Sampling Heads

CSA 803C Service Manual
This procedure shows the setup and lists the test steps for calibrating Loop
Gain and Offset Null. Note that this is an optional enhanced accuracy proce
dure and it fine tunes internal channel processing circuitry in conjunction
with any operational sampling head type being used (the 067-1413-00
calibration head is a service device and does not require system calibration).
This procedure also initiates a built in CSA 803A program which causes the
mainframe to remember which sampling head type was used in the calibra
tion. In this way, pre calibrated heads can be interchanged without requiring
recalibration.
