Analogic AN3100 Power supply
Model: AN3100
Category: Measurement instruments
Group: Power supply
Description: Secondary dc Voltage Standard
                                    The Secondary DC Voltage Standard is delivered fully
calibrated and ready to serve within its certified
accuracy for a duration of six months before requiring
recalibration against primary standards. After unpacking,
the line voltage selector switch on the rear panel should be
set to 115 or 230 volts, as appropriate.
The AN3100 is ready for use; however, material in this
manual will be informative and valuable for proper
instrument application.
