External Signal Input (Only Ext And Add); General Function - NF DP420LS Instruction Manual

11. Specifications

11.22.3 External Signal Input (only EXT and ADD)

This multiplies the input signal by the specified gain and outputs it. For ADD, the internal signal
source is added.
EXT: Output voltage (V) = External signal input (V) x Gain (V/V)
ADD: Output voltage (V) = External signal input (V) x Gain (V/V)
External signal input cannot be used for the polyphase system.
