Switch setting from POWER with the Adaptor connected. Serious injury and
meter damage can result.
4. The meter always memorizes the last input values of cost per hour, KW/H,
and accumulated costs that were measured.
8. CMOS Signal Output
Your meter is equipped with a “Function Generator” which supplies outputs of ten preset
frequencies with a voltage max. of 3.3V. To “tap off” the signal, insert the enclosed
signal adaptor into the capacitor socket, observing the correct polarity. The other end of
the adaptor has two small alligator clips. To change the multimeter into a signal
generator and to select the output frequency, follow these steps.
1. Select “SIG OUT” with the rotary function switch.
2. Connect the optional signal adaptor to the capacitance measuring socket of
the multimeter.
3. Turn on the multimeter
4. In the basic function mode, the reference number is displayed in the left sub-
display, the main display will show the respective frequency “0.010 KHz
(=10Hz). In the middle sub-display the external DC input voltage is displayed
in “V” (max. 40V).
5. To select other output frequencies use the UP/DOWN keys. Refer to the list
below for frequency and reference numbers.
0.010 KHz = 10Hz, reference no. 0
0.050 KHz = 50Hz, reference no. 1
0.060 KHz = 60Hz, reference no. 2
0.100 KHz = 100Hz, reference no. 3
0.400 KHz = 400Hz, reference no. 4
1.010 KHz = 1010Hz, reference no. 5
2.021KHz = 2021Hz, reference no. 6
4.042KHz = 4042Hz, reference no. 7
8.084KHz = 8084Hz, reference no. 8
10.24kHZ = 10240Hz, reference no. 9
Attention: Never short the output of the signal generator. The output terminal and the
meter could be damaged.
9. PC INTERFACE FEATURE
9.1 Hardware Setup
Connect the supplied RS-232C cable between the meter’s com port and the computer’s
serial port. Power the meter and the computer and then load the software.
9.2 Software for PC Interface
Two data acquisition programs are included: a DOS version (ScopeView) and a
Windows version (MultiView).
9.2.1 Using the DOS Software
Follow these steps to install and run the MS-DOS software.
1. Insert the supplied diskette in your computer’s 3 ½-inch floppy drive.
2. Create a directory on your hard disk . For example, to make a directory
called METER type.: cd \ (ENTER) then, type md METER (ENTER)
3. Change to the directory you just created. For example, if the directory is
METER, type: cd \ METER (ENTER)
4. Copy the files from the GRAPHIC sub-directory on the supplied program
floppy disk to your hard disk. For example, type: copy a:\GRAPHIC c:
5. To run the program, type METEX (ENTER) Follow the on-screen help for
specific operating instructions.
