Six-phase relay protection tester / relay protection tester can test various AC/DC currents, voltages, signals, reclosing, differential, and other individual relays as well as complete relay protection panels. It can test the pickup voltage (current) value, dropout voltage (current) value, and the pickup and dropout times of various contacts (normally open, normally closed, changeover, delay) of various relays. Each test is automatically performed three times, the average of the three values is automatically calculated, and the test results can be printed.

Test Methods:
Turn on the power switch, the display shows "Welcome...", "Self-checking...", the microcomputer performs self-check, and after the self-check is normal, it displays "Self-check complete!".
When measuring with the six-phase relay protection tester / relay protection tester, according to the type of relay being tested, use the "Up" and "Down" keys to select the type of test power supply, so that the status display corresponds to the type of relay under test. Connect the relay coil to the corresponding power output terminals, and connect the relay contacts to the input terminals.
1. Value measurement: Press the "Value" key, the device can measure the pickup and dropout voltage (current) values three times, then press the "Print" key to print the data.
2. Time measurement: First find the rated value of the relay under test, then press the "Time" key, the device automatically opens and closes to measure the pickup and dropout times three times, after completion, press the "Print" key to print the data.
3. Use of the "Convert" key: First adjust the DC current value, then press the "Convert" key, the DC current will be output normally, and the displayed value will be shown on the second line of the screen. At this time, it can be output simultaneously with other power supplies for calibration of relays requiring multiple power supplies, such as reclosing relays, etc.
4. Time setting: Users can correct the internal clock of the instrument.
5. Calibration of the six-phase relay protection tester / relay protection tester: After the instrument has been used for a period of time, if there is a deviation in testing, users can calibrate it with a higher-level meter, adjust the internal coefficients using the "Up" and "Down" keys, without opening the case or adjusting any knobs.
