Performance verification procedures
Use the procedures in this topic to verify the performance of the Series 2280 instruments.
Performance verification conditions
The following conditions must be met before performing these procedures:
The device under test (DUT) and all test equipment must have been operating continuously for 20
minutes in an environment that meets the operating range specifications for temperature and
humidity.
Changes to the test setup that affect the remote sense require an additional 20 minute warm-up
period.
The procedures are intended to be used in sequence. If it is necessary to partially test the DUT
using an individual test, a 20-minute warm-up period is required for the individual test.
You must connect the DUT and the test equipment to the same AC power circuit. Connect the
DUT and test instruments into a common power strip if you are unsure of the AC power circuit
distribution. Connecting the DUT and test instruments into separate AC power circuits can result
in offset voltages between the equipment, which can invalidate this performance verification
procedure.
The AC power source for the DUT must match the voltage selector switch setting located on the
bottom of the DUT.

Some procedures use hazardous voltages. To prevent electrical shock, always power off
instruments before touching exposed circuitry. Read and follow the precautions in the Safety
Precaution (on page 1-1).
