Level voltage test frequency table is mainly used to measure the level and voltage, the frequency picker connected to the signal source, with the manual shift method can measure the size of the signal. HWSO20 addition to manual testing, there are automatic shift and manual storage level function. In the election frequency, automatic gear, just click the "frequency plus" can test a data, if you want to keep this data as long as the click "storage" button, this set of data can be stored in the meter, and the data is still power Long-term preservation, through the RS232 interface can also save the test data to the computer, you can also print out. Press "1", "0", "kHz" key to find the signal under test, click the "frequency tracking" key, the fourth line of the display shows "frequency lock", the frequency selection table will automatically capture the signal under test, The unit tracks the change in frequency of the signal under test. Frequency selection table in the automatic transmission can also automatically track the level changes, and then click the "frequency tracking" button, the display "frequency lock" will disappear, select the frequency table to restore the original state. The test method is as follows: First in the B frequency table input: "starting frequency point", "stop frequency point number", then press the "receive" button. Then input "Start frequency point", "Stop frequency point number" on the first floor oscillator, then press "Send" key. This test system will automatically send, automatically receive, automatically store, auto-complete all functions. Oil-cooled electric drum If you want to test results stored in the computer is also very simple, just press the "start frequency point", "stop frequency point", "communication" button on it. In addition, through the matching software can also test results in the form of tables or curves show or print out.
