5 Operation 5.1 Powering the meter 1. Remove the protective cap from the humidity sensor/thermometer assembly. 2. 3. Press the button to switch on the meter. If the battery indicator shows that the battery voltage is low or if the meter does not power on, replace the battery. See section 6.2 Battery replacement, page 21. 4. Press the button to switch off the meter. 5.1.1 Auto power off The meter enters sleep mode after 30 minutes of inactivity.
5 Operation 5.2.1 Internal moisture sensor 1. 2. 3. Press the button to enter the Moisture mode. The and indicators are displayed. The indicator is also displayed, indicating that the meter is displaying relative measurements. The ambient temperature is displayed on the secondary display. Place the internal moisture sensor (located on the rear side of the meter) on the surface of the material to be tested. The relative moisture reading is displayed on the main display.
5 Operation 4. The indicator shows the currently selected material group number. Refer to section 7 Material groups, page 22. To change the material group number, do the following: 1. Press and hold the and terial group selection mode. The 5. buttons for 2 seconds to enter the Ma- indicator flashes. 2. Use the numbers. 3.

5 Operation 3. Press the button repeatedly to cycle through the display of relative humidity, dew point temperature, and mixing ratio. • Relative humidity: The displayed in percent (%). • Dew point temperature: The indicator is displayed and the reading is displayed in ℃ or ℉, depending on the unit setting. Mixing ratio: The reading is displayed in grains per pound (GPP) or grams per kilogram (g/kg), depending on the unit setting. • indicator is displayed and the reading is 5.
5 Operation • • Steam, dust, smoke, etc., may obscure measurements. To find a hot spot, aim the meter outside the area of interest, then scan across (in an up and down motion) until the hot spot is located. WARNING Do not look directly into the laser beam. The laser beam can cause eye irritation. WARNING Do not use the laser pointer near explosive gases or in other possible explosive areas. Injury to persons can occur. 1. Press and hold the 2. diode. The indicator is displayed.
5 Operation 3. The dew point temperature is displayed on the main display. The IR temperature of the surface is displayed on the secondary display. The bar graph indicates the level of risk for condensation: • • • 4. If the IR temperature is more than 14℃ (25℉) above the dew point temperature, the bar graph is empty. If the IR temperature is 3–14℃ (5–25℉) above the dew point temperature, the bar graph indicates a percentage of full scale.
5 Operation 5.7 Selecting measurement units There are two sets of units; US and metric. The unit setting can be changed at any time in any mode, by pressing and holding the button for 2 seconds. The unit setting applies to all modes. It is not possible to, for example, display moisture in g/kg while showing temperature in ℉. US unit setting: • • • Temperature is displayed in degrees Fahrenheit (℉). Mixing ratio is displayed in grains per pound (GPP). Vapor pressure is displayed in millibars (mBar).
5 Operation 5.8.3 View data 1. Press and hold the button for 2 seconds to enter View data mode. The indicator flashes, and the data stored in that location is displayed. 2. Press the 3.
