1. Do not clamp the current probe around any conductor, but make sure the
jaws are locked shut.
2. Press the amplifier PROBE DEGAUSS AUTOBALANCE button. Wait for
the degauss/autobalance routine to complete before proceeding. The routine
is complete when the indicator light turns green.
3. Connect the current probe to the appropriate current loop. (One-turn for the
TCP303 and 5-turn for the TCP404XL.)
4. Refer to Table 6--11 and perform the following steps:
a. Set the current source output to the correct current level.
b. Enable the output of the current source.
c. Adjust the DC gain adjustment on the probe to the expected output value
shown in Table 6--11.
