4-1-5. External Resistance Control - Overview
Description External resistance control of the CC, CR, CV and CP
modes is accomplished using the J1 on the rear panel.
A resistance of 0kΩ~10kΩ is used to control the input
current, voltage, resistance or power on the LSG-H
Series.
The input can be configured to vary in proportion to the
external resistance or the inverse. See page 137 (
4-1-6.

) for more details on
proportional and inverse resistance control.
Connection When connecting the external resistance source to the J1
connector, use a ferrite core and use twisted pair wiring.

Note
Use resistors with minimum residual resist
ance of 50Ω or
less.
Note for proportional control:
Do not use swtiches that switch between fixed
resistances.
Please use continuously variable resistors.
Exceeding 11.8kΩ will cause an EXT.OV alarm message
which will reset the voltage output to 0 until the external
resistance is reduced back down
below 11.8kΩ.
