※In the calibration, must away from the
environment or equipment with
electromagnetic waves.
0 ppm Calibration
The meter is running 0 ppm calibration as
default.
Put the meter in an area free of CO and enter
the calibration mode. It calibrates
automatically. The duration of calibration time
is 5 minutes.
100 ppm/500 ppm Calibration
After end of the 0 ppm calibration, the screen
will display 100 ppm, then press
button to select 100 ppm or 500 ppm value
and press button to start calibration. It
will show a blinking 100 ppm or 500 ppm on
the upper display and the lower-left corner of
the screen will display the value of theADC
and place the meter into the sealed box filled
with standard gas(e.g. 100 ppm/500 ppm) for
5 minutes, then the calibration will be done
automatically.

TM-801/TM-802

※ Check if the reading meets calibration value. If
it does, the calibration is not, repeat the
procedure.
17.PRECAUTIONS
Keep the meter away from electromagnetic
interference (EMI) which may cause erratic
readings.
Recovering time is required when meter
exposed to high level CO. The longer the
exposure, the longer recovering time is
needed.
