7. Press the
[MODE]
key momentarily to move from one
sensor location to the next one. Repeat Step 7 until all
of the sensors which need to be calibrated during
multiple sensor calibration are selected. Press and hold
the
[MODE]
key for 1 second to save the new sensor
selection.
8. The display shows “Save?” To confirm the new
selection, press the
[Y/+]
key to accept the change and
continue on with Step 2. Press the
[N/-]
key or the
[MODE]
key to discard the change and to continue on
with Step 2.
Cross Sensitivity:
Some sensors may show cross
sensitivity to other gases. Therefore, it is important to
choose the gas mixture carefully for the multiple sensor
calibration to avoid erroneous calibration due to cross
sensitivity. For example, some VOC gases are known to
cause erroneous readings by the CO sensor. In general, it is
recommended to calibrate the two toxic sensors,
combustible and oxygen sensor with a bottle of mixed gas
using the multiple sensor calibration procedure and to
calibrate the PID sensor with a bottle of a single VOC gas.
