Prior to each day’s use, every gas detection monitor should be bump tested to confirm the response of
all sensors and activation of all alarms by exposing the monitor to a concentration of target gas that
exceeds the low alarm set point. A bump test is also recommended if the monitor has been subjected to
physical impact, liquid immersion, an Over Limit alarm event, or custody changes, or anytime the
monitor’s performance is in doubt.

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.

around the perimeter when the instrument experiences the following.

• Gas Event

• Bump Due

• Calibration Due

Non-Compliance Indicator LEDs automatically come on, regardless of user configuration, for the
following.

• Sensor Fail

• Low Battery

• Calibration Fail

• Bump Fail

Non-Compliance Indicator LEDs are designed to alert other people around the user that their unit is
not in compliance. Users are also allowed to change the flash interval and initiate the audible
seconds (10, 30, or 60 seconds). You can turn this indicator on or off for gas events, bump due,
and calibration due. You can also turn “beep” on or off and set the interval (10, 30, or 60 seconds).

The default setting for the Non-Compliance feature is off. The default interval is 30 seconds.

1. Non-compliance events consist of Low, High, TWA, STEL, Negative, and Over Range status.

2. When a gas alarm is dismissed, non-compliance indication continues to indicate a gas event
(flash or flash and beep every 10, 30 or 60 seconds).

3. When a gas alarm is dismissed and if latching alarms is turned on, the instrument continues
to alert (audible, visible, and vibration, once or twice per second). After the button is pressed
to acknowledge the latching alarm, if “Gas Event” in non-compliance settings is on, the
instrument will continue to indicate a gas event.

4. Inserting the instrument in an IntelliDoX clears the non-compliance indication (for gas
events). Anytime the instrument is inserted in an IntelliDoX, the event log should be
recorded in the IntelliDoX. A manual bump test should clear the non-compliance indication
for both gas events and bump test due. Also, a manual calibration should clear both gas
events and calibration due.

IMPORTANT! BUMP TEST THE MONITOR BEFORE EACH DAY’S USE

10. Zeroing

Because usage environments vary, there are many factors that may affect the performance of the
gas detector, including temperature and humidity changes as well as dust. If the ambient air is not
clean, gas readings might be inaccurate. For optimal performance, zero the gas detector once
every 24 hours or after changing of environmental conditions.

1. From the main reading screen, click the button twice in rapid succession to enter the menus.

2. Click the button until you see Zero.

3. Press and hold the button down for [verify this time, it is more than 1 sec] second. The

instrument counts down and then performs a zero calibration.

4. A progress bar indicates that the instrument is being zeroed.

• If the instrument passes zeroing, the message “Passed” appears.

• If the instrument fails zeroing, the message “Failed” appears.

If the instrument passed the zero calibration, it automatically reverts to the main reading screen
after 10 seconds.

11. Bump Testing

Prior to each day’s use, every gas detection monitor should be bump tested to confirm the response of all
sensors and activation of all alarms by exposing the monitor to a concentration of target gas that exceeds
the low alarm set point. A bump test is also recommended if the monitor has been subjected to physical
impact, liquid immersion, an Over Limit alarm event, or custody changes, or anytime the monitor’s
performance is in doubt.

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.

1. From the main reading screen, click the button twice in rapid succession to enter the menus.

2. Click the button until you see Bump.

3. Press and hold the button down for 3 seconds. The instrument counts down and then

performs an AVV (audible, visible, vibration alarm) test, where it turns on three groups of red
LEDs, green LEDs, the buzzer, and vibration alarm, one at a time. The user can choose to
pass or fail after the test.

4. Press and hold the button to acknowledge the results. You should see “Apply Gas?”

5. Press the button to initiate the test.

13. Replacing The Filter & Sensor

The sensor needs to be replaced when it is unable to be calibrated or behaves erratically. Also, the
filter should be inspected periodically, and it should be replaced if it shows signs of accumulated
dust, dirt, or debris.

13.1. Filter Color Reference

One of the holes in the sensor cover has a clear plastic window. While the other holes allow
ambient air (and dirt, debris, etc.) to reach the filter, the window keeps the part of the filter under it
clean. As a result, it is easy to visually confirm that the filter needs replacement by simply
comparing the clean spot with the other spots.
