TCP305A & TCP312A AC/DC Current Probes
TCP305A and TCP312A Current Probes are designed to work with the TCPA300
Current Probe Amplifier. These instructions briefly describe the probes. For more
information
Current Probes User Manual that ships with the amplifier.
WAR NI NG . To reduce risk of shock or fire, refer to the TCPA300/400 Amplifiers &
TCP300/400 Series AC/DC Current Probes User Manual before using the probe.
Connect and Degauss
, refer to the TCPA300/400 Amplifiers & TCP300/400 Series AC/DC
To connect the current probe to the amplifier, align the red dots on the two
connectors and gently push the probe connector in. Do not twist the connector.
To disconnect the probe, first pull back the collar and then pull out the connector.
Degauss the probe before you take measurements: Close the probe slider, press the
PROBE DEGAUSS AUTOBALANCE button on the amplifier, and then wait 5
seconds for the LED to turn green. See your amplifier manual for complete details.

Slider and Con
ductor Jaw
1. When the slider is in the closed (locked) position, you can degauss the probe.
2. Move the slider to the unlocked position to insert and remove conductors
to and from the jaw.
3. The jaw can accept a 5 mm (0.2 in) diameter maximum conductor size.
WARNING. To prevent probe damage, do not force conductors larger than 5 mm
(0.2 in) diameter into the jaw.
4. Close the jaw around the conductor and lock the s lider. When you are taking
measurements, keep your fingers behind the demarcations on the probe, and
away from the shaded area.
WARNING. Do not connect the current probe to any wire that carries voltages or
currents that exceed the rating of the probes.

ou are measuring, thereby improving high frequency response. The
The ground lead on the current probes is intended to be used in high dV/dt
environments. The probes have a grounded shield between the conductor under
test and the current sense transformer. Any capacitively-coupled current will then
flow in the ground instead of the transformer windings.
When you take high frequency measurements, connect the probe ground lead to
the probe ground connector and attach the alligator clip directly to RF ground to
improve EMI rejection at high frequencies (2 MHz and above). This will reduce
ging and help bypass capacitively-coupled RF currents which can flow into
rin
the probe cable. In some cases, it may be helpful to move the ground lead or
reposition the probe away from noise sources in the circuit under test.
