If the “Pnt” option is selected, the new calibration point overrides an
existing one. The adjacent slopes will be reevaluated.
If the “OFFS” option is selected, an electrode offset correction is performed.
The adjacent slopes will remain unchanged.
• Proceed as described in “TWO-POINT CALIBRATION” section.
• Press CAL after the first calibration point was confirmed. The
instrument will memorize the one-point calibration data and return
to measurement mode.
Notes: • To clear calibration parameters for all uncalibrated buffers
starting with current buffer, press CLR. The calibration
will continue from the current point. If this procedure is
performed while calibrating in the first calibration point, the
instrument returns to measurement mode.
• Press RANGE to toggle between pH buffer
and temperature reading.
