Note: The meter will automatically skip the buffer that was used for

the first calibration. pH 6.86 and pH 7.01 as well as 9.18

and 10.01 pairs of buffer solutions are also considered too close

to allow an adequate two-point calibration. Consequently,

after calibrating in one of the pair, the meter will also skip the

other buffer.

Note: During calibration, the secondary LCD displays the selected

buffer value.

Press RANGE and the temperature of

the buffer will be displayed during cali-

bration.
