3.0 Operation RECON/4
C
AUTION
: RECON/4 is set to auto zero calibrate after turning on. Turn on the RECON/4 in clean air. Incorrect readings will
occur if the RECON/4 is turned on in contaminated air.
3.1 Activate RECON/4
Press and hold the button for 1second and then release it. After the buzzer gives a short sound once, the RECON/4 is on.
The RECON/4 will display ENMET information and run a self test.
The display will indicate “Starting Warming up” with each test listed below
Example: Alarm, Vibrator, “High alarm”, “Low alarm”, “STEL” and “TWA”.
After that, it enters detecting status. At this time, it displays the concentration of O2, H2S, CO and Combustible gas in the
environment.
3.1.1 Display Conservation
Following the warm up, to conserve battery life, the display will fade to black in about 30 seconds. An audio confidence
“chirp” will activate every 3 minutes to indicate the RECON/4 is active.
N
OTE
: Pressing the button or any gas detected event will recall the display.
3.2 Deactivate RECON/4
To turn the RECON/4 off, press and hold the button for 3 seconds, the buzzer gives a short sound twice and long sound once.
The RECON/4 is now off.
3.3 RECON/4 Alarm
(1) When the gas concentration reaches the preset alarm levels, the RECON/4 will activate relative alarms:
The LED lights flash, audio alarm sounds and vibratory alarm activates.
The user can cancel audio and vibratory alarm by pressing and releasing the button: The first press will cancel audio alarm, and
the second to cancel vibration.
(2) When the RECON/4 is kept in an environment with the target toxic gas, if the gas concentration is more than the maximum
average level of TWA or STEL, the RECON/4 will give TWA or STEL alert. At this time, the user can also cancel the audio
and vibratory alarming by pressing the button as described in above Section (1).
Alarms sound when its sensor faults or at low battery status. Please refer to the LCD display for details.
3.4 RECON/4 Status Check
When the RECON/4 is on and in non-alarm status, press and release the button, the LCD screen will display max. gas level and
min. level*, STEL**, TWA**, current time, serial number(SN) and version number(VER) in turn.
N
OTE
: *Only O2 sensor has such indication.
**Only toxic gas sensors have STEL and TWA alert.
3.5 RECON/4 Battery Charging
When the battery voltage is low, the RECON/4 will not function properly. To recharge the batteries of the RECON/4: The
RECON/4 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/4. 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
:
DO NOT start the battery
adversely affected. Always charge the battery in normal ambient air. Do not charge the RECON/4 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.

4.0 Calibration
C
AUTION
: The RECON/4 will Auto Zero when you enter the calibration menu. Please fully charge the RECON/4 and put the
instrument into a clean air environment before proceeding with this procedure.
The RECON/4 is capable of calibrating all active channels at the same time. However, you may elect to calibrate individual
gas sensors. During calibration, the RECON/4 automatically determines if a single gas or multi gas is being applied.
With the RECON/4 ON, Press and hold the button, the RECON/4 will turn OFF; continue to press the button until the
instrument restarts. The Display will show Calibration followed by Warming Up, and will list the proper concentrations of
calibration gasses.
After warming up, the RECON/4 begins Zero calibration (Zero Cal). A bar graph will appear indicating the zero calibration
time (1 minute). Connect the gas cylinder to the regulator and the calibration cover. DO NOT open the valve on the
regulator.
When Zero Cal is complete the screen will display Span Cal and a bar graph and the active sensors with their associated
reference numbers.
Note: The RECON/4 is comparing internal data to the sensor reference numbers listed in the display. The bar graph will fill
from left to right. Note sensor reference numbers. If they are stable (not changing), proceed to the next step. If they are
changing wait for the bar graph to fill (4 minutes). At completion of the 4 minutes the calibration process will automatically
continue and the display will now indicate Cal Span Time 2 Min and a % sign.
At completion of the 4 minute Span Cal, or when you see that the reference numbers for the sensors are stable, connect the
calibration cover to the RECON/4
Open the valve on the regulator to apply the calibration gas. The bar graph will fill in and the % sigh will change to indicate
the calibration completion time. Do not press the button on the RECON/4 or interrupt the gas flow during this procedure.
The RECON/4 will automatically analyze the gas and process the calibration.
After calibration, the screen will display the calibrated gas(es) name and relative data. For each calibrated sensor you will see
two sets of calibration numbers, Zero and Span for each sensor that detected calibration gas, and then the RECON/4 will
automatically turn off. If you do not see both sets of numbers for the sensor(s), calibration was not completed successfully.
Note: The RECON/4 automatically determines if a single or multi gas is applied, you will only see calibration numbers for
the gas/gases that are being applied; the remaining sensors are not affected.
If you are calibrating individual sensors repeat the above process
If the calibration was unsuccessful wait one hour and repeat the calibration procedure
