OPERATION
Note:
LCD backlight will turn off automatically after 5 seconds of inactivity.
➢ When LCD backlight is off, press either button to turn on the backlight. It will notturn
the monitor off or change the °C/°F setting.
1. Power button
1.1 When the Monitor is turned off, press to turn on the unit.
1.2 When the Monitor is turned on, press for 3 seconds to turn off the unit.
When the unit is first turned on, it performs 5 seconds countdown for Monitor warm up, then
enters normal display with current CO2, temperature, and humidity readings displayed. The
monitor starts taking measurements when power on and updates readings every 2 seconds.
The device can’t shut off alarm, if power off will come back in alarm mode and must delay.
2. Temperature Units Button
2.1 Temperature Unit
Press shortly to switch two temperature units: °F and °C.

2.2 Menu and Configuration Settings
Menu Items
Functional Description
AIR
“AIR” means Ambient Air Calibration. User presses the
power button to implement Ambient Air
Calibration (300~600ppm).
N2
“N2” means Nitrogen Calibration. User presses the power
button to implement Nitrogen
Calibration (0~200ppm).
H0.5/H0.5T/H1.0/
H1.5/H3.0
Current Defaults are L.0.5 H1.0
High Alarm Threshold setup.
User presses the power button to switch the high alarm
threshold: H0.5 (5000 ppm), H0.5A (5000 ppm), H1.0 (10000
ppm), H1.5 (15000
ppm), and H3.0 (30000 ppm).
L0.5/L0.5A/L1.0/L1.5/L3.0
Low Alarm Threshold setup. User presses the power button
to switch the low alarm threshold: L0.5 (5000 ppm), L0.5T (5000
ppm TWA), L1.0 (10000 ppm), L1.5 (15000 ppm),
and L3.0 (30000 ppm).
A ON/ AOFF
Setting Man down alarm function on/off. User presses the
power button to switch “A ON” (allowing Man down
alarm) or “AOFF”
(prohibiting Man down alarm).
E
User presses the temperature
button to exit the menu
status.
By pressing the temperature button for 13 seconds, the unit enters in to Menu status. There
are six menu items by pressing the temperature button shortly to loop switching between
AIR, N2, LX.X, HX.X, A ON/AOFF and E (exit).
The menu items are described in the following table.

3. Calibration
There are two calibration methods: Ambient Air (300-600ppm) and Nitrogen (0-200ppm).
By pressing the temperature unit button for 5 seconds, the monitor will enter CO2 calibration
mode. While in calibration mode, press the temperature button quickly to switch between
AIR (Ambient Air Calibration) or N2 (Nitrogen Calibration). Press the power
button to confirm.
Zero calibration requires 100% nitrogen (0% CO2) calibration gas, a flow regulator and flexible
tubing.
The Atmospheric calibration will not require additional materials but must be performed in
outdoor (300-600ppm fresh air) during the entire procedure.
See Section 2.2 Menu and Configuration Settings, to change settings.
4. Alarm Threshold
There are default thresholds: 5,000 ppm CO2 (low alarm) and 1% CO2 (Short Term Exposure Limit)
(high alarm). The alarm thresholds can be changed dependent on the user, to L0.5 (5000 ppm),
L0.5T (5000 ppm TWA), L1.0 (10000 ppm), L1.5 (15000 ppm), or L3.0 (30000 ppm).
If the measured CO2 value exceeds the define Low Alarm threshold, the alarm LED will flash red
at 2Hz and the audio alarm “de de … de de …” will sound. If the CO2 level exceeds the
High Alarm threshold, the LED will flash faster and the audio alarm will increase. To alert
users in a noisy environment, the monitor will also vibrate.
See Section 2.2 Menu and Configuration Settings, to change settings.
5. Automatic Atmospheric Pressure Compensation
The displayed CO2 level is affected by atmospheric pressure or change in altitude. To insure
maximum accuracy, this monitor has automatic atmospheric pressure compensation for CO2
concentrations by means of a digital atmospheric pressure sensor integrated in the unit. No
calculations or maintenance is required.
See Section 2.2 Menu and Configuration Settings, to change settings.

6. Man down alarm
Falling by breathing dangerous gases can cause serious injury and even fatality to workers. If the
Man down alarm function in ESSAN-10 is set on, ESSAN-10 can detect falls and send a man
down alert which will activate the audible and visual alarms and alert other people in the area.
The man-down detection uses a three-axis accelerometer to automatically monitor the user’s
movements. If a sudden fall/impact is followed by a lack of movement for 6 seconds, the
alarm will sound. Turn off the alarm by pressing either of the two buttons.
See Section 2.2 Menu and Configuration Settings, to change settings.
7. Reset Button
Users can reset the unit by pushing a reset button through a
hole on back of shell.
MAINTENANCE
Calibration
The ESSAN-10 comes pre-calibrated from the factory. However, the CO2 sensor should be
calibrated at least once a year, or as described in your company’s safety procedures. You can
perform the calibration yourself, or you can return it to us for factory calibration at a nominal
fee.
The temperature and humidity sensors do not require calibration and should remain accurate for
the life of your unit.
Cleaning and Storage
The front cover and case can be cleaned with a mild solution of detergent and water.
Apply sparingly with a soft cloth and allow to dry completely before using. Do not use
aromatic hydrocarbons or chlorinated solvents for cleaning.
