redox solution 475 mV / 25 °C
; contact the local distributor to
proceed with the purchase.
The instrument can correct the sensor offset by + 75 mV.
