Honeywell MultiRAE Series - Single-Sensor and Span Calibration

After a timer countdown, the zero calibration is done. The LCD displays the sensor names and
tells you whether each calibration passed or failed, followed by the sensor readings.
Note: You can abort the calibration at any time during the countdown by pressing [N/-].
Single-Sensor Zero Calibration
Select the sensor and then start the calibration by pressing [Y/+]. You can abort the procedure
anytime by pressing [N/-].
Span Calibration
This procedure determines the second point of the sensor calibration curve for the sensor.
Note: When a manual calibration is performed, the readings shown are in the equivalent units
of the calibration gas, and not the measurement gas.
