Operating steps of handheld circuit resistance tester

A handheld loop resistance tester is a tool used to measure the resistance value in a circuit. Here's how it works:

1, first of all, confirm that the tester battery is installed and fully charged. If the battery is lower than the normal operating voltage, it needs to be replaced or charged.

2, Turn on the tester's power switch, usually located on the side or top of the instrument, depending on the instrument model may vary.

3, then, select the appropriate measurement range. The loop resistance tester usually has multiple measuring ranges, and the appropriate range can be selected according to the resistance value of the circuit to be tested. Some instruments automatically select the best range.

4. Connect the test probe of the tester to the circuit to be tested. Typically, a test wire acts as the probe, and a connecting clamp can secure the probe to the circuit.

5, when the tester is connected to the circuit, read the resistance value on the display screen. Some instruments will display resistance values directly, while others may need to press the "Test" or "Measure" button to obtain results.

6, if you need to continuously measure the resistance value of multiple points, you can move the probe of the tester and repeat step 5. Some may need to press the "Test" or "Measure" button to get the result.

7. After completing the test, turn off the power switch of the tester and disconnect the probe from the circuit.

Please note that each model of handheld loop resistance tester may have slightly different operating procedures, so please refer to the instruction manual or relevant instructions before use. At the same time, make sure to follow the safety operation specifications during the measurement process to avoid electric shock or other accidents.
