mV Parameter
pH 50 VioLab; PC 50 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 (Redox Potential)
pH 50 VioLab; PC 50 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.
ORP Parameter Setup
In measure mode press the key
to access the SETUP menu.
Use the directional keys to move to ORP SETTINGS P2.0 and access the menu by pressing the key
.
Move with keys
and
to select the program to access.
The table below shows the Setup menu structure for the ORP parameter; for each program there are the
options that the user can choose and the default value:

P2.6 Calibration data
Access this menu to get information on the last calibration performed. The screens with the sensor offset
value and the temperature at which the calibration was performed will scroll on the display.
P2.8 Reset of the ORP Parameter
If the instrument does not work properly or incorrect settings have been made, confirm YES with the key
to return all the parameters of the ORP menu to the default settings.
P2.9 Temperature calibration
All the instruments in this series are pre-calibrated for a correct temperature reading. However, if a
difference between the measured and the real one is evident (usually due to a probe malfunction), it is
possible to perform an offset adjustment of +5 °C.
Use the keys
and
to correct the temperature offset value and confirm with
