Calibration
CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the
personal protective equipment appropriate to the chemicals that are handled. Refer to the
current safety data sheets (MSDS/SDS) for safety protocols.
Calibrate the tester before initial use and when:

• Results are not accurate
• "?" shows next to the calibration icon on the pH screen
Before initial calibration and after dry storage, soak the sensor for several minutes in the
sample or a pH buffer.
Calibrate the parameters shown in Table 3 with the:
• Auto calibration procedure
• Custom calibration procedure
The number of calibration standards measured (calibration points) depends on the
calibration procedure. Refer to Table 3.
