Calibration With Ion-Selective Electrodes - XS Instruments Revio Manual De Instrucciones

Last calibration data
Access this menu to get information on the last calibration performed.
Due calibration
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
hours that must elapse between two settings and access with key
• When a calibration deadline for a parameter is set, the icon

• When the calibration reaches the set deadline, it will no longer be possible to perform
measurements for that parameter until the calibration is renewed or the deadline is deactivated.
• The error icon

Restore Factory Default
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.

• Calibration with ion-selective electrodes

Example: two-point calibration
• Access the Setup ISE menu
and in Select low standard parameter the more diluted solution: 0.010 (mg/l).
The device automatically multiplies the lower standard entered by the user by a factor of 10, to identify
the other points of the calibration line.
Connect the appropriate ISE electrode for the ion you want to determine to the connector for
•
pH/mV/ORP (green measuring channel).
Important: if the ISE electrode is not combined, it necessary to connect the specific reference
electrode. For any filling electrolytes of the reference electrode and for any iconic strength adjusters
(ISA) refer to the user manual of the ISE electrode.
