Eastern Energy JL269 LED User manual

Note:
zIt’s forbidden to charge it in the dangerous area. Otherwise, it
will demage the detector or cause fire & explosion.
zDuring charging, it’s normal that the area around the battery will
be heated.
zAfter the detector turns off automatically, please charge the
battery within 12 hours, so as to avoid that the battery cannot
work due to too low voltage.

and store it in dry environment.
zIf replacing the battery, make sure they are with the same
capacity. If using alkaline batteries, please don’t charge them.
Sensorusingandreplacement
In normal working status, the sensor life is 2 years. When thesensor
is overdue or defective, please contact the seller for correct
replacement instruction.

Safety Information
Before using the device, please first carefully read and follow the
following information to operate the device:
zPlease don't use the defective detector. Before using, please
check if there is crack or spare part missing. If yes, please
contact the seller.
zIt's suggested that the user carry out the "Impact Test" before
using everyday to check if the detector works normally or not.
zOnly spare parts which are specified for JL269 or permitted by
the seller are allowed to be used.
zOnly the charger which is specified for JL269 is allowed to be
used to charge the device. It's forbidden to charge the device in
the dangerous environment.
zPlease don't expose the device with detection unit of "ppm" and
"LEL" to the exceeding-range gas for long time. Otherwise, it
will badly influence the performance and even damage the
device.
zIf exposed to the environment consisting of leaded compound,
sulfocompound, organic phosphorus compound or silicon, the
gas sensor will be poisoned. Please don't use the device in the
above environment.
zPlease don't expose the device to the environment which
consists of H2S, hydrocarbons gas or high corrosive gas for
long time. Otherwise, it will restrain the response of the gas
sensor and reduce the sensitivity. If the device has to be used in
the above environment, please carry out the Impact Test before
using it.
zPlease don't expose the device to the environment which has
electric shock, strong magnetic field or serious continuous
mechanic shocking.
Calibration procedure:
8.1 Hold both and buttons to turn on the detector and the
detector enters into calibration warm-up period. LED lights flash in
turns, showing the warm-up period is about 3 minutes.
8.2 After warm-up, only 1pc of green LED light is on, the detector
enters into zero calibration status. If the detector is in clean air,
press buttn to save the zero information. Then, “Power”light is
in green color and 3 green LED lights flash. Zero calibration is done.
After zero calibration, 1 yellow LED is on and 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. “ Power”light is in yellow color, 3 green LED and 3 yellow
LED are on and then flashing. The calibration of second point is
done.
8.3 After all calibration, “ Power” light is in green color first and
then turns off. The detector turns off.
Note:
There are 2 calibration points. Please first calibrate zero point and
then the second point.
During calibration, if the sensor is abnormal, “ Fault” light and
“OL” light will indicate. Please note it.
Charging
Please charge the battery when the detector is turned off. The color
of “ Power”light of the charger will show the voltage 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 charge from the power source.

4. Battery voltage checking
In detecting status, by pressing both and buttons, the
user can check how much voltage left in the battery. LED lights flash.
The voltage left is equal to the quantity of the LED lights. If press
both and buttons, the detector will return to the detecting
status.
Moreover, the user can also check the voltage by checking the color
of “ Power” light.
Color Voltage
Green Enough
Yellow Not enough
Red Low. Please charge in time.
5. Open / close audible alarm
In detecting status, the initial setting of audible alarm is open. The
more gas leaks, the higher the audible alarm frequency. If too noisy
on spot, the user can use the earphone purchased by himself.
Press button can open or close the audible alarm function.
6. Set present level as zero
In order to exactly find the gas leakage point, during detecting, the
user can set the present level as zero by pressing button.
7. Turn off the detector
Press both and buttons, the detector will be turned off.
8. Calibration
In order to assure the accuracy, it’s suggested re-calibration once
every 6 months.
zThere is a NI-MH battery inside the device. Please don't place
the useless battery together with the rubbish. The useless
battery should be discarded by qualified withdrawers.
zIt's forbidden to disassembly, adjust or repair the device without
permission.
zPlease avoid the device falling from high place or serious
shocking.
zAny other operation beyond this manual, please contact the
seller.

Structure and Functions
Operationinstruction
1. Turn on the detector
Press and hold “ ” for more than 2 seconds and the detector
enters into self test status. All LED lights turn on in turns and then off.
At the same time, the buzzer and sensor carry out self test. After self
test, if the sensor can make zero calibration within 5 seconds, the
detector enters into detecting status. If sensor fault or 5-second zero
calibration doesn’t finish, please wait for longer time. Please check
“OL” light. If it is off, then zero calibration finishes and the
detector enters into detecting status.
2. Impact Test
It is suggested to make Impact Test before using every day, so as to
make sure the detector work normally.
Test method:
After turning on the detector, put it into the gas with known level or
standard gas. If the display, alarming signal and buttons work
normally, then it can be carried out for detecting. If no response to
the gas or “ Fault” light is on, please contact the seller for solving
the problem.
3. Detecting
Put the sensor into the gas environment. The quantity of LED lights
and sound frequency will show the gas concentration of the
environment. With concentration increases, first the green LED
lights and the buzzer frequency increases. When the concentration
exceeds the green LED range, yellow LED lights, and then red LED
lights. At the same time, the sound frequency interval will turn higher.
If the concentration reaches the highest of the detection range, the
“OL” LED will light.
