MONITOR:
Test points are made available at the rear 50-pin
connector from monitoring tube voltage, tube
current and tube filament current. Also, tube
voltage programming and tube current
programming readback signals are provided. The
test points are always positive regardless of the
output polarity, where 0 to 10V = 0-100% of
output. Accuracy is within
0.5%. All test points
have output impedance at 1Kohm. See Figure
3.3 for remote monitor interface.

2) All signals 0 - 10Vdc = 0 - 100% of specified maximum outputs.
1) Metering Circuit should be high Z type (>10 Meg) for accurate measurement.
