8.3 Calibration
C A U T I O N
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.
C A U T I O N
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and
national regulations.
Calibrate the sensors before initial use, at regular intervals and after sensor maintenance or
modifications. Periodically, do a calibration check to make sure that measurements are still within
tolerance range.
Refer to the Hydrolab Operating Software Manual for instructions on how to do the tasks that follow:
• Start a sensor calibration.
• Start a sensor calibration check.
• Set the calibration mode.
• Select the measurement units shown during calibration and calibration checks.
• Look at the calibration history.
To look at the Hydrolab Operating Software Manual, start the Hydrolab Operating Software, click
Help and select Hydrolab Operating Software Help.
When a calibration or a calibration check is started, the step-by-step instructions for the sensor show
on the display.
