INTRODUCTION

ADA ZHT 100 (6 in 1) Thermo-Hygrometer equipped with advanced sensor technology is used to measure environmental parameters of storage and production warehouses. It measures ambient temperature and humidity, wet bulb and dew point temperature with MAX/MIN data hold and temperature unit switch capability. The unit adopts smart low power consumption design, with backlit LCD display and data hold.

OPERATION INSTRUCTIONS

1. Unscrew and open the battery lid, place a 9V block battery and put back the battery lid.

2. Rotate the probe protection cap as the direction of arrow indicates while measuring, and make sure the sensor is fully exposed. Press the power button to turn on the unit. To secure a stable reading, place the unit in the target environment for at least 1 minute. The relative humidity is displayed on the upper part of the LCD, while the temperature is at lower part. The backlight turns off itself in 10s, press any button to bring it back.

3. Switch between Celsius and Fahrenheit by pressing the C/F button. “°C” and “°F” will be shown accordingly.

4. Plug the external probe into unit’s JC port (refer to the product overview), to measure object’s surface and internal temperature.

5. If the external probe is not plugged in, press DEW button, and the temperature will be displayed on LCD screen switching between T1 and Dew point only.If the external probe is plugged in, press DEW button,and the LCD screen will display the difference switch-

ing between T1,Dew point DP,Ambient temperature and ΔT=T1—T2.

6. If the external probe is not plugged in, press WBT button and it only shows WBT reading.If the external probe is plugged in,press WBT button, and the LCD screen will display the value switching between Condensation temperature difference and web bulb temperature.If removed, WBT value will be immediately displayed only.

7. Press MAX/MIN button to get the maximum and minimum readings of temperature and humidity,the corresponding value will be displayed on the screen. Press continuously until the “MIN” and “MAX” symbol is not displayed to exit MAX/MIN mode.

8. Press HOLD to hold current temperature and humidity readings. Press again the release.

9. “Low battery” icon will be shown on the LCD when battery is low.

10. Press and hold the power button for 3s to power off the unit. When auto power off function is active, the unit will power off itself in 20 minutes. Place back the protection cap when the unit is off.

11. Auto power off mode can be deactivated.Press the HOLD button first then press the ON/OFF to power on, with the full-displayed information, the auto power off function will be deactivated.

Operation notes

1. Please don’t operate this product unless the manual has been read.

2. To assure accuracy, remove the protection cap and make sure the sensor is fully exposed before taking any measurement.

3. Remove the battery before long term storage. Keep the sensor part away from water or any kind of liquid.

4. To assure accuracy after calibration, do not expose the sensor in saturated environment for long.

5. To avoid damages to the instrument, do not operate near following places a) Vapor and dusty places b) EMF places (Electro-magnetic fields: such as arc welders, induction heaters) c) Static environment d) Heat shock (caused by great and sudden temperature change), wait for 30 minutes until the unit is stabilized before any operation.

6. After long working hours, the sensor may be polluted and the electronic parameters happen to drift. If the measured value is out of the actual measuring range, these steps as follows should be taken to calibrate.

7. Please purchase the standard 33% and 75% humidity salt bottle in the market. A) Please press to deactivate auto power off function and turn the unit on (press the upper left button, then press the middle power button. When the screen be full-displayed, release the upper left button until the normal humidity and temperature values show on the screen). B) Remove the sensor protection cap and press the upper left button and right button. simultaneously . “---” will appear under the screen and “1” will appear on the right side of it. Put the sensor part in the 33% humidity salt bottle for at least 40 minutes. After 40 minutes, the unit adjusts the value to 33% automatically. C) Take out the unit and press the upper left and right button simultaneously. “---”appears under the screen and “2” appears on the right side of it. Put the unit in the 75% standard humidity box for more than 40 minutes. After 40 minutes, the unit adjusts the value to 75% automatically. The calibration work is finished only after the calibration of two continual values. The unit must go through two (“1”-->“2”) regular calibrations. In this way, the calibrations are effective. Moreover, the oder of the calibration values can’t be opposite. Firstly, calibrate in 33% salt bottle, then in the 75% salt bottle. If calibrations are done in 33% salt

battle only, power off the unit manually and then power on the unit, the screen will display “Er2” for 3 seconds. After two calibrations are finished, the unit will work normally when power on.

Battery Safety Instructions
