Setting Up the Connection
1. Connect the digital multimeter to the PC using a USB cable.
2. Power on the digital multimeter.
3. Launch the
Keysight IO Control
and the
Keysight Measurement Manager (AMM)
.
4. The
Select USB Device
dialog box will appear displaying the connected
U2741A
devices. To
start the application, select a
U2741A
device and click
OK
to establish the connection
5. The U2741A can only be operated via the USB interface. On the front panel of the U2741A, there
are two LED indicators. The power indicator lights up once the U2741A is powered on. There is a
system error if the indicator blinks after the U2741A is powered on. The USB indicator will only
blink when there is data exchange activity between the U2741A and the PC.
6. You can control the U2741A via the
Keysight Measurement Manager (AMM)
for U2741A or via
SCPI commands
sent through the USB interface from your own application programs.
7. Launch the
