OPERATING INSTRUCTIONS
Connecting the probe to the PicoScope 4444
Connect the TA300 to the required channel of the
PicoScope 4444 via the D9 connector. The oscilloscope will
identify, power and activate the probe automatically
.
Zeroing the probe
The output zero offset of the probe may change due to thermal
shifts and other environmental conditions. Offset is controlled via
the PicoScope 6 software: open the Channel Options menu and
adjust the DC Offset con t rols. When zeroing the probe, close its
jaws and keep it away from the current-carrying conductor.
Current Measurement
1. Connect the output lead to the oscilloscope.
2. Zero the probe.
3. Clamp the jaws of the probe round the conductor, ensuring
a good contact between the closing faces of the jaws.
4. Observe and take measurements as required . Positive
output indicates that the current flow is in the direction
shown by the arrow on the probe.
