Specifications - Installation and Operating Instructions

TE-TH2-10

The Model TH2-10 Thermo-Hygrometer Pen is a compact handheld device that

measures temperature, humidity, dew point, wet bulb, and heat index. For

ncreased accuracy, calibration salt baths can be used to field calibrate the

umidity sensor before taking measurements. Minimum, maximum, and average

eadings can be displayed on the large 4 digit LCD display. High and Low alarms

r provide audible and visual indication of changes to the ambient humidity.

FEATURES

1) Temperature and relative humidity measurement. ) Calculate dew point temperature and wet bulb temperature.

) Calculate heat index and wet bulb global temperature.

) Hi Temperature alarm setting (Heat Index/WBGT).

5) Data hold & Maximum/Minimum/Average function.

6) Auto power off function.

7) Self-calibration by salt bottle (Optional) at 33% & 75% humidity points.

8) Quick response and high accuracy.

OPERATING INSTRUCTIONS

Please read the manual completely before using this device.

KEY FUNCTION

(1) PWR: Turn on / off the meter. (2) HOLD: Data hold mode. (3) MODE: Select measurement modes: Temp. (temperature), RH (Relative Humidity), HI (heat index), DP (dew point), WB (wet bulb), HI WB (wet bulb global temperature / WGBT).

OPERATION Power On/Off

Press the POWER button to turn on the meter. The meter will display TEMP reading and icon with a beep sound. To turn off the meter, press the POWER button for more than 2 seconds.

Maximum and Minimum Mode

With the meter already on, press the POWER button less than 2 seconds. The MAX icon with the highest reading appears on the LCD. Press the POWER button

umbers will cycle from 0 to 9. It will jump

n to the next digit to the right when the desired number (0 to 9) is reached. So for this example, we need a “1” in the thousand unit column. When the number

esired is reached, it will jump to the next

igit to the right.

Step 2:

Keep pressing the MODE button, the

ame action as before until the hundreds

igit shows ”2". Then release the MODE

d button.

When WGBT alarm is on, HI WB (WBGT) icon with the default value 28.0°C (82.4°F) appears on the LCD. Keep pressing MODE button to increase digit sequencely from hundred digit and release the button when the digit you desired appears. (Please refer to Example 1). Press POWER button to save WBGT setting and the meter will go to normal measurement.

Note: HEAT INDEX: The Heat Index is determined using the dry bulb temperature and

relative humidity. It is based upon charts available from the U.S. National Weather Service. The Heat Index represents how an average person feels relative to climate conditions. For a given temperature, the higher the humidity, the higher the heat index will be.

TROUBLE SHOOTING

Error messages:

Humidity sensor is failed.

E-2

Temperature sensor is failed.

E-3

Operation temperature is too high.

E-4

Operation temperature is too low.

E-5

Some hardware has failed.
