The remote (“slave”) function utilizes the 0-1 Vdc output signal from the master 2522 gauge display.
The slave gauge provides repeated gauge readout as displayed on the master unit. This is done utilizing
only one potentiometer. The slave can be installed at any desired location and may also be installed
with the 4-20 mA output option if required.
