Orp Parameter (Oxide-Reduction Potential); Orp Parameter Setup - Xs Instruments 70 Serie Manuel D'utilisation

ORP Parameter (Oxide-Reduction potential)

pH 70 Vio; PC 70 Vio
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; 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 relevant purchase. The instrument can correct the sensor offset by + 75 mV.
 ORP parameter Setup
 In measure mode press the key
 Use the directional keys to move to ORP SETTINGS P2.0 and access the menu by pressing the key
.
 Move with the keys
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 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

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.
