When the infrared thermometer shows er1, what should I do?
1. The infrared thermometer's output inaccuracy is significant. If the online infrared thermometer is replaced, it's possible that the new infrared thermometer chosen has a linear range that differs from the old one, leading to sensitivity. When adjusting the infrared thermometer, error typically needs to be recalibrated. Of course, the infrared thermometer's output inaccuracy is considerable, and it's also possible that the device was not calibrated when it was shipped from the manufacturer.
2. The infrared thermometer's output signal is unstable, which is caused by the temperature source itself. The temperature of several temperature sources is typically not constant. Check to see if the infrared thermometer's output signal is stable. If only the instrument display is unsteady, the display instrument's anti-interference capability is weak.
