Except that the master unit is operating in “L” (local) state, all the slave units are in
the state of the output voltage controlled by the external voltage signal, that means the master
unit’s R/L (remote/local) selector switch is thrown to “L” position, while the switch of the
slave unit is turned to “R” position. V/C (voltage/current) selector switch is thrown to “V”
position.

On the top of the Figure is a master unit. Resistor R1 is connected to “+” output
terminal of the uppermost unit and the remote

Removing Dust and Dirt and Clean Treatment
When the panel has become dirty, wipe it 1ightly with a cloth moistured and a neutra1
soapsud, and then wipe it with a clean dry cloth. For c1eaning the inside of the instrument,
remove dust from the inside of the case and ventilation holes of the cover by using a
compressed air or the exhaust air of a vacuum cleaner. Be carefully when cleaning dust of the
