Operating Basics
Set Up to Use Remote Sense
Use remote sensing to regulate the output voltage at the device under test. This feature lets you compensate for the voltage
drop in the leads between the power supply front-end terminals and the device-under-test. To set the remote sensing mode:
1. Remove any jumpers or shorting clip on the rear-panel terminal strip connectors between drive OUT + and SENSE +
and between drive OUT – and SENSE –.
2. Connect a pair of sense leads from SENSE + and SENSE - to the device under test.
CAUTION. To assure system stability, use jacketed, twisted-pair cables between the remote sense terminals of the
instrument and the load.
3. Connect a pair of drive leads from the drive OUT + and drive OUT - to the device under test.

Wiring in Series
By wiring Channel 1 and Channel 2 in series, you can use your power supply to provide up to 60 V to a device under test.
The following figure shows how to wire the outputs for Series operation. (See Figure 3.)
Your instrument can also be configured to read the combined voltage from two channels. See Combine metering of Channel
1 and Channel 2 when outputs are wired in series to learn how to set the instrument to measure the combined voltage.
(See page 18.)

but Channel 2 is on the far right.
