Operation
Power-Up
1. Press the Power Button.
2. A 2 second delay will occur before the display
becomes visible.
3. 10 seconds will elapse before current CO
2
readings
are displayed.
4.
“Warm-up”
will display for approximately one minute.
During this one minute warm-up, adjustments can not
be made to the sensor.
Elevation Correction
- The sensor is shipped with the
elevation setting set at “zero” or sea level. The sensor, like any
other gas measuring device is directly affected by altitude
changes. If you are at an altitude greater than 500 feet, an
adjustment should be made to assure maximum sensor
accuracy. The altitude correction is very small for changes of
500-1000 ft. (e.g. 10-15 ppm/500 ft. increment). Once the
elevation correction is set it will be stored in the monitor
memory and will be retained if the unit is turned off or batteries
removed.
To change the default setting using Elevation Correction
follow the steps below.
1. While in Normal Mode press the “Mode” button once.
The Elevation LCD will begin blinking.
2. Press Enter.
3. Press mode to toggle the elevation reading between
feet (ft) and meters (m)
4. Use the Up/Down button to adjust the alti-tude. The
altitude can be adjusted in increments of 500 (feet) or
100 (meters). Once the correct altitude is set, press
Enter to lock the setting and return to normal mode.
Temperature or Cfm/person -
The lower digital display will
cycle through the display of the following units when up/down
buttons are pressed: Temp°F, Temp°C, cfm/person(fm), turn
lower display off.
Stand-alone Monitoring -
Once the batteries have been
installed and the Elevation correction has been made (as
described in the steps above), the sensor will begin to
Start-Up
Battery Operation
- For portable use, the monitor operates
on 4 AA batteries.
Expected battery life is as follows:
Normal
(Non-Alkaline)....
Up to 50 hours
Rechargeable
..................
Up to 60 Hours
Industrial Alkaline
..........
Up to 70 Hours
Display
Listed below are the modes of operation visible on the display.
Warm-Up
When the power button is pressed, the monitor enters a one
minute warm-up indicated by the word WARM-UP in the upper
left corner.
On Line
Indicates when a PC is communicating to the sensor via the
RJ45 port in the rear of the monitor.
Normal Operating Mode
After warm-up the sensor will stabilize and display current
conditions.
Adjustment modes
Pressing the mode button can access adjustment modes. The
following information is displayed for each mode. Once the
mode is displayed, press enter to adjust the setting. Press enter
again to leave the adjustment mode.
Flashing ELEVATION
- This feature allows the user to correct
the monitor for elevation changes. ”ELEVATION” will flash in the
lower right corner of the display. Press the enter button and the
current elevation above sea level will be displayed. To change
adjust from ft. to meters press the mode button. Use the up/dwn
buttons to adjust elevation in 500 ft. (100 meter) increments.
When finished with adjustment press enter and the adjustment
will be saved.
Flashing CALIBRATION
- When the word ”CALIBRATION”
flashes in the middle of the screen the user can enter the CO
2
calibration mode using the procedure described below.
Flashing ”TEMPERATURE”
- When the word ”TEMPERA-
TURE” is flashing at the bottom of the screen the user can enter
the Temperature calbration mode using the procedure
described below.
Flashing CO
2
and ppm
When ”CO
2
” and ”ppm” are flashing on the screen the user can
enter mode to adjust the outdoor reference concentration for
the cfm/person calculation.
See the procedure below for more information.
Calibration in Progress Mode
Displays when calibration is in progress.
Outdoor Concentration Mode
To properly calculate the ventilation rate in the space the CO
2
sensor must know what the outside CO
2
concentrations are.
This mode allows the CO
2
sensor to store in it´s memory the
outside concentration.
It is activated by holding the ”enter button” for 5 seconds when
the monitor is exposed to stabilized outside conditions.
When this feature is activated, CO
2
, PPM and the lower display
should flash.
The instructions below also describe how the outside concent-
ration can be manually set.
Low Battery
- Displays when the power source is low.
Battery Installation -
Remove the battery cover by pressing
the pressure clip (located on the bottom) and pull upward.
Follow the battery diagram imprinted on plastic forproper
installation.
Replace battery cover when battery installation is complete.
Low Battery
- A warning signal.
(Low battery)
, will flash when there is less than 30 minutes of
battery life.
At this point the batteries should be replaced or the AC
adapter should be used as a substitute.
If operation continues, the unit will become inoperable and
only the
Low Battery
will be blink on the LCD display.
AC Power -
The sensor is shipped with a 6 Vdc 500 mA AC/
DC adapter.
To use the AC adapter, connect the plug into the back of the
unit and plug the transformer into any standard wall outlet.
NOTE
Use the supplied adapter.
Using the wrong adapter may cause damage to the unit.
If power is lost during operation, battery operation will not
function as a back up.
