TCP305 and TCP312 Adjustments
Figure 16:
DC gain adjustment setup for TCP305 and TCP312
Procedure
1. Press the amplifier PROBE DEGAUSS AUTOBALANCE button. Wait for
the dega
uss/autobalance routine to complete before proceeding. The routine
is complete when the indicator light turns green.
2. Connec
t the current probe to the DC current loop.
3. Perform the following steps: (See Table 29.)
a. Set the amplifier to the appropriate range setting for the probe you are
testing.
b. Set the current source output to the correct current level.
c. Enable the output of the current source.
d. Adjust the DC gain control on the probe to the expected output value
shown. (See Table 29.)

This completes the adjustments for the TCP305 and TCP312 Current Probes. Do
the appropriate performance verification procedure for the probe you adjusted,
using these procedures. (See page 19, TCP305 and TCP312 Performance
Verification.)
