An important note - all manual selected push button front panel ranges must first be de-selected (popped out) prior to any RS232C remote operation.

The correct prompt from typing “V” is “620VN version 1.0 (C)opyright Amptec Research 3/16/2013”. If this prompt was not received, then the firmware of the unit is out of date and must be updated. If the correct prompt was received, but the commands in bullet 5 did not yield the correct prompt, then there is a defect in the unit.

Sect. E - General Operation and Design E-4-1. Reference Voltage Detailed Description The precision reference voltage required to do the A/D conversion is developed by IC201. The Analog Section zener voltage is attenuated to approximately - 0.5V . This voltage is applied to IC2-7 . Figures E2 diagrams A thru D shows the equivalent circuit of the analog section in 3 E-4-2. - Page 19 IC201 is equal to the non-inverting input of IC202.
