Operating the
Current Probe Slide

jaw. This allows you to clamp the probe around a conductor under test. The slide
must be locke
d closed to accurately measure current or to degauss the probe. If a
probe is unlocked, the PROBE OPEN indicator on the amplifier will light.
WARNING. Do not clamp the TCP305 or TCP312 current probes around
uninsulated wires. Damage to the probe or personal injury may result. Only use
the TCP305 or TCP312 current probes on INSULATED wires.
The TCP303 and TCP404XL current probes can be used to measure current on
uninsulated wires. However, the circuit must be de-energized when connecting or
removing the current probe.
The slide operation of the TCP305 and TCP312 current probes is shown in the
following illustration. (See Figure 5.) To open the probe, pull the slide back
until the jaw is open. To lock the probe, push the slide forward until the detent
snaps
into place.
