Operate the current probe

TCP303 and TCP404XL

slide operation

The slide operation of the TCP303 and TCP404XL current probes is shown in the
following illustration.

To operate the probe:

1.

Press the bottom of the lock button to unlock the probe.

2.

Squeeze the handle until the core is open.

3.

Insert a 5 mm (0.2 in) diameter maximum conductor size into the jaw.

WARNING.

To prevent probe damage, do not force conductors larger than 5 mm

(0.2 in) diameter into the jaw.

4.

To close and lock the probe, release the squeeze handle and press the top of
the lock button. When you are taking measurements, keep your

fi

ngers behind

the demarcations on the probe, and away from the shaded area shown above.

WARNING.

Do not connect the current probe to any wire that carries voltages or

currents that exceed the rating of the probes.
