1.Mine Stray Current Tester Price Before measurement, screw the test rod wires tightly into the two binding posts, and adjust the meter pointer to the zero scale line.
2. Place the test rods connected to the binding posts on the two points to be measured (e.g., rails, water pipes, cable sheaths, coal, ground, etc.). The two test points should be on different conductors, with a distance of about 2 meters. Normally, measure every 50-100 meters, or determine test points temporarily as needed. Set the switch to the appropriate range, and the meter reading, after conversion, gives the corresponding current value.
3、 During measurement, ensure the hard alloy tip of the measuring probe makes good contact with the object under test, and the meter should be placed horizontally to ensure accurate readings.
4、 When no AC stray current is measured at a location, also test for DC stray current, and vice versa.
5、 When measuring stray voltage values, the ranges are: 50mA corresponds to 0.2V, 250mA to 1V, 1A to 4V, 5A to 20V, 10A to 40V. (That is, current value multiplied by 4 gives the voltage value)
6、 When the stray current magnitude is unknown, first set to the maximum range, then gradually decrease to the appropriate measuring range.
7、 When the measured current exceeds 5A, the instrument should only be used for short-term measurement; when it exceeds 10A, only for instantaneous measurement, to avoid burning out components and the meter due to high current.
8、 When measuring DC stray current, if the meter pointer deflects in the reverse direction, swap the test leads.
9、 When the instrument is not in use, set it to the "Off" position.
