Connecting a Current Probe to the Amplifier
To connect a current probe to the amplifier input connector, align the red dot on
the probe connector with the red dot on the amplifier front panel, as shown in
Figure 1--4. Push the probe connector in to lock the connector. Do not twist the
connector. The connector locks into place when you push it all the way into the
front panel.
If you connect a probe to the w rong amplifier, (for example, a TCP312 to a
TCPA400), the NONCOMPATIBLE PROBE TYPE LED illuminates. Discon-
nect the probe and use the correct amplifier. The TCPA400 amplifier accepts
TCP3XX probes, but will only operate properly with TCP4XX probes.
To disconnect the probe from the amplifier, pull back on the connector housing
and pull the connector straight off the front panel.
CAUTION. Handle current probes with care. Do not drop a probe or subject it to
impact, or the core may crack.
Do not connect or disconnect a current probe while the probe is clamped around
a live conductor, or the probe may suffer electrical damage.

Each current probe is calibrated before it is shipped, and should not require
further adjustment. If a probe requires adjustment, refer to the Adjustment
Procedure Overview on page 6--1 or contact your nearest Tektronix Service
Center. The adjustment procedure must be performed only by qualified service
personnel.
