INTRODUCTION
Thank you for purchasing desktop HCHO meter.
It is used to measure HCHO concentration,air temperature
and relative humidity with visible and audible alarms.
This HCHO meter is an ideal instrument for indoor air quality
(IAQ) diagnosis and HVAC system performance verification.
MATERIALSUPPLIED
(1) Meter
(2) UniversalAdaptor
(3) Operation manual
(4) 4 pcs batteries.
(5) USB cable
(6) White Box
POWER SUPPLY
The meter is powered by Super heavy duty batteriesAAA x 4 pcs
(Recommended) or an AC adaptor(9V/0.5Aoutput)

KEYPAD (CONTROLS)
1) MODE : HCHO mode,MAX,TWA,STEL
2) SEL./R : Edit alarm function
Logger mode: Long press to key start/off.
3) TRH.M. : Temp. Humidity mode. Setting/ Next
4) UNIT : Select Temp. unit
5) POWER: Turn meter on/off, alarm on/off.
OPERATION
Warning: Remove batteries when not in use to prevent battery
leakage (Out of warranty) and power consumption.
(a) POWER ON/OFF
Put battery or plug in adaptor, meter turns on automatically .
LCD shows current HCHO, RH & Temperature, Date and Time.
Three(3) smiley icons indicate the indoor air quality level and
appear on the top of first layer display.
Note:
(1) When low battery, meter will restart and logger will stop if
user switch to adaptor.
(2) Please use properly power source, input voltage:
100~240 VAC,50-60Hz
Output voltage: DC 7.5~9.0V
Output current: 0.5A,or the meter will be damaged.
(3) Battery life approx. 120 hours when continuous used
(b) TAKING MEASUREMENT
The meter starts the measurements when powered
on and response time is less than 30 sec.
Do not hold the meter close to any other source of HCHO.
Note:
(c) HCHO MODE
MODEIn the HCHO Mode, pressbutton to switch HCHO
display. The top layer of display will cycle from HCHO,
Maximum, TWA, STEL.

Note 1:
1) MAXIMUM:
The unit automatically records maximum reading
and minimum reading after powered on.(MINIMUM is
always 0.00ppm for HCHO meter)
2) TWA: ( Time Weighted Average 8 hours)
The meter keeps updating the reading every minute. If
the meter has been powered on for less than 8 hours,
the TWA value will be the weighted average of readings
since powered on.
3)STEL: (Short-Term Exposure Limit in 15 minutes weighted
average)The meter keeps updating readings every
minute. If the meter has been powered on for less than
15 minutes, the STELvalue shows the weighted average
of reading taken since powered on.
4)RESETMAX:

MAINTENANCE
Cleaning and storage:
1).The meter should be cleaned with a damp cloth and mild
detergent when necessary.
2). Store the meter in an area with moderate temperature
and humidity.
MANUALCALIBRATION TO ZERO
Before start HCHO manual calibration make sure the area is
ventilation and no HCHO environment. Ensure the calibration
completed, to use adaptor during calibration is recommended.
HCHO meter is completed calibration in factory before
packed. Manual calibration is only for meter inaccuracy.
When power on, long pressbutton moreUNIT
than 6 seconds, the value will turn into“00000"
and flashseconds.60
After calibration completed, display will show
full LCD icon for a second. Meter will restart
automatically to return normal measurement.
BATTERY INDICATION
When battery is low (HCHO consumes power ),the reading
of HCHO will be terribly high, could be couple thousand in
ppm.“LO BAT” is flashing at the bottom of the screen,
near calendar and time. Replace new battery when LO BAT
shows.
SETTING DATE & TIME
a) Real time and date:
The meter shows Mo./Date and Hr/Min on the 3rd layer of
