6 Testing

Using a certified gas with a concentration other than the one listed for this detector
when conducting a calibration verification test (bump test) will produce inaccurate
readings. This means that higher levels of the gas being monitored may be present and
could result in overexposure. For proper use, see supervisor or User manual, or
contact Technical Support at 1-844-325-3050.
6.1 Testing
6.1.1 Operation Test
Detectors are factory calibrated for the specific gas required by the customers. Testing should be carried
out by using a gas mixture in the appropriate range, along with our calibration kit. Accuracy and bump
test procedures of gas detectors are required by code. These standards give guidance on the selection,
installation, use and maintenance of gas detectors intended for use in industrial and commercial
applications. The standards require accuracy and bump testing as well as recording of the performed
checks and it defines that all gas detectors should undergo periodical operational testing according to the
manufacturer's specifications. Test results should be properly recorded.

6.2 Calibration and Test Kits

The following steps must be performed when conducting a calibration verification test
(bump test) to ensure proper performance of the monitor. Failure to do so may
adversely affect product performance.
•
When performing a calibration verification test (bump test) only use certified
calibration gas at the required concentration level.
•
Do not test with expired calibration gas.
•
Do not cover or obstruct display or visual alarm cover.
•
Ensure sensor inlets are unobstructed and are free of debris
Failure to follow instructions outlined in this user manual can result in sickness or
death.
•
When performing a calibration or calibration verification test (bump test) only use certified calibration gas at the
required concentration level. Do not calibrate with expired calibration gas.
•
If the instrument cannot be calibrated, do not use it until the reason can be determined and corrected.
•
Do not cover or obstruct display or visual alarm cover.
•
Ensure sensor inlets are unobstructed and are free of debris
