1.0 Introduction
The RECON is a portable-single gas detector for detection of combustible or toxic gases. It is intended for detection of
combustible or toxic gas in commercial or industrial facilities to keep workers safe, and/or detect a potentially explosive gas
environment.
The RECON, adopting excellent-quality sensor, makes detection in the way of natural diffusion. It has good sensitivity and
reproducibility. The detector adopts embedded MCU controller, easy to operate.
The RECON incorporates a special high strength, anti-slip rubber case providing anti slip handleability.
The RECON has an ingress protection rating of 65.

5.0 Maintenance of the RE ON
To maintain proper battery function and life the Recon should be operated once a week for 6 to 8 hours and then placed on
charge see Section 5.3
The RECON maintenacne section allows access to Zero, Calibration, Calibration target gas and alarm point adjustment menus.
To enter the maintenance menus section you must start with the instrument OFF.
WARNING:As all the parameters of this mode may endanger the safety of the operator, so please perform the operation carefully
5.1 Calibration of the RECON
With the instrument OFF, press POWER amd SET buttons and
hold for 5 seconds, the RECON begins a self-test. If the self-test passes,
then after a short time, it indicates request for password.
Enter the password, factory set to 1270, by using the UP button to
increment the digit and
the SET button to accept the indicated digit and move the cursor.
Only when the correct password is entered can the detector enter the maintenance menu.
If there is no operation or the password is wrong, the detector will be deactivated. So, please input the correct password in time.
5.1.2 Zero calibration
WARNING:This operation should be carried out in the clean air. Otherwise the accuracy of the detector will be affected. When
entering into the next mode, if the displays shows E, the air is not clean, or the sensor is destroyed. choose another calibration
location or replace the sensor.
NOTE:Not used with Recon Oxygen units
At this time, if SET button is pressed or no operation within 1 minute, the
RECON will accept the present concentration as the zero point, and then enters
into the mode of calibration point set up.
Connect the calibration cover to the instrument, attach the regulator to the gas
cylinder.
To Exit press POWER button, menu will bypass the calibration step to enter into the mode of alarming level set up, press
POWER button advance and exit.

5.1.3 Calibration Point Adjustment
In this mode, display is the last concentration of gas used to calibrate the
instrument. Press UP or Down button to modify the display.
NOTE:Not used with Recon Oxygen units
NOTE:20.9% Oxygen is the only calibration level to be used with Recon Oxygen units
Press the SET button to accept the level or within 1 minute, the RECON
will accept the present concentration as the calibration gas concentration.
The display will change to 0..
Open the valve on the regulator
Within 30 seconds, if the RECON detects the calibration gas, it will start up the
calibration date analysis procedure by itself. Continue gas flow.
In 2 to 3 minutes the
RECON
will automatically adjust the conversion
arithmetics to complete the gas response process. Then the RECON saves the
best arithmetics to complete calibration.
W ARNING : The RECON must self calibrate, please avoid touching any
buttons, otherwise the accuracy will be effected badly.
After that it enters into the L-alarm set up. Press POWER button twice to
advance and exit.
If the RECON can not reach half the calibration figure within 30 seconds, or the gas concentration is outside the maximum
drift range of the sensor, the E icon will light and 0000 will be displayed. This means the gas is not proper for calibration or the
sensor is depleted.
Verify calibration gas is correct. If correct retry calibration sequence. If failure occurs sensor may need to be replaced.
Remove calibration cover from instrument.
To exit calibration menu.
Press SET button 3 times and then the POWER button 4 times.
Press the SET button then

5.2 Alarm Levels Adjustment of the RECON
5.2.1 Set up of L-alarm (Low Alarm)
With the RECON Off press and hold the POWER and SET buttons until unit activates.
When 0000 is displayed, enter the password, factory set to 1270, by using the UP button to increment the digit and the SET
button to accept the indicated digit and move the cursor. When the correct password is entered, the display will advance.
Press the POWER button to advance to alarm set menu.
In this mode, the L-alarm level can be adjusted. Press UP or Down button to adjust the flickering figure according to
your need, and then press SET button to complete the set up. After that, it enters the H-alarm set up.
NOTE:The display will not allow an unacceptable alarm level.
5.2.2 Set up of H-alarm (High Alarm)
01In this mode, the H-alarm level can be adjusted. Press UP or Down button to adjust the flickering figure according
to your need, and then press SET to complete the set up. After that the detector will automatically turn off.
NOTE:The display will not allow an unacceptable alarm level.
5.3 Battery Charging
When the battery voltage is low, the RECON will not function properly. To recharge the batteries of the RECON: The
RECON must be Off, connect the AC connector plugs of the charger to a 110VAC or 220VAC outlet and plug the charging
cable into the RECON. The detector will activate automatically and indicates that it is being charged. When the charging
cycle is completed, the display will indicate full charge.
W ARNING : D O N OT start the battery charge process with the RECON power on; otherwise the charge speed will be
adversely affected. Always charge the battery in normal ambient air. Do not charge the RECON in a hazardous
area to be monitored, to avoid fire or explosion. Disconnect the charger after 24 hours, failure to do so will
damage the battery. Typical expected battery life and time to recharge:
RECON for CO, H2S, O2 30+ Hours, non-alarm condition: Recharge time: approximately 4 – 6 hours
RECON for %LEL CH4 8 hours, non-alarm condition: Recharge time: approximately 6 hours
NOTE:To maintain proper battery function and life the Recon should be operated once a week for 6 to 8 hours and then placed
on charge.
5.4 Sensor Replacement
Sensor life in the RECON is typically: 2 years for Carbon Monoxide & Hydrogen Sulfide and 1year for Oxygen and
Combustible.
The sensor needs to be replaced when the RECON can no longer be calibrated or if the sensor becomes erratic.
Contact ENMET for sensor replacement information.
