Getting Started
Operating the
Current Probe Slide
The current probes each have a slide mechanism that opens and closes the probe
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.
The 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 o
peration of the TCP305A and TCP312A current probes is shown in
the following illustration. (See Figure 6.) 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.
