calibration is done.
After zero calibration, one yellow LED will be lighted on which
means the detector enters into the calibration status of the second point.
Put the detector into the standard gas (level equals to the second point)
and keep it steady for about 30 seconds. Then press
to save the
second point information. “
Power” light will be lighted on in yellow
color, 3 green LED and 3 yellow LED are lighted on and then flashing,
which means the calibration of second point is done. If there are more
than two calibration points, the operating method is same with the second
point calibration. After all points’ calibration finish, “
Power” light
will be lighted in green color and then turns off. The detector will turns
off then.
Note:
There are more than two calibration points. Please carry out
calibration in order, first zero point calibration and then the second point,
the third point.
During calibration, if the sensor responses abnormally, the
“
Fault” light and “
OL” light will be lighted on. Please note it.
6. Charging
Please charge the battery after the detector is turned off. The color of
“
Power” light on the charger will show the voltage level of the battery.
The charging will last for 4 to 7 hours. When “
Power” light doesn’t
flash and it is in green color, the charging is done. Please disconnect the
charger from the power source.
Charging Attention
It’s forbidden to charge the detector in dangerous area. Otherwise, it
will damage the detector or cause fire & explosion.
During charging, it’s normal that the area around the battery will be
heated.
