Using The Multimeter In Connection With A Computer - Conrad VC 350E Bedienungsanleitung

Attention!
Do not connect any voltages. The instrument can be destroyed by
this.
6.10 Using the analogue bar graph
The bar graph is easy to operate and understand. It is comparable
with the pointer of an analogue measuring instrument without its
mechanical disadvantages. It is particularly suitable for measuring
signals that change rapidly, for which the digital display is too
"slow". So the trends of a measured value change can be quickly
recognised and evaluated.
6.11 Using the multimeter in connection with a com-
puter
The multimeter is supplied together with a diskette, on which is
software for DOS and Windows 95 operation. So that the measu-
ring instrument can communicate with an IBM compatible PC, the
software must first be installed.
Note
The following installation(s) presuppose basic knowledge of the
various MS DOS commands and an available hard disk. Read the
MS DOS manual with regard to software installation, if you have
no or insufficient basic knowledge of MS DOS commands. In addi-
tion, a VGA monitor (+ VGA card in the computer) is required to
operate the software.
Step 1
1. Start your computer and activate Windows. Windows 95 (nor-
mally) loads automatically.
2. Under Windows, insert the floppy disk into the 3.5" drive (A
or B according to the installation).

3. Click on the "START" (bottom left, on the taskbar) with the
left mouse button: and then click on "RUN".
4. As a result, a dialog box appears into which "A:\Setup.exe"
should be entered. Click on OK". Follow the on-screen setup
program instructions.
5. Once the program has successfully loaded, click on "OK".
Step 2
The software for Windows 95 is now loaded. To "communicate"
with the multimeter, the following inputs/actions are now requi-
red:
a) Connect the interface lead 4-pin plug (supplied) to the RS-232
interface on the (switched off) measuring instrument. Connect
the other end of the interface lead to a free serial port on the
(switched off) computer.
b) Power up the PC. Open the START window under Windows '
95. Click the mouse pointer on the Programs menu item using
the left mouse button. Among others in the sub-directories
listed is "DMM97". Click on OK „97". Thereupon "About
Scope View" is displayed. Click on OK.
c) The menu "Scope View Main Menu" is displayed. To install or
change the hardware configuration, click on "Setup". "Scope
View Setup" appears on-screen. Enter the following infor-
mation:
Meter Model 350E
Com Port COM1, COM2, etc. (communications interface
on the PC)
Baud rate 1200 (transfer speed 1200 bits per second)
d) Having inputted the data, store the data "permanently" by
clicking on "SAVE" and then on "CLOSE" to close the window.
