Remote Monitoring Interface
Test points are made available at the 25-pin I/O
connector from monitoring tube voltage, tube
current and tube filament current. 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 of 1Kohm.

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