To Next PageTo Next PageWhy does the temperature fluctuate on my Fluke Thermalert 4.0?
If the temperature readings on your Fluke Accessories fluctuate, it might be due to incorrect signal processing settings. Try correcting the Peak/Valley Hold or Average settings. Also, ensure the instrument has a proper ground connection by checking the wiring and grounding.
What to do if my Fluke Thermalert 4.0 show erroneous temperature?
If you are getting an erroneous temperature reading from your Fluke Accessories, several factors could be the cause. First, verify the sensor cable continuity. Second, check for any obstructions in the field of view and remove them. Third, ensure the window lens is clean. Finally, make sure the emissivity setting is correct.
