1 OPERATION MANUAL LASER INFRARED HYGRO-THERMOMETER Mdel:8903/8904/8906 Mdel: 8857

2 Thank yu very much fr purchasing this Laser Infrared Hygr-Thermmeter! This unique meter design with 3 H.V.A.C &R must parameters in 1. The meter designed as battery perated fr Humidity,Air temp., Dew Pint, Wet Bulb, Surface Temp. & Temp. Differential measurement. The sensr is als specially prtected by gear damper device. While the sensr is retracted, the meter will nt wrk. The sensr designed t aut detect the air temp. and humidity if it is nt retracted. The psychrmeter is a micr prcessrbased design. A must device fr HVAC engineers use. N need t whirl the meter r refer t the chart. Easy t get wet bulb, dew pint and surface temp. Quickly! Features : INTRODUCTION Gear damper t prtect sensr. Infrared t measure surface temp. Triple LCD digital display. T1-dew pint functin.(t1=surface temp.) Emissivity adjustable. Handheld size, easy t carry. Lw battery indicatin. Fast respnse. Accurate reading. Dew Pint calculated in secnds. Wet Bulb calculated in secnds. Micrprcessr circuitry fr reliability. Aut pwer ff time frame adjustable. Red laser indicatr included. Back light fr dark places. 1

3 MATERIAL SUPPLIED This package cntains: The meter x 1 Battery x 4 (AAA size ) Operatin manual Calibratin salt bttles (33% and 75%) are ptinal Hard carry case AC t DC adaptr is ptinal RS232 cable is ptinal WARNING Imprtant: Press the gear damper device befre peratin. While the sensr is retracted, the air temp. and humidity will nt be displayed n the LCD. Press the gear damper device again t retract the sensr while turn ff the meter. T retract the sensr will help t maintain the sensr away frm dirt. 2

8 LOW-BATTERY Tw level lw battery indicatin: -Level 1: Battery indicatr will flash when meet level 1. In this situatin, the meter will wrk nrmal hwever users shuld prepare new batteries. -Level 2: Battery indicatr will always display n the LCD while meet lever 2. In this situatin, users need t change batteries immediately. 1. Open the battery cver n the rear side. 2. Remve the expired batteries. 3. Insert new 4pcs AAA batteries and make sure the batteries are inserted with crrect plarity, put n the cver. AC TO DC ADAPTOR The cmpatible AC t DC adaptr is 6~9V, at least 200mA. 6V is the best chice. Please be suggested nly t use 6V adaptr when perating the meter with red laser targeting functin. If using 9V adaptr when the meter red laser targeting functin is active, the red laser mdule might be damaged. 7

9 CALIBRATION 1.Turn ff the meter and plug the meter prbe int the 33% salt bttle. Pressing + at the same time and then press key as well t turn the meter n. The meter will enter calibratin mde will flash n LCD. After 30 minutes, the flashing stps t indicate the 32.8% calibratin prcedure is finished. 3.Mve the meter prbe t the 75% salt bttle and pressing t enter 75.3% calibratin. 4.Als 75.2 will flash n LCD. After 30 minutes the flashing stps t indicate the whle calibratin has been cmpleted, and the calibratin data has been saved in memry. Press key mre than 2 secnd t turn ff meter. Nte: a)yu can exit calibratin withut saving by pressing key mre than 2 sec. befre step 5. b)aut pwer ff is disable in calibratin mde. c)in rder t get high accuracy, yu have better t d the calibratin at 23 degree C. d)t plug the meter prbe int salt bttle, slightly rtate the prbe int bttle and DO NOT push t hard. 8
