Step 2. Connect the load to the source output
Basic connections for sourcing voltage are shown in Figure 3-4 .

A safety shield is advisable whenever measurements are being made
with voltages over 30V DC. Connections for the safety shield are
shown in
Figure 3-4 . The metal safety shield must completely surround
the noise shield or floating test circuit and it must be connected to
safety earth ground using #18 AWG or larger wire.
Step 3. Turn on voltage source
Press the OPER key to turn on the voltage source output. The VOLTAGE SOURCE
OPERATE indicator will turn on.
