PRODUCT IDENTIFICATION

AA01 CO

Calibration Kit

PRODUCT OVERVIEW

The AA01 CO

calibration accessory is designed for eld calibration of any CO

sensor

produced by Veris Industries, regardless of age. It comes complete with calibration

gas, a gas regulator, tubing, and ttings. The calibration process normally takes

about 5 minutes.

In general, Veris CO

sensors use a time-weighting factor, which retains the lowest

concentration of CO

measured in a selectable time period. That information is then

used to calculate the ambient or base level CO

concentration. This calculation allows

a CO

sensor to improve its accuracy over time.

To use this instruction guide, rst identify the shape of the CO

sensor inside of your

Veris device (rectangular or pear), and then turn to the applicable section of this

instruction manual for the instructions.

Note: For all calibrations, when connecting the gas regulator assembly to the gas

bottle, verify there is at least 10 lbs of pressure remaining in the bottle. The CO

sensor cannot be calibrated correctly with less than 10 lbs.

ENVIRONMENTAL SENSORS INSTALLATION GUIDE TM AA01 CO2 Calibration Kit PRODUCT OVERVIEW The AA01 CO2 calibration accessory is designed for field calibration of any CO2 sensor produced by Veris Industries, regardless of age. It comes complete with calibration gas, a gas regulator, tubing, and fittings. The calibration process normally takes about 5 minutes. In general, Veris CO2 sensors use a time-weighting factor, which retains the lowest concentration of CO2 measured in a selectable time period.

INSTALLATION GUIDE AA01 TM FOR ANY CO2 DEVICE WITH RECTANGULAR SENSOR CX/CWL/CDL CALIBRATION PREPARATION 1. Press ENTER to enter configuration mode. 1. Ensure that the unit to be calibrated is properly installed and has been operating for at least one hour. 2. Press ENTER repeatedly until the CO2 CAL menu option appears on the display. 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.

INSTALLATION GUIDE AA01 TM FOR CDL/CWL DEVICE WITH PEARSHAPED SENSOR 1. Remove cover and connect the gas cylinder hose to the plastic port located on the sensing module. Connect only one sensor to the calibration gas cylinder at a time. 2. Start flowing nitrogen gas (0 ppm CO2). Use a flow rate of 0.3 to 0.5 liter/minute.
