8.pH Calibration.
Fig. 15 Calibration buffers
Take out the sensor. You may not place the nut, because the analyzer do not
sucks during calibration.
Serve for pH meter’s calibration. For this purpose 2 sample buffers are used,
shown on the display as
Low buffer (for example 3.00 pH) and High buffer
(for example 7.00 pH). Follow the procedure:
Please, use this procedure only if you have enough calibration buffers as they
could not be used more after the procedure. In case you have no enough
buffers, place the pH probe in a separate vessels with calibration buffers and
water near the analyzer as per Fig. 14.
1. Start the
Calibration menu.
2. Put the probe in the buffer, corresponding to the isopotential point of the
probe (in most of the cases it is 7.00).
