Step
Bump Testing Using Calibration Gas Cylinders
1
For remote sensor configurations, remove the enclosure lid of
the gas detector (not in an exhaust area). For integrated
sensor configurations, the calibration cup needs to be
mounted on enclosure.
2
Connect a voltmeter to 0V and VS to monitor sensor
response.
3
Expose the sensor to gas from the cylinder. Use a plastic
hose/hood to direct gas to the sensor. A response of above
80% of full range (as per rating label) is acceptable.
6.3. Checking and Setting the Zero Setting
Checking and setting the zero setting may be required upon initial
installation. Ensure the unit was powered up for at least 24 hours before
making any adjustment
Tools Required:
•
A voltmeter (crocodile clips are recommended)
•
Factory standby (zero) voltage from side label
•
Screwdriver
Step
Checking and Setting the Zero Setting
1
Ensure that the IAM-100 is stabilized (on for more than
24 hours)
2
Connect the voltmeter between 0V and VS.
3
Compare the reading of the voltmeter to the factory standby
voltage. Adjust P1 as necessary until the voltmeter reading
matches the factory standby voltage settings. If necessary
adjust to ambient conditions.
