Installation Instruction
1. Location Selection
The location selection of the gas detection transmitter is essential to achieve the best detection
results. In the selection of location, we need to consider the following factors: the density of gas in a
leaking point, proportion of target gas, the impact of surrounding buildings, condition of production
equipment, wind direction and annual meteorological conditions and even the location of windows
and doors in an indoor environment.
We provide the following suggestions for your reference:
A. Maintain a proper distance between the detector and the possible gas leaking point. It would
react too fast or too frequent if the distance is not enough, which may paralyze people's mind.
B. The detector must be located in the downwind of the possible leaking point.
C. If installed indoor, but the source of the leak is outdoor, the detector must be installed at the air
inlet.
D. Determine the height according to proportion of target gas in air.
E. Determine the quantity of detectors according to the condition of possible leaking point,
frequency of sta
ff a
ttendance and time of stay as well as the economic e
ff
ect.
F. Consider to increase quantity of inspection point if the equipment is old.
G. Protect the detector from radiation of high temperature heart source. Environments of both
very high temperature and very low temperature will a
ff
ect the result and lifespan of the detector.

Method of Calibration
To guarantee the measurement accuracy of the transmitter, regular calibration and maintaining
rigorous record is necessary.
Devices needed for calibration: a bottle of sample gas used for range calibration (60%F.S standard
gas in normal site),relief valve, flow meter of 0~1000ml/min, transparent and smooth conduit for
gas, standard gas housing, digital multimeter, stopwatch and etc.
Note: The value of transmitter WB (4mA) , WC (20mA) , Wz (zero potentiometer), WA (range
potentiometer, also known as calibration potentiometer) and host alarm has been set right before it
leaves the factory. User should not adjust casually. It is the value of zero potentiometer (Z) and
calibration potentiometer (S) needed to be set on spot.
1. Zero Point Calibration
Open the detector in clean air, if there is readings after counting down.
Press the button "MENU" of the remote controller, the detector displays "F-01", press"+" or"-",
change the function to "F-04", and click "OK". The detector value will be displayed as 0.
In the zero calibration of oxygen detection transmitter, we must use nitrogen of purity over
99.99%.

2. Steps of Installation
Connect wire to correspondent terminals. Don't work with power on. The arrangement of
terminals di
ff
ers according to the type of transmitter. The definition of di
ff
erent wires:
Red: positive-input of power (12 to 24V)/24V+
Black: ground wire of power/24V
Yellow:4-20mA output.
Orange: RS485A
Blue: RS485B
Brown: Free
Fix the detector on the wall with expansion bolt, make sure the transmitter is downward, or the
detector cannot work property. Users can also separate the bracket and transmitter according to the
condition on spot, fix the bracket before connection.
For the sake of safety and interference reduction, please connect the housing with reliable ground
wire. For the wire between the transmitter and the main engine, the shorter, the better. And protect
the wire with iron pipe.

2. Range Calibration
1. Enter into "F-07"as the same way above . The
"F-07" value is the concentration of the standard
gas, initialized to half of the measure range. This
value can be modified through the"+" and"-" keys to
make it consistent with the standard gas
concentration which need to be calibrated. Press
"OK" to exit.
2. Enter into"F-08"to change 0 into 1,then back to
detection interface.
3. Connect the 200-400mL/min standard gas in
detection interface, when the detector value is
stable, press "OK" for 3 seconds, then the
instrument will be calibrated automatically. The
measured concentration value is consistent with the
value set in "F-07".
4. After calibration, left the detector in the air for a
while. Shut o
ff t
he power when the detector value is
close to zero.
