• The meter automatically skips the buffer used for the first calibration point to avoid
erroneous procedure. A difference of at least 1.5 pH unit is required between the two
buffers used for the offset and slope calibration: once calibrated at either pH 7.01 or
6.86, the instrument automatically ignores the other value for the second point (same
for pH 10.01 and 9.18).
• During calibration, the secondary LCD shows the selected buffer value; press the
RANGE key to display the buffer temperature.
• To clear a previous calibration and return to the default values, press CLR at any time after
entering the calibration mode. The LCD will show “CLr CAL” for one second, and then will
return to normal measurement mode.
