Loop Resistance Tester with Printer (150A) Parameter Panel Structure

Operating Instructions
1. According to the four-wire measurement method, connect the test object to the instrument panel using the dedicated test leads. Note that the voltage measurement leads should be connected inside the current output leads.
2. Connect the AC220V power supply (note: the third wire of the power input, i.e., the protective ground, must be connected to the earth), press the power switch. At this time, the ammeter and resistance meter display "000" (one digit fluctuation is allowed).
3. Press the measurement switch, adjust the current output knob (clockwise) until the ammeter displays "100.0", then read the number on the resistance meter, which is the resistance value of the test object, and record it. (If "1" is displayed, it indicates the measured loop is over-range).
4. After testing, adjust the current output adjustment knob (counterclockwise) to the minimum, reset the measurement switch, and then turn off the power switch.
5. To repeat the test, simply reset the measurement switch, re-clamp the test clamps, and press the measurement switch again.
