1、 80T-IR/E Extended Range Infrared Temperature Probe Instruction Sheet Introduction The Fluke 80T-IR/E Extended Range Infrared Temperature Probe (the probe) is a noncontact temperature measurement accessory for use with a test instrument capable of measuring DC volts in the millivolt range such as a

2、digital multimeter (DMM). The probe has a temperature range of 32F to 1000F, with a basic accuracy of 3% of reading, and an output of 1 mV dc per F. Temperature is measured by pointing the probe at the surface to be measured, and reading the temperature on the test instrument display. Box Contents T

RadioFans.CN 收音机爱 好者资料库 Safety Information The 80T-IR/E complies with IEC Publication 1010-1- 1990 including Amendment 1, CSA C22.2 No. 231, ANSI/ISA-S82.01 and .03 Safety Standards. W WARNING IF TARGET EMMISSIVITY IS LESS

4、THAN 0.95, THE PROBE CAN INDICATE A TEMPERATURE LOWER THAN THE ACTUAL TARGET TEMPERATURE. AVOID TOUCHING THE TARGET; THERMAL BURNS COULD RESULT. CAUTION Do not place the probe on or around hot objects (70C / 158F). It will damage the probe case. If the probe is exposed to significant changes in ambi

5、ent temperature (hot to cold or cold to hot), allow 20 minutes for temperature stabilization, before taking measurements. Do not operate the probe near large electrical or magnetic fields such as arc welders and induction heaters. These fields can cause measurement errors. Condensation may form on t

6、he lens when going from a cold to hot environment - wait 10 minutes for condensation to dissipate before taking measurements. Connectors must only be plugged into voltage measurement input jacks of the test instruments. Do not touch or hold by the front cone. Temperature readings can be affected by

8、a plugs. Operation To take a measurement, perform the following steps: 1. Plug the red connector into the VW dc input jack and the black connector into the common or ground input jack on the test instrument. 2. Select mV dc on the test instrument. 3. Slide the probe switch forward to the ON position

9、. 4. Point the tip of the probe as close as possible to the object being measured without touching the object. 5. Read the test instrument display. Additional considerations are: After 10 minutes of use the probe will automatically shift to Sleep mode (the display will show 0F). It can be restarted

10、by sliding the switch to OFF and then to ON (see Table 1). Sleep mode extends battery life. However, for maximum battery life, switch the probe to the OFF position. If the test instrument displays an overload condition, switch the DMM range from mV dc to V dc. Increasing the range to V dc moves the

Emissivity All objects emit invisible infrared energy. This ability, called emissivity, is based upon the material that

13、 the object is made of and its surface finish. Emissivity values typically range from 0.10 for a very reflective object to 0.98 for a near perfect black body. The probe senses this energy assuming that the target has an emissivity value of 0.95. This value is factory set in the probe. If the actual

14、target emissivity is less than 0.95, the indicated temperature could be less than the actual target surface temperature. To correct for this, apply masking tape or a coat of matte paint to the target. The resulting target will have an emissivity of approximately 0.95. Table 1. Display CodesCondition

Restart the probe by sliding switch to OFF and then to ON, or replace battery. * All values are nominal. * Although a display code may be present, the displayed reading is valid if the probe is within the specified ambient operating range. Distance to Spot Size Ra

17、tio Distance to Spot Size Ratio (or Field of View) refers to the diameter of the spot that the probe is sensing at a given distance. The closer you are to the object (or target), the smaller the area (or spot) the probe is sensing. For example when the probe is held at a 200 mm (8 in.) distance from

18、 the target, the spot size is approximately 50 mm (2 in.); at 100 mm (4 in.) the spot size is approximately 25 mm (1 in.), and with the probe held at a 50 mm (2 in.) distance from the target, the spot size is approximately 13 mm (1/2 in.). Hot spots can be missed if too large an area is included in

19、the field of view, so get as close as possible!

Measurement Considerations If the surface to be m

20、easured is small (13 mm (1/2 in.) or less), hold the probe as close as possible to the surface (no more than 50 mm (2 in.) away). If the surface to be measured is covered by frost or other material, clean it to expose the surface. If the surface to be measured is highly reflective such as polished m

21、etal, apply masking tape or a matte finish paint to the surface. If the probe seems to be giving incorrect readings check the front of the probe. There may be condensation or debris obstructing the sensor; clean per instructions in the maintenance section. Quick Check For a quick check of the probe,

22、 point it directly at ice immersed in water (slush), the meter should read, within specifications limits, 32F (see Accuracy specifications).
