四、    Operation

1.    After installing the battery correctly, press  to turn the meter on. It enters the measuring state. The LCD screen displays 00.0. The default unit after turning on is W/㎡.

2.    Press “W/B” to select the unit W/㎡ or Btu, as desired.

3.    Make measurements after unit selection. If the display on the screen is 399.0 or OL, it indicates the measurement will or already has overloaded. At this time, please key in R to switch the range. The range after switching is 1-3999 W/m²（or Btu/（ft²-h））.

4.    If you need to read the maximum value in this measurement process, press “PH” first in the measuring state. The screen displays “PH.” Then conduct measurement. It can measure the peak value at this time and retain it. Press “PH” once again to exit the peak value retention function.

5.    Press “DH” during measurement and the LCD screen displays “H” and the displayed value is locked at the same time. Press “DH” to exit the data retention function to continue measurement.

6.    After the measurement is completed, press  to turn the meter off.  

五、    Battery replacement

1. When the battery voltage becomes too low, the low battery symbol “       “will appear on the screen, indicating that the battery needs to be replaced. If it is not replaced in time, the measurement accuracy will be affected.

2. Open the battery door and take out the battery.

3. Correctly install a new 9V battery.

4. If the meter is not used for a long period of time, please take out the battery to prevent damage to the meter from leakage of the battery.
