General Calibration Notes
When calibrating a detector...
s ALWAYS refer to the product manual first!
s YOU MUST use the proper Calibration Cap when calibrating
s NEVER use the Weather Protection Housing or other accessories for calibration – use for Bump Test only
s YOU MUST use the proper flow rate for the sensor type used in the transmitter
Zero Calibrations
Zero calibration is a recommended procedure that should be performed periodically to improve the performance
of the sensor. This is particularly important when the sensor is operating outside of normal environmental
conditions.
s ALWAYS use Zero Air calibration gas or reference device (such as a calibrated portable) when doing
Zero Calibrations
Bump Test
A bump test is not intended to be an accurate calibration, but is used as a confidence check to ensure that
the gas detection system is functional. Some of the target gases are difficult to handle therefore bump testing
often makes use of cross sensitivities so that more convenient gases can be utilized.
s The bump test is a functional check only.
s Consult your local guidelines and/or product manual for recommended best practices
Span Calibration
Bump test versus calibration
Factory calibration is performed in a controlled environment with certified reference devices providing a high
level of accuracy. Field span calibrations are subject to external influences such as background concentrations
of gas and airborne contaminants that may affect the accuracy of a field calibration.
s ALWAYS use the target gas for calibrations when possible otherwise contact the manufacture for approve
Cross-Calibration gas and predicted response to concentration (some gases can damage sensors)
Most products are calibrated to 50% FSD (Full Scale) while others may require other values – refer to
product manuals or contact the manufacture for details.
4-20mA Output Adjustment
s It may be required to adjust the 4-20 mA output based on the installation. See the respective product
manual for specifics.

VA201T/VA201M Calibration Procedure
IF YOUR TRANSMITTER WAS PURCHASED BEFORE APRIL 1, 2004, CONTACT TECHNICAL SUPPORT
LINE AT 1-800-563-2967
1. Warm-Up Period
Turn the unit on for a minimum of five (5) minutes when battery back-up sensor board is included.
Check Calibration Information table for specific warm-up time.
2. Connecting the Hardware
Plug the voltmeter probes in the unit and adjust it to read VDC.
Plug the calibration adaptor into the gas sensor inlet.
Always plug the calibration adaptor to have the holes in a vertical position.
Always connect the tubing in the lower hole.
Screw the regulator to the calibration span gas cylinder.
Connect the regulator outlet to the calibration adaptor with the 1/8 I.D. polymer tubing.
3. Adjusting the Zero (if required)
If you suspect the presence of the target gas, inject zero gas at the specified flow rate for a minimum
of 1 minute prior to adjusting the potentiometer.
Adjust the zero potentiometer to read -35 mV.
This must be achieved in a well ventilated area where there is no presence of the target gas.
CAUTION :
For all Q2 except CO detectors bought after April 25, 2005, do the following steps:
Adjust the zero potentiometer to read 10 mV.
Very slowly, adjust the zero potentiometer to read 0 mV. Be careful do not go under 0 mV because the negative
voltage won’t be displayed.
4. Adjusting the Span
Turn on the regulator and inject span gas at the specified flow rate.
The span gas is now flowing into the unit.
After 2.5 minutes, the voltmeter readings should be stabilized.
