CALIBRATION BUFFER DIRECT SELECTION
This feature allows to set a user-defined calibration point, in order to perform calibration
at a point different from the memorized standards.

TEMPERATURE CALIBRATION
The controller is factory calibrated for temperature. However, the user may also perform
a one point temperature calibration. This procedure is to calibrate the offset only; the
slope will remain as factory calibrated.
• Prepare a beaker containing a solution at a given temperature inside the range of
the meter.
• Use a Checktemp or a calibrated thermometer with a resolution of 0.1° as a reference
thermometer.
• Immerse the temperature probe in the beaker as
close to the Checktemp as possible.
• Press and hold first CFM and then CAL to enter the
temperature calibration mode.
• Execute the password procedure.
• Select code 1 via the arrow keys for temperature calibration and confirm with CFM.
