with correct Windows version. The driver supports Windows7, and later
version of Windows operation system. The Mac-OS/Linux/Android are also
supported without the need of software driver
2) If your meter uses CH340 USB to Serial chip, Download and install WCH
USB to serial chip (CH340)software driver for Windows from WCH.cn
website (wch.cn/downloads/CH341SER_ZIP.html) instead. The CH340
chip driver supports all Windows versions, Linux, apple IOS and Android
devices.

program is successfully installed in your PC computer, connect the
ED85EXPlus to the PC computer by using microUSB to USB Data cable.
The ED85EXPlus will be powered by the PC through USB cable (turn off the
power switch on the ED85EXPlus to save the battery inside ED85EXPlus,
the power switch is used to control the 9V battery inside ED85EXPlus only).
Run the Teraterm program, select the correct serial port devices detected
by Teraterm to connect it to ED85EXPlus's internal USB to serial UART
bridge chip. (use Teraterm's setup/serial port command to setup the
Teraterm serial port data rate to 9600, 8bit, no parity, 1 stop).
find the HT42B534 or CH340 USB to UART Bridge device in the Teraterm,
you can use the Window's device manager in control panel/system and
security/ to check the COM port# assigned by Windows. The ED85EXPlus
is setup to send the measured data to USB serial port automatically after
powered on. The data is automatically recorded in the internal data Buffer
of ED85EXPlus all the time. You should be able to see the serial data sent
by ED85EXPlus in the Teraterm data window after selecting the serial mode
with proper serial data rate in Teraterm.
5) Use the Log function in the Teraterm to Log and save the received data
from ED85EXPlus to the Log file in PC by using the File/Log command in
the Teraterm. Teraterm will save/Log the received data in the file name
specified by you. You can rename the saved Logged/saved file
(teraterm.log by default) to xxx.csv and open it with Excel spread sheet
program for analysis/chart and documentation purpose.
6) You can halt the ED85EXPlus Data Logging/recording by HOLD button.
Release the HOLD mode will continue the automatically data recording.
7) The measured data is recorded in the internal data Buffer automatically all
the time (when the meter is not is in HOLD mode). 1000 data storage in the
data Buffer is available to store the data, then it will wrap around and
overwrite the old data when the data Buffer is full.
measured data is stored in the data Buffer all the time.
8) Currently, the RF mode with dBm, mw/m2, and V/m unit is supported for
Data Loggin/recording only. The time interval is set to 0.5sec by default
(you can change it).
