INTRODUCTION

Thank you for purchasing desktop HCHO meter.
It is used t o 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.

MATERIAL SUPPLIED

(1) Meter
(2) Universal Adaptor
(3) Operation manual
(4) 4 pcs batteries.
(5) USB cable
(6) White Box

POWER SUPPLY

The meter is powered by Super heavy duty batteries AAA 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 o n 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 3 0 sec.

Do not hold the meter close to any other source o f HCHO.

Note:

(c) HCHO MODE

MODEIn the HCHO Mode, press button to switch HCHO

displa

y. 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 STEL value shows the weighted average
of reading taken since powered on.

4)RESET MAX:

Press button to get MAX reading andMODE

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.

MANUAL CALIBRATION 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 press button moreUNIT
than 6 seconds, the value will turn into “00000"
and flash seconds.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 b e couple thousand in
ppm. “LO BAT” i s flashing at the bottom of the screen,
near calendar and time. Replace new battery when LO BAT
shows.
