The XT is available with two types of display; Standard and Real Time. This section will illustrate
the difference between the two display types.
On XT’s equipped with the Standard Display, the remaining lifetime clock indicates how much
longer the detector will operate. This is shown on the display as a countdown of remaining months
(indicated by the icon), then days ( ) and finally hours ( ). The example in the table on the next
page shows 24 months remaining.

Should the Standard Display XT unit be exposed to a level of gas in excess of the alarm set points
the unit will display the concentration of the gas. If the measured reading exceeds the range of
the detector then the numerical digits will flash.
The Real Time Display XT displays the concentration reading all the time. The lifetime remaining
is displayed in the self-test mode.

5. Maximum Gas Reading
The XT records the maximum readings measured under an alarm condition, and records the
number of hours since this occurred. As each new higher level of gas is detected this counter is
reset to zero, and after 24 hours has elapsed the counter is also reset to zero hours.
The maximum gas readings (minimum for oxygen) can be viewed by pressing the Test button within
24 hours of the gas alar m. This will cause the instrument to perform a self-test (see Section 6),
after which the alarm set points and the maximum readings will be displayed. For instance;

6. Performing a Self-Test
When the Test button is pressed the unit checks the sensor, circuit, batteries, audible and visual
alarms and vibrating alarm.
After 24 hours has elapsed since the self-test was last performed the Test Pass icon ( ) will
be blinking. The self-test must then be performed by pressing the Test button. The detector will
do the following:
Turn on all the display elements
•
Tests the audible and visual alarms and vibrating alarm
•
Check the battery, electronic circuit and sensor
•
Perform a sensor test
•
Display the level 1 and level 2 alarm setpoints
•
Display the maximum (minimum for O2) gas reading (if such a reading has occurred)
•
If a gas alarm has occurred since the Test button was last pressed the relevant alarm
•
level icon will be displayed
Lifetime Remaining (for units with Real Time Display)
•
The result of the self-test as follows:
•
Self-Test Result Display Audible Alarm Visual Alarm
Pass None None
Fail 1 long beep 1 flash
If the self-test fails repeat the self-test. The XT will warm up for one minute before the next selftest is performed. If it fails three consecutive times then the detector will display an error code
(see Section 10).
XT Series Personal Gas Detector
11
Additionally, the XT will periodically check its batter y, electronic circuit and sensor. If it fails the
Test Fail icon ( ) will be shown and the Test Pass icon ( ) will blink. If it passes then the Test
Pass icon will be displayed.
7. Testing Sensors and Alarms (Bump Testing)
To ma intain optimal accuracy, the detecto r should be periodicall y supplied with a known
concentration test gas (bump test) and if the readings are outside of 15% of the applied gas
concentration, a span calibration should be performed, under conditions of standard temperature
(15°C to 25°C/59˚F to 77˚F) humidity and pressure. Follow local regulations and/or your company’s
policy on the frequency of bump testing. For more information on test gas, contact your local
Honeywell Analytics representative.
8. End of Life Alarm
When the XT has less than 1 day of remaining life it will flash the digits, as below:
End of Life Warning End of Life Reached
When the XT’s life has ended the display will blink as shown above, the audible will beep once
every 15 seconds, and the visual will flash once every 15 seconds, and the vibrating alar m will
operate once every 15 seconds, until the Test button is pressed. The audible will then be turned
off, and the detector will shutdown, displaying the relevant error code (see Section 10).
12
XT Series Personal Gas Detector
9. Safety Shutdown
In the event that the battery runs out before the end of life is reached (due to excessive alarms)
the battery icon will blink, the audible alarm will beep once every 15 seconds, and the visual alarm
will flash once every 15 seconds, until the Test button is pressed. The audible alarm will then be
turned off, and the detector will shutdown. A shutdown condition can also occur due to failure of
the electronic circuitry or sensor. The relevant error code is shown (Section 10).
Note:
Shut down conditions due to extreme temperatures can be reset by moving the
detector to a normal range temperature and pressing the Test button.

11. Zero Calibration (Oxygen Span)
This must be performed in a clean atmosphere, and it is recommended that it be performed daily
or after any gas alarm. Depress the Test button for 5 seconds. The instrument will initiate a zero
by showing a countdown with a ‘0’ for zero calibration, followed by a countdown from ‘20’ to ‘0’.
When the zero calibration has been completed the XT will indicate a pass by beeping twice,
flashing twice, and the ( ) symbol will flash for 5 seconds.
blink
If the zero calibration is not OK then the XT will give a single beep and a single flash, the Test
Fail icon ( ) will be displayed, and the zero calibration should be repeated.

XT Series Personal Gas Detector
12. Optional Span Calibration (CO AND H
While the XT requires no calibration for its lifetime of 24 months there may be an occasion when
it is deemed necessary to carry out a calibration, for instance, if a self-test fails. To carry out the
span calibration the user requires the following additional equipment which can be purchased
from Honeywell Analytics.
Gas cylinder containing a known concentration calibration gas as follows:
•
S Versions Only)
2
Toxic Gas Calibration Concentration
H2S 25 ppm in air
CO 100 ppm in air
A gas regulator supplying the gas at 300ml/min flow rate
•
Tubing for use between the regulator and the test adaptor (supplied)
•
Carry out the zero calibration procedure as described in Section 11. Only if the zero calibration
is successful can a span calibration be performed. At the end of the zero calibration procedure,
the test button must be pressed continuously for 5 seconds while the ( ) symbol is still flashing.
Connect the gas cylinder and test adaptor and apply the gas at 300 ml/min. The instrument will
display a ‘C’ (for calibration), and count down from ‘60’ to ’0’.
If the span calibration is successful the unit will give 2 beeps, 2 flashes and displays the Test Pass
icon ( ). If it fails the instrument gives a long beep, long flash and displays the Fail icon ( ) (the
calibration remains as it was before the span calibration was attempted).

16. Accuracy Statement
To achieve optima l accuracy, the detector should be p erio dically supplie d with a k nown
concentration test gas, and if the readings are outside of 15% of the applied gas concentration,
a span calibration should be performed, under conditions of standard temperature (15°C to
25°C), humidity and pressure.
Poisons should not affect the accuracy of the XT but certain compounds can block the gas access
port of the sensor, such as silicone oils, giving a lower than expected reading.
