| Power (On/Off): | Activates the remote amplifier control unit and illuminates LED. | ||
| Bridge Excitation (On/Off): | When used with a modular strain gage spinning amplifier, this turns the excitation to the bridge on or off without turning off the amplifier. This is done by inverting the polarity of the ± 15V supply pins. | ||
