Pressing the MODE button will switch between the battery
meter and hydrogen meter.
The first line of the LCD is used to display the battery or
hydrogen meter. The second line of the LCD displays the
percent hydrogen concentration or peak hydrogen value.
The hydrogen meter is a logarithmic bar graph covering
0.001 to 100 percent hydrogen. Open boxes on the bar
indicate peak value and filled boxes indicate current value
.
The LED’s indicate changes in hydrogen concentration:
•
Green
indicates that hydrogen is less than 0.001%
(10ppm).
•
Yellow
indicates that hydrogen has been detected.
•
Red
indicates that the hydrogen concentration is increasing
over the previously sensed value.
The audible alarm sounds whenever a new peak is found.
Note: Due to the extreme sensitivity of the sensor, after a
hydrogen exposure the sensor my take 60 seconds or
more to return to a zero (less than 0.001%) reading
.
Error Mode
- The LCD displays “Error” and the LED is
continuously red, indicating a non-operating state.
•
Turn off
the system and verify that the Sensor Module,
and Wand Assembly if used, are properly connected and
firmly seated.
•
Check that the system is receiving sufficient power.
Ensure that the Battery is properly installed into the
Controller.
•
Allow Batteries that have been in an extreme temperature
to warm or cool to within 10 to 45 degrees C.
•
If the instrument continues to fail to operate, call

Reset Mode -
To improve recovery time, a user activated
reset function has been incorporated. *Refer to section 7 for
a more complete description of the use of this function.
•
Remove
the handheld detector away from the leak and
into a hydrogen free environment. Wait for the unit to
display <0.1%.
•
Depress
between the up and down arrows for
approximately two seconds. A query will appear on the
LCD display confirming the reset.
•
Push the
enter
button to confirm and the unit will go
through a 15 second reset during which the LED will
illuminate amber. Once the reset is complete the LED will
illuminate green.
•
NOTE: The reset function will
not
activate until less than
0.1% hydrogen is displayed on the LCD display.
