1. Measurement with ATC/Temp probe in the pH mode.
1.1 Removed the pH electrode and rinse with distilled water and
immerse it in the sample to be measured and the ATC anniciator
(model 6250) or green color LED lamp (model 6219) will
be on (Per Figure 3). The pH unit , ATC, STAND and SLOPE
indicators are on .
1.2 The display will track the pH value as sensed by the pH
electrode and the ATC/Temp probe. Allow sufficient time for
the display to stabilize. The instrument will display the pH
value of the sample at the displayed sample temperature.
If Er5 is displayed, the pH value measured is out of the
-2.000 to 16.000 pH range.
2. Measurement with manual temperature compensation in the pH
mode
2.1 Connect the pH electrode to the connector of the instrument.
Refer to Figure 2.
2.2 Press the MODE key enter into pH mode, the pH , STAND, SLOPE
indicators is on and the MANUAL anniciator (model 6250)
or red color LED lamp (model 6219) are on . (Per Figure 3)
2.3 Rinse the pH electrode with distilled water and immerse it in the
sample to be measured.
2.4 Use the UP and DOWN keys to set the sample solution's
temperature.
2.5 Allow sufficient time for the display to stabilize. The instrument will
display the pH value of the sample at the set
sample temperature.
If Er5 is displayed, the pH value measured is out of the -2.000 to
16.000 pH range.
