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 wrong 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.
