all white, when the battery needs to be replaced.
A: Battery Replacement: Battery is low and no more measurements are possible. Replace the battery immediately with a CR2032 lithium button cell. 1- Power off the thermometer before replacing the battery • A malfunction may occur if the power is on during battery replacement. If a malfunction occurs, restart the device. 2-Twist the battery cover on the back of thermometer to loosen the cover and remove the old battery. A coin will work well. 3- The new CR2032 battery is installed positive side up. • Take care that the metal contacts at the top of the battery compartment are not bent. 4-Replace the battery cover and tighten with a coin. Q: Display shows dashes: A: Hold the button and device steady for two seconds. A: Check batteries. Q: Error messages: A: Reads Hi- Ambient temperature is above 390.2 degrees Fahrenheit. A: Reads Lo - Ambient temperature is below -27.4 degrees Fahrenheit. A: Reads oFF – Automatic shut off after 15 seconds. Q: Accuracy: A: Item to be measured should be at least twice the size of the beam. A: Will not read thru glass to an object. You will measure the temperature of the glass. A: Dust, steam, smoke, etc. can cause errors. A: Low batteries may cause inaccurate measurements. Q: How do I select Fahrenheit or Celsius? A: This unit only reads in Fahrenheit. Q: Will this cause radiation contamination? A: No-this uses passive Radiation Thermometry -An instrument that focuses and detects the infrared radiation emitted by an object in order to determine its temperature.
A: All objects emit radiation caused by the motion of the atoms of which they are made. This thermal motion of atoms increases with temperature so does the radiation emitted. This is what is measured. A: No radiation is transmitted during the measurement. A: No touch provides accurate measurements at a variety of temperatures. Q: Display is blank (no dashed lines, numbers or letters). A: Hold the button for 2 seconds. This unit will power off after 15 seconds. A: Remove the battery from display. Press any button 20 times. Install a fresh battery. If the display does not show lines or numbers with in 30 seconds, you may need to replace the display. Q: Display has missing segments (all or part of a number or letter are missing). A: This is generally a power related issue. The batteries may be overpowered or underpowered. Remove the battery from display. Press any button 20 times. Leave the battery out of the display for 1-2 hours. Install a fresh battery.
