Getting Started
Connecting a C
urrent Probe to the Amplifier
To connect a current probe to the amplifier input connector, do the following and
refer to the illustration. (See Figure 4.)
1. To connect the probe, align the red dots.
2. Push the probe connector in. Do not twist the connector.
3. To disconnect the probe, pull back the collar.
4. Pull out the connector.

CAUTION. Handle current probes with care. Do not drop a probe or subject it to
impa
ct, or the core may crack.
Do not connect or disconnect a current probe while the probe is clamped around a
li
ve conductor, or the probe m ay suffer electrical damage.
If you connect a probe to the wrong amplifier, (for example, a TCP312 to a
TC
PA400), the N ONCOMPATIBLE PROBE TYPE LED illuminates. Disconnect
the probe and use the correct amplifier. The TCPA400 amplifier accepts TCP3XX
probes, but will only operate properly with TCP4XX probes.
Each current probe is calibrated before it is shipped, and should not require
further adjustment. If a probe requires adjustment, information is available in the
service manual. The adjustment procedure must be performed only by qualified
service personnel. Contact your nearest Tektronix Service Center if you need
more assistance.
