Constant-Current (CC) Control with External Voltage or Resistance

Introduction

The current output can be controlled using an
external voltage or external resistance through
the connector J3 (EXT CONT) on the rear panel if
external control is selected.

External Resistance and External Voltage Control
Pins for current control:

CH1: Pins 15 and 16 (COM)
CH2: Pins 6 and 7 (COM)
