INTRODUCTION

Congratulations on your purchase of the SAN-10 Personal CO2 Monitor and Data Logger. It is designed to alert employees who work in enclosed areas where carbon dioxide buildup may cause personal harm. If CO2 buildup occurs, it will show the level on screen, flash, alarm and vibrate. In addition the SAN-10 includes built-in data logging and a man-down alarm that uses an accelerometer to set off the alarm if a sudden shock to the unit (like the wearer falling down) occurs.
The SAN-10 uses a non-dispersive infrared CO2 sensor to provide long term stability. It is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.

OPERATION

Power button

1. When the Monitor is turned off, press the power button to turn on the unit.
2. When the Monitor is turned on, press the power button  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 readings displayed. The monitor starts taking measurements when power on and updates readings every 2 seconds.

Menu Status
By pressing the menu button for 5 seconds, the unit enters into “Menu status”.
There are six menu items by pressing the menu button shortly to loop switching between AIR, N2, Hx.x, Lx.x, A ON/AOFF, SC, Px, Log and E (exit).

The menu times are further described in the table below:

to implement Ambient Air Calibration (300~600ppm).
N2 (“ ”)| Nitrogen Calibration. Press the power button  to start nitrogen calibration (0~200ppm).
H0.5/H0.5T/ H1.0/H1.5/H2. 0/H2.5/H3.0/ H3.5/H4.0| High Alarm Threshold setup.
User presses the power  button to switch the high alarm threshold: H0.5 (5000ppm), H0.5T (5000 ppm TWA), H1.0 (1000ppm), H1.5 (15000ppm), H2.0 (20000ppm), H2.5 (25000ppm), H3.0 (30000 ppm), H3.5 (35000 ppm) and H4.0 (4000ppm).
L0.5/L0.5T/L1.0 /L1.5/L3.0| Low Alarm Threshold setup.
Press 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 A OFF| Man down alarm set on/off.
Press the power button  to switch “A ON” to turn on the man down alarm or “AOFF” to turn off the man down alarm)
SC (“ ”)| Real time clock setup
Press the power button  to enter the real time clock setup:

1. Press the  button to switch between Year ( ), Month (), Day (), Hour (), Minute (), Second () and   . to exit.
2. Press the power button  to increase the value until the correct time is set. This value is a cyclic change. Press the power button  again to save and exit the menu status.

For example, set the month to February by pressing the power button  in “ ”:

---|---
Px| Data logging period setup
Press the power button to switch the data logging period between: P30 (30 seconds), P60 (60 seconds), P120 (120 seconds or 2 minutes), P300 (300 seconds or 5 minutes), P600 (600 seconds or 10 minutes) or P900 (900 seconds or 15 minutes).
Log (“ ”)| Data logging memory operation
Press the power button to switch the data logging memory operation between:

• EP (Export data logging by USB)
• RES (Reset the memory)
• E (Exit without operation).

E| Exit. Press the power button       to exit the menu status.

Alarm Threshold
The SAN-10 is equipped with audible, visual and vibration alarms to alert users when the ambient oxygen concentration exceeds either of the two factory preset alarm levels:

• Danger High Alarm: LED will flash and audible alarm will sound 3x / sec.
• Warning Low Alarm: LED will flash and audible alarm will sound 2x / sec.

There are high and low alarm thresholds in the SAN-10. Both high and low alarms have five thresholds: 5000ppm, 5000ppm TWA, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5% and 4.0%. Obviously, the high alarm threshold should not be less than the low threshold. They can be the same alarm level.

Automatic Atmospheric Pressure Compensation
The CO2 measurement is affected by atmospheric pressure or altitude changing.
When users are at high altitude, compensation is made internally to ensure maximum monitor accuracy.

This device has automatic atmospheric pressure compensation for CO2 concentrations by means of a digital atmospheric pressure sensor integrated in the unit.

Man Down Alarm
Falling by breathing dangerous gases can cause serious injury and even fatality to workers. If the Man down alarm function 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 in order to identify a sudden fall or impact and a lack of movement for a period of 6 seconds.
Once alerted, you can turn off the man-down alarm by pressing either of the two buttons.

Reset Button
Users can reset the unit by pushing a reset button through a hole on back of shell.

CALIBRATION

• Step 1. Power the unit on by pressing and holding the power button for 3 seconds

• Step 2. Press and hold the ºF/ºC button for 5-10 seconds to open the first menu

• Step 3. Use the ºF/ºC button to scroll through the first menu which will read:

  • AIR (Ambient Air Calibration Option)
  • N2 (Zero Nitrogen Calibration Option)
  • L 0.5 (Low alarm threshold)
  • H 3.0 (High alarm threshold)
  • A ON (Alarm option. Turns the alarm on and off) f) E (To exit the menu and return to home screen)

• Step 4. Perform AIR or N2 calibration
  “AIR” Ambient air calibration

  • Follow above instructions to access the menu

  • The “AIR” option is the first to appear

  • Bring the unit OUTSIDE or use 400ppm CO2

  • Press the power button to start the calibration

  • If the screen reads “FAIL” repeat until the calibration passes
    *IF THE MONITOR DOES NOT READ IN THE 300-600 PPM RANGE BEFORE PERFORMING THE CALIBRATION, IT WILL NOT CALIBRATE IN THE FIRST MENU.
    “N2” Nitrogen calibration

  • Follow above instructions to access the menu

  • Go to “N2” option

  • Expose the device to nitrogen gas

  • Press the power button to start the calibration

  • If the screen reads “FAIL” repeat until the calibration passes
    *IF THE MONITOR DOES NOT READ IN THE 0-200 PPM RANGE IT WILL NOT CALIBRATE IN THE FIRST MENU.

• Step 5. (USE ONLY IF THE DEVICE IS NOT IN RANGE AND FAILED TO CALIBRATE IN THE FIRST MENU)
  To open the second menu press and hold the ºF/ºC button while already in the first menu.

• Step 6. This menu will allow you to calibrate without range limitations.
  The second menu will read:

  • -AIR (Ambient Air Calibration Option without limits)
  • -N2 (Zero Nitrogen Calibration Option without limits)
  • E (To exit the menu and return to home screen)

• Step 7. When calibration is complete make sure the unit is reading within the span values.
  You can test with fresh air which should read about 400ppm CO2.

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 for factory calibration at a nominal fee.

Cleaning and Storage

• Apply sparingly with a soft cloth and allow drying completely before using.
• Do not use soap or Alcohol cleaning.
• Do not use aromatic hydrocarbons or chlorinated solvents for cleaning.

TROUBLESHOOTING

Button for more than 5 seconds
Check that the Li-ion battery is charged
If monitor is charged but will not turn on, contact support
Monitor is not recognized by computer or software| Verify that software and drivers are installed correctly before attaching monitor to PC.
Verify the software and drivers were installed before the monitor was plugged into the PC with the USB cable.
Verify that the ftd2xx.dll file is in the same folder as the executable program.
Try using a different USB cable.
Windows reports “unknown device” error| Follow these instructions for troubleshooting GasLab driver installation.
Slow response| The log file stored in the monitor is very large. The monitor needs time to transfer data to your computer.
Readings do not change| Confirm the monitor is correctly connected to the computer. Make sure the computer recognizes your monitor and connects with your monitor successfully.
