PREPARATION
1. Ensure that the unit to be calibrated is properly installed and has been operating
for at least one hour.
2. Use only Veris Industries calibration kit model AA01. Perform the zero calibration
with nitrogen gas. Use a flow regulator to limit gas flow to <0.25 liter/minute.
Exceeding this flow rate may cause calibration errors.
SETUP
1. Connect tubing to the regulator and screw the regulator on the gas bottle.
2. Remove the front cover from the unit and locate the plastic barb fitting and the
menu push-button. A label indicating push-button functions is located inside
front cover plate.
