3.1.2 Starting pH calibration
1. Turn the meter ON. If the meter is not in the pH measurement
mode, press EXIT and press >/CAL to select pH/Temp. The
mode selected will flash. See Figure 13. Press ENTER to
confirm selection. The meter is now in pH measurement mode.
See Figure 14.
2. Rinse the electrode in deionized water or rinse solution. If using
the ATC function with a separate temperature probe, rinse the
temperature probe as well. Do not wipe the pH electrode or
temperature probe dry. Wiping the probes causes static, and
will create calibration and measurement instability.
3. Select pH buffer and pour into a clean container.
4. Dip the electrode and ATC probe into the calibration buffer. The
end of the probes must be completely immersed into the
sample. Stir probes gently to create a homogeneous sample.
5. Press >/CAL to enter the pH calibration mode. The display
flashes Cal Mode Activated, Please wait....
See Figure 15. The meter is now in pH calibration mode.
The meter automatically recognizes the buffers in the set you have selected in the SETUP mode. If you wish to change
the buffer set selected, see Section 10.2.2, Program pH Buffer Setup: P1.0 in the pH/Temp setup mode (page 30).
If your meter is set up for standard buffers (USA, NIST, Bf1, Bf2), proceed to Section 3.1.3: Standard pH buffer
calibration (page 13). If your meter is set up for custom buffers, proceed to Section 3.1.4: Custom pH buffer calibration
(page 14).
