Function
P>100 mTorr Indicator
A red light emitting diode is used as a rough pressure indicator. The LED will be
OFF below 100 milliTorr and gradually illuminates as pressure increases.
Power Indicator
A green light emitting diode is on when power is applied and the microprocessor
is working. The LED blinks if the microprocessor is not working. The LED is OFF
when no power is applied.
Address Selector
Rotate the pointer to the desired RS-485 address. The address switch value is
added to the programmed offset address (SA command).
