The distance between test points for the stray current tester price is about 2 meters, and normally it is measured every 50-100 meters, or temporarily determine the test points as needed. Set the changeover switch to the appropriate gear, then the meter reading, after conversion, gives the corresponding current value
Detailed Introduction:
Stray Current Tester Price
Stray Current Comprehensive TesterUsage Methods and Precautions
1. Before measurement, screw the test rod wires into the two binding posts respectively, 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, earth, etc.). The two test points should be on different conductors. The distance between test points is about 2 meters, and normally it is measured every 50-100 meters, or temporarily determine the test points as needed. Set the changeover switch to the appropriate gear, then the meter reading, after conversion, gives the corresponding current value.
3. During measurement, ensure good contact between the hard alloy tip of the measuring probe and the object under test. The meter should be placed horizontally to ensure accurate readings.
4. When AC stray current cannot be measured at a location, also test for DC stray current, and vice versa.
5. When measuring stray voltage values, the gears are: 50mA corresponds to 0.2V, 250mA to 1V, 1A to 4V, 5A to 20V, 10A to 40V. (That is, the current value multiplied by 4 gives the voltage value.)
6. When the magnitude of stray current is unknown, first set to the maximum range, then gradually decrease to the appropriate measuring gear.
7. When the measured current exceeds 5A, the instrument should only be used for short-time measurement; when it exceeds 10A, only for instantaneous measurement, to avoid burning out components and the meter due to large 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.Stray Current TesterProduct Completeness
