Adjustment Procedures
Procedure
36
Before you begin these procedures, remove the top housing using the procedure
on page 48. Leave the inner shield in place. See Figure 16 for a diagram of the
adjustment locations.
NOTE. To avoid contaminating the sensitive areas of the circuit board, do not
remove inner shield or touch the circuit board. Access all adjustments through
holes of inner shield
Connect the output of theADA400A Differential Preamplifier to the oscillo-
scope, turn the oscilloscope on, and let the ADA400A warm up for 20 minutes.
NOTE. Only TDS 400A Series oscilloscopes (TDS 460A, etc.) can display the
proper scale factor. If you are using an oscilloscope other than a TDS 400A
Series to perform these procedures, see page 2 to properly configure the scale
To convert the volts/division settings for oscilloscopes that cannot read the scale
factor from the ADA400A, multiply the volts/div setting in the procedure by the
gain setting of the ADA400A.
