FZY-3 Mining Stray Current Tester is a portable rectifier instrument with high sensitivity and multi-range protection circuit.Its characteristics are: wide measurement range, with a total of twenty ranges, capable of measuring AC/DC stray voltage and stray current separately, no power supply needed, safe and reliable. It is suitable for testing the current and voltage generated by steel rails, water pipes, cables, etc. in underground coal mines, preventing premature explosions and other combustion accidents caused by stray current discharge, minimizing fire sources in mines.
FZY-3 Mining Stray Current Tester Product Usage Instructions:
4. When AC stray current cannot be measured at a location, DC stray current should also be tested, and vice versa.
5. When measuring stray voltage, the gear settings are: 50mA corresponds to 0.2V, 250mA corresponds to 1V, 1A corresponds to 4V, 5A corresponds to 20V, 10A corresponds to 40V. (i.e., 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 until the appropriate measurement gear is reached.
7. When the measured current exceeds 5A, the instrument should only be used for short-term measurement; when the measured current exceeds 10A, the instrument should only be used for instantaneous measurement to avoid burning out components and the meter due to high current.
8. When measuring DC stray current, if the pointer deflects in the reverse direction, swap the test leads.
9. When the instrument is not in use, it should be set to the "Off" position.
