SHORT INSTRUCTION MANUAL
General description
The is an accurate hand-held datalogger that displays & records relative
humidity, temperature, CO2 and calculated parameters such as dew point and wet bulb.
These short instructions are limited to a description of the main functions and installa-
tion of the device. The detailed instruction manual can be found on the internet at
www.senseair.se
Programming
Most of the settings, such as memory clear, CO2 alarm, units( C/ F), sampling rate,
pressure compensation and real time clock can be changed using the function keys.

Power Supply
The uses four AA re-chargable batteries as power source. To insert
(replace)the batteries, use the screwdriver enclosed to loose two screws and put in
the batteries in correct polarity with good contact.
Connection to PC or Laptop
Connect the via mini USB cable to a PC or Laptop. Recorded data can be
easily downloaded with the software enclosed.
Please charge the batteries for eight hours on first time use. To charge the
batteries, power off the meter and plug in the 9VDC adaptor enclosed. Wait until
"End" appears on LCD to indicate the charging process is completed
(approximately eight hours).
TAKING MEASUREMENT
The meter starts measurement when power on and update readings every second.

press the key. Under normal mode, each press of
displays the MIN, the MAX, the AVG and the current
value in sequence (Fig.9~11). To return to normal mode,
press to escape(Fig.12)
In the MIN/MAX/AVG mode, it shows the corresponding
readings on main display and the accumulated time of
this mode. The maximum time interval for this function
is 18h.
Press to switch the displayed parameters (Fig.13).
Distinguish the normal display and current review by
checking the time display format. In normal display, date

ALARM
The meter features audible alarm to give warnings when CO2 concentration exceeds
the limit. (See “Meter Setup” section for setting alarm threshold). It emits beeps
(about 80dB) when CO2 level goes over the set value and stops only when the
readings fall below the set value. It beeps again when value goes over the limit.

The sensor has an automatic calibration function to secure long-term accuracy. If a
calibration is desired, press simultaneously for 3 seconds to turn on the
meter and enter calibration mode. Press or key to select 400ppm CO2
calibration (Outside Air calibration). Press to start and see“CAL” and CO2 value
blinking on LCD. Wait about 10 minutes until the blinking stops and the calibration is
completed and back to normal mode. While choose 0ppm CO2 calibration, remove
the cap from meter rear side and plug the CO2 CALIBRATOR pipe into the sensor
hole beneath. Wait about 10 min until the blinking stops and the calibration is
completed and back to normal mode.

Humidity Calibration
This meter can be calibrated either via 35% & 80% salt bottle or humidity generator.
o
The ambient condition is recommended as stable 25 C. While the meter is powered
off, plug the sensor probe into 35% salt. Press , , simultaneously for three
seconds to turn on the meter and enter calibration mode. Press or to select
35.0% calibration and press to start. “CAL” and calibrating value are blinking on
the LCD.
CAUTION:
Do not calibrate the humidity without the default calibration salt. Otherwise,
it will cause permanent damage. Contact SenseAir for calibration salt or
services.
Single point calibration will cause error code E11 or non-accurate reading.
Always do dual point calibration to complete a process. Suggest to calibrate
low humidity first.
CO2 Calibration
CAUTION:
Do not calibrate the meter in the air with unknown CO concentration.
2
Otherwise, it leads to inaccurate measurements.
Ensure the batteries are with fully charged during the calibration to prevent
frominterruption or failed calibration. When the accuracy becomes a concern
after long time usage, return to dealers for standard calibration.

DATA LOGGING
The meter can automatically record HUMIDITY/TEMP/CO2 for long term environment
monitor. The memory capacity is 6000 points for each parameter. Users can set up
sampling rate from one second to 4hours, 59 minutes and 59 seconds. The factory
preset rate is 30 second.
