User's Guide Pinless Moisture/Humidity Meter with Memory + IR Thermometer Model MO295 mBAR GPP 01 MEM STORE MO295 RH%
Introduction Congratulations on your purchase of the Extech MO295 Pinless Moisture Meter with Built-in IR Thermometer and 20 Point Memory. Monitor moisture in wood and other building materials with no surface damage with the Pinless Moisture sensor (Pin-type Moisture Probe included). Measure Humidity and Air Temperature with built-in probe plus non-contact InfraRed Temperature with IR design. Advanced functions provide Grains per Pound, Dew Point and Vapor Pressure calculations.
Safety Use extreme caution when the laser pointer beam is on Do not point the beam toward anyone's eye or allow the beam to strike the eye from a reflective surface Do not use the laser near explosive gases or in other potentially explosive areas Features Quickly indicates the moisture content of materials with Pinless technology without damaging the surface; Optional remote Pin-type probe (MO290-P) allows for moisture readings at different penetration levels (3ft/0.
Operation Powering the meter 1. Remove the RH sensor protective cap before use. 2. Press the power 3. If the button to turn the meter on. symbol appears or the meter does not turn on, replace the battery. Humidity (Dew point, GPP, g/kg) Measurements 1. Press the power 2. Press the RH button button to turn the meter on. 3. Relative Humidity will be displayed in the primary display and the temperature will be displayed in the secondary display. 4.
Infrared Temperature Measurements 1. Press the power button to turn the meter on. 2. Press the IRT button to enable the IR thermometer and the laser pointer. The laser pointer icon will flash while the mode is active. 3. Aim the laser pointer at the surface to be measured and read the surface temperature in the secondary display. 4. Release the IRT button.
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. 2. 3. 4. 5. Press the power button to turn the meter on. Simultaneously press the MOIST and RH buttons. The “COND” icon will appear. Point the meter at a surface, press the IRT button to measure the surface temperature.
Moisture Alarm Set Procedure: 1. 2. 3. 4. 5. 6. 7. 8. With MOIST displayed, simultaneously press the MOIST and MODE buttons. The “HIGH” icon will appear on the display. Press the ▲or ▼button to set the high limit desired. Press the STORE/ALARM SET button to save the value and proceed to the LOW set value. With the “LOW” icon in the display, Press the ▲or ▼button to set the low limit desired. Press the STORE/ALARM SET button to save the value and to return to the normal mode.
