Background
The current tester is a portable rectifier instrument with high sensitivity and multi-range protection circuit. The method is characterized in that: the measuring range is wide, twenty measuring ranges are provided, the alternating current and direct current stray voltage and the stray current can be measured respectively, a power supply is not needed, and the method is safe and reliable. The main methods for measuring high-frequency current include a pyroelectric method and a bolometer method. The thermoelectric method can be used for measuring direct current, low frequency and high frequency current. When measuring alternating current, sending a measured current signal from the left end, and recording an indicator value; then, the direct current is input to obtain the direct current value which is equal to the measured alternating current value when the same indicating value is obtained. This dc current must be calibrated to ensure high accuracy. The core of the thermoelectric method circuit is a thermocouple, in order to eliminate the forward and reverse errors of the thermocouple, the wiring directions of two ends of the thermocouple are required to be changed when the direct current is measured, and then the average value of the two times is taken. The method has wide range of about 10 < -3 > to 102 amperes; the accuracy is high, can reach +/-10 < -5 >, and the method is the most used method. The bolometer method: by using the characteristic that the resistance value of the radiant heater is only related to the applied power and not related to the frequency, a high-frequency voltage is measured by using a direct current instead of a high-frequency current by using a radiant heater bridge circuit, and then the current is obtained by using the voltage and the resistance.
