5.14 Usage of the Mulitmeter in connection with a
Personal Computer
1. Installation
Follow these steps for installation and operation:
1.1
Install the software on your computer system.
1.2
Connect the interface cable with the measuring unit and the com-
puter (see figure).
Hint!
Switch off your measuring unit and your computer before connection.
1.3
Now turn on your multimeter and your computer.
2. Technical Information to write your own software.
The data format consists of a frame of 14 bytes. The frames are set as fol-
lows:
O
1O
20
30
4O
W
36
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“ (= 10 Hz). In the middle sub-display the external DC input
voltage is displayed in “V“ (max. 40 V).
5. To select other output frequencies push either “UP“ or “DOWN“ button.
For frequency and connected reference number see below:
0.010 KHZ
= 10 Hz,
reference no. 0
0.050 KHz
= 50 Hz,
reference no. 1
0.060 KHz
= 60 Hz,
reference no. 2
0.100 KHz
= 100 Hz,
reference no. 3
0.400 KHz
= 400 Hz,
reference no. 4
1.010 KHz
= 1010 Hz,
reference no. 5
2.021 KHz
= 2021 Hz,
reference no. 6
4.042 KHz
= 4042 Hz,
reference no. 7
8.084 KHz
= 8084 Hz,
reference no. 8
10.24 KHz
= 10240 Hz,
reference no. 9
Hint!
In mode signal output, the function modes and auto-power-off do not
work.
Attention!
Never short the output of the signal generator, as the output terminal
and the meter could be destroyed.
