If the instrument does not work properly or incorrect calibrations have been performed press Yes with
key to return all Ion parameters to the factory default setting.
IMPORTANT: The factory reset of the parameters does not delete the stored data.

diluted standard: 0.010
The device automatically multiplies the lower standard for a factor by a 10 to locate the other
points in the calibration curve.
• Connect the appropriate ISE electrode to the connector for pH/mV/ORP (yellow/blue).
Important: If the ISE electrode is not combined, it is necessary to connect the specific reference electrode.
Refer to the ISE electrode manual for any reference electrode filling electrolytes and for any ionic strength
adjusters (ISA).
