A.

Zero Calibration:

1.

In clean gas-free air, momentarily hold magnet over

ZERO CA

L switch until LCD

display shows

When zero calibration is complete, the transmitter will return to normal operation to
provide meter readings.

Note:

If ambient air is not known to be gas-free, apply

zero air

(cylinder) using calibration

Cup
