SENSOR: Select to perform calibration at the sensor via 2750 EasyCal.

INSTRUMENT: Select to perform calibration at the 8900 via the steps below.

If Cal at Instrument is selected, the following menu items appear:

Place sensor in any pH buffer. Allow sufﬁ cient time for sensor output to stabilize, then

enter value. Maximum offset allowed: ±1.3 pH.

Place sensor in any buffer that is different by at least 2 pH units from Std value, then enter

value. Maximum offset allowed: ±1.3 pH.

Adjust the temperature measurement from the pH sensor to match a reliable reference.

Maximum offset allowed is ± 20 °C

If pH~ Cal at Instrument is selected, reset Standard, Slope and Temperature to factory

calibration.
