• Composition of the setup Menu for the ORP parameter
P2.6 Calibration Data
Access this menu to get information on the last calibration performed. The following screens will
automatically scroll on the display:
• First screen: CALIBRATION DATE and TIME.
• Second screen: OFFSET value of the electrode expressed in mV.
• Third screen: TEMPERATURE at which the calibration was performed.
P2.7 ORP calibration deadline
Access this menu to set a calibration deadline; this option is fundamental in GLP protocols.
• By default, no calibration deadline is set; use the directional keys to select HOURS or DAYS and access
with key . Use the directional keys to change the number that appears in the centre of the
display, entering the hours or days that must elapse between two settings, and confirm with key .
• If a calibration deadline is set, the icon is shown on the display in measure mode.
• When the calibration deadline is activated, the instrument prevents further measurements.
The error icon and the icon representing the calibration deadline flash on the display.
The string “MAKE A NEW CAL” invites the user to perform a new calibration of the pH sensor to be
able to work again.
Press the key to start the calibration.
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.
IMPORTANT: The factory reset of the parameters does not delete the stored data
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 .
