Condensation Mode
The Condensation feature alerts the user when the surface temperature as measured by the IR
thermometer is close to or has reached the Dew Point temperature.
1. Press the power
button to turn the meter on.
2. Simultaneously press the MOIST and RH buttons. The “COND” icon will appear.
3. Point the meter at a surface, press the IRT button to measure the surface temperature. The
small display will indicate the IR surface temperature and the large display will indicate the
difference between the IR temperature and the Dew Point temperature.
4. The meter will then report the potential for condensation on that surface in the following
manner
If the temperature of the IRT is more than 14°C (25°F) above the Dew Point, the
temperature difference shall be displayed, with no other warning.
If the temperature of the IRT is 3-14°C (5-25°F) above the Dew Point, the temperature
difference shall be displayed, along with a standard Condensation Indicator icon. The meter
shall beep once to confirm that the reading is in the risk area.
If the temperature of the IRT is less than 3°C (5°F) above the Dew Point, the temperature
difference shall be displayed, along with a flashing Condensation Indicator icon. The meter
shall beep twice to confirm that the reading is in the high-risk area.
5.
Press the RH button to exit the mode.
Vapor Pressure Mode
Ambient Vapor Pressure
1. With the Condensation mode active, press the MODE button to display the Vapor Pressure in
mBAR (°F) or kPa (°C). Press the
▲
or
▼
button to toggle between mBAR or kPa.
2. Press the MODE button to exit the Vapor Pressure mode.
Surface Vapor Pressure
1.
Enter the Vapor Pressure mode as described above.
2.
Press the IRT button and aim the laser pointer at the surface to be measured to display the
Surface Vapor Pressure in mBAR (°F) or kPa (°C).
Alarm High and Low Limit Setting
High and Low alarm points can be set for Humidity and Moisture measurements.
Humidity Alarm Set Procedure:
1. With RH% displayed, simultaneously press the RH and MODE buttons.
2. The “HIGH” icon will appear on the display.
3. Press
the
▲
or
▼
button to set the high limit desired.
4. Press the STORE/ALARM SET button to save the value and proceed to the LOW set value.
5. With the “LOW” icon in the display, Press the
▲
or
▼
button to set the low limit desired.
6. Press the STORE/ALARM SET button to save the value and to return to the normal mode.
7. If the humidity measurement is lower than the low alarm setting or higher than the high alarm
setting, the meter will beep once every second.
