While in Measurement mode press the [CAL] key. If the display prompts you to enter
the calibration security code, press the m or . key to set the calibration security
code, then press the [ENTER] key to confirm the calibration security code.
Press [ENTER] to select the CONDUCTIVITY CALIBRATION SUB FUNCTION.
A flashing "H" (alternating with "A" or "B" to show the channel being calibrated for
multi-channel devices) in the top left hand corner shows the ongoing calibration
process.
Choose the compensation mode by using the m or . key.
Press [ENTER] to confirm the compensation mode.
Select 1 POINT instead of 2 POINT CALIBRATION by pressing the . key once followed
by the [ENTER] key.
CAUTION: Rinse sensors with a high-purity water solution before every calib r ation to
prevent contamination of the reference solutions.
Place the electrode in the reference solution.
Enter the value of Point 1 and press the [ENTER] key.
