First, when testing radar level gauges, we must not forget to conduct the measurements while the device is powered on; otherwise, our measurements will be meaningless. When performing live measurements, the main thing to check is whether the current output of the radar level gauge is normal. Secondly, when performing signal detection on the radar level gauge, we need to bring different probes into contact with the gauge’s measurement pins at the same time to check whether a short circuit will occur. Third, when checking the filtering capacitor of a radar level gauge, we need to short-circuit the positive and negative terminals of the electrolytic capacitor first; however, it must not be discharged, as this could lead to errors in measurements as well as damage to the internal wires. Fourth, if a radar level gauge is used in a humid environment, it is very likely to cause malfunctions in the gauge. We need to check each circuit of the radar level gauge to see if it is unobstructed. Fifth, when testing the internal circuit of a radar level gauge, if the surfaces of the components are coated with insulating paint, one can use ordinary hand-sewn wires to connect them to the probes of a multimeter, thereby enabling testing of those components. Sixth, when testing radar level gauges, do not remove the control board or plug of the radar level gauge while it is still powered on; this can cause excessive reverse voltage to be generated, thereby damaging the control board and plug of the radar level gauge.
