9.2.2. PERFORMING A MANUAL CALIBRATION CHECK

Note If the ZERO or SPAN menu buttons are not displayed, the measurement
made during this cal check is out of the allowable range allowed for a reliable
calibration. See Section 11 for troubleshooting tips.

9.2.3. PERFORMING A MANUAL CALIBRATION

The following section describes the basic method for manually calibrating the
T803.
If the analyzer’s reporting range is set for the DUAL or AUTO range modes, a
step will appear for selecting which range is to be calibrated: RNG1 (LOW) or
RNG2 (HIGH).
Each of these two ranges MUST be calibrated separately.
