3. OPERATION OPERATION 3.1. Power-on Power is supplied by the controller to which the amplifier is connected; therefore, the amplifier is powered on and off simultaneously with the controller. 3.2. Reset The reset function is used to tare/zero the output signal. To run a Reset, supply voltage from 12 to 36 V for at least 25 ms (there are no limits to longer durations) to the Reset input of the function in question. -
