Compensating the Probe (Optional)
With some TDS oscilloscopes, you can compensate the probe for
maximum accuracy. Perform this procedure only if your oscilloscope
displays the A
Ω
symbol when the current probe is connected.
1. Connect the calibrator to the probe compensation output of the
oscilloscope.
2. Close and lock the probe jaw over the calibrator loop.
3. Adjust the oscilloscope to display the signal.
4. Press VERTICAL MENU
→
Cal Probe
→
OK Compensate Gain.
0.5 A

5. Check that the displayed signal is 0.5 A
p-p
±
1%.
Repeat this compensation procedure whenever you move the current
probe to another input connector.
Measuring Signals
WARNING.
To avoid electrical shock from uninsulated
conductors, observe the following precautions:
Disconnect the power to the uninsulated conductor before
inserting the conductor in the probe jaw.
Do not apply a voltage higher than 300 V (DC + peak AC)
to an uninsulated conductor that is in the probe jaw.
Do not connect to or
remove from an
uninsulated conductor that
is HAZARDOUS LIVE.
Breakable.
Do not drop.
Use only on an
insulated wire.
The maximum continuous current that this probe can measure is 15 A
(DC + peak AC).
1. Before connecting the probe to a conductor, check the displayed
current measurement. If there is a DC offset, perform steps 3 through
5 of the
Setup Procedure
to degauss and balance the probe.
2. Close and lock the probe jaw over the conductor. For correct polarity
reading, connect the probe so that the current flow, from positive to
negative, is aligned with the arrow on the probe jaw.
3. Read the measurement.
