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.
pH1 Cal at:
Sensor >
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.

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 ORP test solution. Allow suffi cient time for sensor output to
stabilize, then enter value. Maximum offset allowed: ±2900 mV.
Place sensor in any buffer that is different by at least 30 mV from Std value, then enter
value. Maximum offset allowed: ±2900 mV.
If ORP~ Cal at Instrument is selected, reset Standard and Slope to factory calibration.
