Page 3: Safety Information
INTRODUCTION This instrument is a portable, compact-sized Humidity Temperature Trans- ducer designed for simple one hand operation. Uses Platinum Resistance Temperature Detector Pt385/1000W (Alpha=0.00385) as temperature sensor, and uses thin film polymer capacitive type relative humidity sensor as hygrom- eter sensor. SAFETY INFORMATION It is recommended that you read the safety and operation instructions before using the humidity temperature transducer. -
Page 4: Specifications
SPECIFICATIONS GENERAL Low battery indication: The "Red LED" is displayed when the battery voltage drops below the operating level. Accuracy: Stated accuracy at 73.4°F ± 9°F, <75% relative humidity. Temperature Coefficient: 0.056 times the applicable accuracy specification per °F from 32°F to 64.4°F and 82.4°F to 122°F. Operating environment: 32°F to 122°F at <75% relative humidity. - Page 5 ELECTRICAL TEMPERATURE Temperature Scale: Fahrenheit. Temperature Sensor: RTD Pt385/1000W . Measurement Range: -4°F to 140°F. Temperature Output: 10mV/°F. Accuracy: ±0.9°F 32°F to 122°F ±1.8°F -4°F to 32°F, 122°F to 140°F RELATIVE HUMIDITY Humidity Sensor: Electronic capacitance polymer film sensor. (The sensor is unaffected by water condensate, is immune to most reagent vapors) Measurement Range: 0% to 100%RH.
- Page 6 Sensor Hysteresis (excursion of 10% to 90% to 10% RH): ±1%RH typical. Sensor Temperature Dependence: Negligible between 32°F to 122°F. OPERATON 1. Plug the humidity temperature transducer test leads into the Vdc input jack and common or ground input jack on the DMM. Observe polarity. 2.

Page 7: Special Considerations
SPECIAL CONSIDERATIONS • Before a reliable measurement can be made, the measuring hygrometer and medium to be measured must be in temperature and humidity eguilibrium. • Temperature measurement errors Due to too short measurement time, sunshine during the measurement, heating, cold outer walls, air draft (e.g. fans), radiating hand and / or body heat etc. -
Page 8: Operator Maintenance
OPERATOR MAINTENANCE Battery Replacement Power is supplied by four 1.5V (AAA size) batteries. The "LOW BATT" red LED lighted when replacement is needed. To replace the batteries, remove the screw from the back of the meter and lift off the battery cover. Remove the batteries from battery contacts. - Page 9 OMEGA's Customer 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. However, this WARRANTY is VOID if the unit shows evidence of having been tampered with or shows evidence of being damaged as a result of excessive corrosion;...
