Calibrate the
sensitivity of the
hydrogen detector.
1. When the
default screen is
displayed on
the transducer
LCD, hold
down FUNC
for more than
5s using a
magnetic bar,
and release the
button.
2. After the
Parameter
setting menu is
displayed, the
LCD turns
purple, and
displays P0000.
Enter 1111 and
tap FUNC. The
LCD displays
SEN1.0.
3. Tap <. The unit
digit or tens
digit blinks.
Adjust the
sensitivity by
pressing ▲ or
▼ using the
magnetic bar.
Then press
FUNC.
Calibrate the
sensor by
choosing SEN
(sensitivity
adjustment) and
ADD
(correction
value
adjustment) in
the Advanced
Parameter
menu.
Formula:
Calibrated value
= Original
density x
Sensitivity +
Correction Value
After a hydrogen
detector is
installed and
powered on, its
sensitivity
attenuates by
1-2% per month.
After half a year,
the total
sensitivity
attenuation will
reach 10%.
If there is no
standard gas
onsite, change
SEN1.0 to
SEN1.1 after
half a year to
increase the
sensitivity by
10%, and change
it to SEN1.2
after the detector
has been running
for a whole year.
In this way, the
sensitivity of the
hydrogen
detector is
linearly
corrected and
compensated.
Replace expired or faulty
hydrogen detectors by following
instructions in documents
delivered with the hydrogen
detectors.
The service life of a sensor is less
than five years.
