➢

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

By pressing the temperature button for 11 seconds, the unit enters into Menu status. There

are six menu items by pressing the temperature button shortly to

AIR, N2, LX.X, HX.X, A ON/AOFF and E (exit).

To change the Low and High Alarm Thresholds, switch to L0.5 or H1.0

and press the button shortly to alter between defaults, press to

loop switching between

select, E to exit. The menu items are described in the following table:

Menu Items

Functional Description

AIR

“AIR” means Ambient Air Calibration. User presses the

power button to implement Ambient Air

Calibration (300~600ppm).

“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 thepower 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 (15000ppm),

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).

User presses the power

button to exit the menu.

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 toconfirm.

Zero calibration requires 100% nitrogen (0% CO2) calibration gas, a flow regulator and flexible

tubing. These can easily be obtained online:

https://www.co2meter.com/collections/accessories/products/demand-flow-regulator

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. T o 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. T o 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 func tion in SAN-10 is set on, SAN-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 SAN-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 CO2Meter 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

Attention: Do NOT use soap, alcohol, aromatic hydrocarbons, or chlorinated solvents for SAN-10

cleaning purposes.

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 prior to using.

122°F or < 32°F).

Bump Test Procedure

Bump Test Procedure: Use Carbon Dioxide (CO2) gas concentration greater than 3% (30,000 ppm).

CO2Meter suggests using 4% CO2.

Caution: Perform this test in a well-ventilated area or outside. Inhalation of high concentrations of

carbon dioxide can present serious health risks.

Step 1) Pump CO2 into the Sensor Entry on the front of the device in short bursts. It is also possible

to blow into the device to trigger the alarms; exhaled air is about 3.8% CO2.

Step 2) Make sure alarms trigger at appropriate alarm levels (alarmlevels can be adjusted)

a) Alarm 1 (Low) – 0.5% (5,000 ppm) – LED will flash, and audible alarm will sound

b) Alarm 2 (High) – 3.0% (30,000 ppm) – LED will flash, and audible alarm will sound
