What should I do if the infrared thermometer displays er1?
1. The output error of the infrared thermometer is large: if the online infrared thermometer in the online infrared thermometer is replaced, it may be that the linear range of the new infrared thermometer selected is inconsistent with the original one, resulting in sensitivity Error, usually need to be re-calibrated after changing the infrared thermometer. Of course, the output error of the online infrared thermometer is large, and it may also be that the infrared thermometer was not calibrated when it left the factory.
2. The output signal of the infrared thermometer is unstable: this reason is the reason of the temperature source itself. Many temperature sources themselves generally do not have a constant temperature. Monitor whether the output signal of the infrared thermometer is stable. If only the instrument display is unstable, it means that the anti-interference ability of the display instrument is not strong.
