Among them, A, B, C represent single-phase measurement, Xrepresents three-phase simultaneous measurement.
l Compensation Angle: The adjustment method is the same as above. Generally, the influence of interphase interference is about 2°~5°. Due to the difficulty in accurately calculating the interference, hard compensation is generally not recommended, but it is set to 0.0°. According to the regulations, the data change trend over a period of time can be compared longitudinally. If you need to adjust the side-phase correction angle, refer to the relevant sections in the "Measurement Principle" later. If three-phase simultaneous measurement is selected, the angle is automatically compensated.
l Date: The adjustment method is the same as above. Use the "Function" key to select the item to adjust: year, month, day, hour, minute, second, and use the "Increase" and "Decrease" keys to adjust. After all adjustments are completed, press "OK".
l Mode: Press "OK" to switch among wired, inductive, and wireless modes.
l View: Press the "Function" key to move the cursor to "View", then press "OK" to enter (as shown in Figure 6); press the "Increase", "Decrease", and "Function" keys to select the data to view, and press "OK" to display that set of data.
l Measurement: Press the "Function" key to move the cursor to "Test", then press "OK" to enter measurement, and the measurement screen shown in Figure 7 appears.
Display: Switch the display screen to show all test information or a brief display. If it is three-phase simultaneous measurement, press "Increase" and "Decrease" to cyclically display the information of the three phases.
Print: Can print the measured data, but does not store it.
Storage: Store the current data. Select the storage location for the data and press "OK" to save.
Exit: Exit the measurement and return to the system main menu.
7. Data Upload: Install the data communication packaging software provided with the instrument onto the computer, and use a serial communication cable to connect the instrument to the computer's RS-232 serial port.
