NOTICE
To prevent the corruption or loss of data and/or software and/or
firmware, do not deactivate the equipment while performing datalog
transfers, bump tests, calibrations or other operations.

Connect Calibration Gas
1. Connect a demand flow regulator to the calibration gas cylinder.
2. Use the quick-connect fittings and calibration gas tubing
to connect the calibration gas cylinder to the gas.

Bump Test
A bump test is a procedure that confirms a detector’s ability to respond to the target gases by exposing the detector to gas concentrations that exceed its alarm setpoints.
If AutoBump on Insertion is set using PC configuration software, then the bump test starts automatically when IntelliDoX recognizes the detector. If AutoCal on Overdue Sensors is enabled and if calibration is also due, then no bump test is performed. Instead, calibration starts automatically when the detector is recognized.

1. Insert a detector.
2. Press and on the keypad to move to Bump test my detector on the IntelliDoX user menu.
3. Press to select Bump Test. The LCD screen background changes to yellow and the bump test progress screen is displayed.
4. The bump test begins. Test sequence progress screens are displayed while the tests are performed.
5. If AutoDownload Datalog is set using PC configuration software, detector data logs are automatically transferred to IntelliDoX.

Bump Test Pass
When the bump test is successful, the LCD screen background changes to green and the Bump test passed message is displayed. Alarm response and sensor response test items are checked.

Press to return to the IntelliDoX user menu.

Bump Test Fail
When the bump test fails, the LCD screen background changes to red and the Bump test failed message is displayed. Failed alarm response and/or sensor response test items are marked with.

If the AutoCal on Failed Bump is set using PC configuration software, calibration automatically begins.

Calibration
Calibration is a two-step procedure that determines the measurement scale for the detector’s response to gas. In the first step, a baseline reading is taken in a clean, uncontaminated environment. In the second step, the sensors are exposed to known concentrations of gas. The detector uses the baseline and known gas concentrations to determine the measurement scale.

Calibration Guidelines
1. Calibrate only in a normal environment that is 20.9% O2 and free of hazardous gas. Do not operate the docking module in a hazardous area. Failure to adhere to this guideline can result in possible personal injury and/or property damage.
2. Use only premium grade calibration gases and cylinders that are approved by Honeywell, and supplied by Honeywell or an authorized distributor. The calibration gases must meet the accuracy of the detector. For more information, refer to the User Manual.
3. Do not use a gas cylinder beyond its expiration date.
4. All calibration cylinders must be used with a demand flow regulator and must meet these maximum inlet pressure specifications. Disposable cylinders: 000 psig/70 bar, refillable cylinders: 03000 psig/207 bar
5. Do not calibrate the detector during charging or immediately after charging.
6. Calibrate the sensor if ambient gas readings vary during startup.
7. Calibrate a new sensor before use. Allow the sensor to stabilize before starting calibration.
8. Used sensor: wait 60 seconds
9. New sensor: wait 5 minutes
10. When calibrating the same gas detector multiple times, wait 10 minutes between calibrations to allow the sensor to stabilize.
11. If a certified calibration is required, contact Honeywell or an authorized distributor.

Calibrate a Detector
If AutoCal on Overdue Sensors is set using PC configuration software and sensors are overdue, then calibration starts automatically once IntelliDoX recognizes the detector.
1. Insert a detector.
2. Use and to move to Calibrate my detector on the IntelliDoX user menu.
3. Press to select Calibrate my detector. The LCD screen background changes to yellow and the calibration progress screen is displayed.
4. Calibration begins. Progress screens are displayed while the tests are performed.
5. If AutoDownload Datalog is set using PC configuration software, detector data logs are automatically transferred to IntelliDoX.#

Calibration Pass
When the calibration is successful, the LCD screen background changes to green and Calibration passed is displayed. Alarm response and sensor response test items are checked.
Press to return to the IntelliDoX user menu.

Calibration Fail
When the calibration fails, the LCD screen background changes to red and Calibration failed is displayed. Failed alarm response and/or sensor response test items are marked with .
