ZC-650 loop vector analyzer adopts button type operation, can automatically switch range, realize large capacity storage, and can display vector diagram. It is very suitable for electric energy measurement, power consumption inspection, power inspection, substation maintenance, relay protection and other differential detection and start-up test.
When using ZC-650 loop vector analyzer, the basic operation method is as follows:
1. Turn on the instrument
When the instrument is off, press and hold the power on key for about 3 seconds, and the instrument will be powered on. The instrument first displays the "boot interface" for about 8 seconds, and then switches to the "main menu page", as shown in Figure 1
Figure 1
2. Instrument shutdown
When the instrument is on, press and hold the power on key for about 3 seconds, and the instrument will shut down.
3. SD card insertion
Place the SD card on the lower side of the instrument. Insert the copper electric shock side of the SD card downward and gently insert it. Push the SD card inward with the fingernail of the thumb. After the SD card just falls into the card slot and a weak "click" sound is heard, the insertion of the SD card is completed.
4. SD card pull out
Use your thumb's fingernail to top the SD card. After hearing the weak "click" sound, move your finger away. The SD card will automatically pop out of the slot, and then take the SD card out of the instrument.
5. Plug in and out under power on state
The plug-in method is the same as above. Before the SD card is inserted, the SD card icon of the instrument is displayed as an exclamation mark, which indicates that the instrument has not detected the SD card. About 1 second after the SD card is inserted, the SD card icon of the instrument will change to SD, indicating that the instrument has detected the SD card.
6. Use external DC power supply
ZC-650 loop vector analyzer can use external DC power supply when it is on or off. When it is on, it can charge the battery while supplying power to the instrument. When the instrument is off, only battery power is supplied by external DC power supply. In the charging state, the LED beside the power socket of the instrument is always on.
7. Access to DC power supply
Insert one end of the power cord into the socket marked DC 5V at the bottom of the instrument, and plug the other end of the power cord into an AC socket.
8. Disconnect the DC power supply
Pull out the end of the power cord connected to the AC socket. Insert the power cord into the other end of the meter and pull it out.
9. Selection of measurement function
The functions of the instrument are shown in Figure 1, wireless telemetry, three-phase volt ampere meter.
After the instrument is turned on, enter the "main menu" page. In the "main menu" page, use the ←, → direction keys to move the selection box on the screen to the required function, and press enter to enter the function.
