Bump Testing And Calibration

To ensure greatest accuracy and safety, only bump test and calibrate in a fresh air environment.
The monitor should be calibrated every time it does not pass a bump test, but no less frequently than
every six months, depending on use and exposure to gas and contamination, and its operational
mode.
• Calibration intervals and bump test procedures may vary due to national legislation.
• Honeywell recommends using calibration gas cylinders containing the gas that is appropriate to
the sensor you are using, and in the correct concentration.
When a bump test is done manually, the instrument makes a pass/fail decision based on sensor
performance, but the user still has the responsibility to make sure all the alarms are enabled and
functional.

Bump (Functional) Testing

The same gas is used for a bump test as for calibration. A constant-flow regulator producing 0.5 liters
per minute should be used, and the calibration adapter must be installed on the diffusion model of the
RigRat. The instrument must be connected to a cylinder of calibration gas with supplied tubing.
Note: If LEL% and VOL% sensors are installed always bump test the LEL% sensor first.
1. Turn on your RigRat by pressing and holding the button, and allow the instrument to boot up
fully until the main measurement screen with sensor names and readings is shown.
Important! Make sure all of the instrument's sensors have warmed up before performing a bump
test. The instrument will take the time to warm up the sensors prior to enabling access to bump
test menus. You can tell a sensor has warmed up if you see a reading next to it name on the
display. If it has not warmed up, you see three dashes ("---") next to it.
2. Diffusion: Install the calibration adapter on the RigRat by setting it on over the sensors and
pressing until it is snug against the surface of the instrument.
Pumped: Connect tubing from the filter's inlet to the regulator on the gas cylinder.

3. To start the bump test, hold the button for 3 seconds at the "Bump Due" screen.
4. The 3-color LED and buzzer will activate (this tests the alarms).
5. Hold the button for 3 seconds if the audible and visible alarms are fully functional. Otherwise,
press the button once to confirm that you understand there are faults.
