Page: 81 / 120

USB driver, PC can control the instrument and collect
test results over virtual serial interface.

Connecting Instrument to PC

Follow the below procedures for connection setup.

1

．

Install USB driver from CD or download the USB

drivers from www.tonghui.com.cn.

．

With a Mini-USB cable, connect one end of it to

the LCR meter and the other end to an available
USB port on PC. Press the POWER button to turn
on the meter.

．

Skip the next process when the driver has been

stalled.

．

When Windows recognize the USB connection,

PC will prompt user to install driver. The following
process is to cancel installation guide and directly
run the setup program in the setup file.

．

When completed, Windows will create a virtual

serial port and distribute a serial number. See
Windows device manager for details.
