Constant Voltage Output
The DP1116A has two modes for power output: Constant Voltage output (CV) and
Constant Current output (CC). The output mode of the channel is decided by a
combination of the specified voltage and current as well as the load connected to the
instrument. Neither the output voltage nor the current of the instrument can exceed
the specified values. In CV mode, the output voltage equals to the specified voltage
value; in CC mode, the output current equals to the specified current value.
For example: select the 16V/10A scale and separately set the voltage and current to
16 V and 10 A, then connect a load with 2 Ω / 300 W to the instrument. As 2 Ω × 10 A
= 20 V > 16 V, and 16 V / 2 Ω = 8 A < 10 A, so the channel output the power with
constant voltage and current from this scale: 16 V, 8 A.
Operation Steps:
1. Connect the output leads: see figure below, connect the output terminal of the
instrument with the load.

Select a proper output lead following the table below and use a lead as short as
possible.
