Thank you for purchasing OMEGA’s RH650 9-in-1 Thermo-Hygrometer/Moisture Meter. Please read this user’s manual carefully and thoroughly before using the instrument. The RH650 is a handheld instrument that will prove useful to four groups of users: water damage restoration contractors, HVAC/R system installers and technicians, facility maintenance professionals and electronics manufacturers. - Page 5 Behind the back cover of the RH650 are two metal plates. When the meter is powered on, the plates are given small and opposite charges. The potential difference causes current to flow, creating a three-dimensional electric field.

Page 9: Setup Instructions
APO will not appear on the LCD. SELECTING A PARAMETER The RH650 can measure and display the value of eight different moisture-related parameters. When the meter is in measurement mode, you select a parameter by pressing either the UP> and <DN... -
Page 10: General Controls
GENERAL CONTROLS Changing measurement units. By default, the RH650 uses Imperial units for all parametric readouts. To switch to metric units, press the UNIT button. Ambient temperatures and dew points will then be displayed as °C rather than °F; absolute humidity values will be stated in g/m rather than in mg/L;... -
Page 11: Recalling Stored Readings
SETTING ALARMS The RH650 allows you to set alarms that will repeatedly sound the beeper if the measured RH level or the moisture level of a material (measured by either the pinless or pin-type sensor) is above or below a certain value. - Page 12 LOW setpoint. It also causes LOW to disappear and returns the RH650 to operation in real-time RH measurement mode. To disarm any of the six alarms (HIGH and LOW for RH, MOIST INT and MOIST EXT), you must reset its setpoint to 100.0% or 0.0% by pressing the UP>...

Page 13: Measuring Moisture Levels
In both moisture level measurement modes, the RH650’s display adds a vertical bar graph to the digital readout of a material’s moisture level. The bar graphs (see below) have no scale; they exist only to provide an analog way to quickly track changes in relative moisture levels. -
Page 14: Checking Calibration
CHECKING CALIBRATION Although you cannot calibrate the RH650 yourself, you can check the meter’s calibration periodically to assure yourself of the accuracy of humidity-related readings (RH, absolute humidity, dew point and mixing ratio). Factory calibration should minimize the humidity sensor’s drift for several years—well beyond the warranty period. -

Page 16: Operating & Maintenance Tips
LCD, it’s time to install a fresh “9V” battery using the procedure on p.7. • Do not immerse the RH650 in water or get water on it. • Do not disassemble the unit. Opening the case voids the warranty. - Page 17 Service Department will issue an Authorized Return (AR) number immediately upon phone or written request. Upon examination by OMEGA, if the unit is found to be defective, it will be repaired or replaced at no charge. OMEGA’s WARRANTY does not apply to defects resulting from any action of the purchaser, including but not limited to mishandling, improper interfacing, operation outside of design limits, improper repair, or unauthorized modification.
