The instrument can test a variety of AC and DC current, voltage, * signal, reclosing, differential and other single relay and the entire group of relay protection screen, can test the various relays pull-in voltage (current) value, release voltage ( The value of current), the closing time and the opening time of various contacts (normally open, normally closed, switching, delay) are automatically tested three times, the mean value is calculated three times automatically, and the test result can be printed.
Second, the characteristics <br> <br> intelligent relay tester because the machine uses a computer controlled character prompt operation. The machine also has a self-test error function, the machine immediately put into self-test after boot, greatly facilitate the inspection and maintenance. Such as "suction voltage", "off voltage", "normally open suction time" and so on.

5. Description of operation keys 1. Print: After the test is finished, this key can be used to print test data. Repeatedly print multiple times.
2. Time measurement: When the voltage (current) is adjusted to the rated value, press this key to automatically measure the relay pull-off time three times.
3. Measured value: Automatically test the pull-in and cut-off voltage (current) value of the relay and repeat the measurement three times.
4, right: cursor to the right.
5, upturn: number plus 1 or up menu.
6, down; digital minus 1 or down to select the menu.
7, standby: used to control the DC current output.
8. Return: Indicates to give up or return to the previous menu.
9. Confirmation: Indicates confirmation or enters the next level menu.
Sixth, test methods <br> <br> turn on the power switch, the display shows "Welcome to ....", "self-testing ....", computer self-test, self-test properly, "the self-test is completed !".
During the measurement, the type of the test power supply should be selected with the "up" and "down" keys according to the type of the tested relay, so that the status display corresponds to the type of the relay being tested. Connect the relay coil to the corresponding power output terminal and the relay contact to the input terminal.
1. Measured value: Press the "Measured value" button, the machine can measure the pull-in, disconnect the voltage (flow) value three times, and then press the "print" button to print the data.
2, timing: first find out the rated value of the measured relay, and then press the "time" button, the machine automatically points, closing the three times to measure the pull-in, disconnection time, after the end, press the "print" button to print the data .
3. Use of "Conversion" key: First adjust the DC current value, then press "Conversion" key, the DC current will be output normally, and the display value will be displayed on the second line of the screen. At this time, it can be output at the same time as other power supplies, and it can be used for the verification of relays of multiple power supplies, such as reclosing relays.
4. Time setting: Users can modify the internal clock of the instrument.
5, instrument calibration: After the instrument is used for a period of time, if the test is biased, the user can use high-grade meter to calibrate it, use "up", "down" key to adjust the internal coefficient, without opening the chassis or adjust any knob .
Seven, matters needing attention:
1, before use, please read the instructions in detail in order to avoid operating mistakes.
2. Before starting the machine, please ground it reliably to ensure the safety of people and machines.
3. After finishing a test, adjust each adjustment knob to the minimum value.
4. Intelligent relay protection tester The power of each channel of this machine shall not be used for permanent power supply; the power supply of the machine is used intermittently, and the duration of high current output shall not exceed 5 minutes.
5. Please turn off the power in time if the unit is abnormal.
6. When the device under test is switched on or off, the output may be live. Please pay attention to safety.
7. The instrument will be free for warranty and lifetime maintenance if there is quality problem within 12 months after it is sold.
