Terminal wire harness is the internal connection wire of electronic products and electrical equipment. Its function is to connect two independent circuits and transmit signals or currents in the two circuits. It can be said that terminal wires are very important to electronic products. For electronic products of different specifications, terminal wires for different purposes have different requirements, but no matter what purpose the terminal wire resistivity detection must meet the standard, otherwise it will be difficult to play a role. So how to do the terminal wire harness resistivity detection?
1. Turn on the power switch of the resistivity tester.
2. Clamp the pair of induction clamps on both sides and observe whether the reading is zero.
3. If the reading displayed by the instrument is 0, take a 1m length of the copper wire to be tested from the terminal wire and clamp the two ends of the copper wire with two induction clamps. The tested copper wire should not be in contact with any metal objects. Press the test button.
4. Observe the reading displayed by the terminal line resistivity detector, and take the reading to calculate the resistivity. The calculation method is as follows: resistivity = reading ** 0.7854 * indoor temperature conversion coefficient/1000.
