When the input current continuously surpasses the maximum input range, the probe sensor self-
protection will be activated. Please discontinue the measurement and allow the T3CP probe to cool
before making another measurement. Degauss and check the zero level after the probe has cooled
and before resuming measurements.
•
The sensor protection circuit may be activated by high temperature even when the continuous
current under test is below the maximum specified input.
•
When the measured current input surpasses the maximum input current range too often, the
current probe may be damaged.
•
When opening the sensor head of the probe, be sure to open it with the opening lever. If the jaw is
forced open when the sensor head is locked, the open / close mechanism and the jaw can be
damaged.

Do not open here, open via the
Lock / Unlock lever when in the
unlocked position.
Preparation before testing
•
Connect the T3CP current probe to the oscilloscope using the BNC to BNC cable.
•
Connect the T3CP probe power supply to the wall socket and connect to the T3CP current probe.
Power up the current probe and the green LED power indicator will light.
•
Set-up the oscilloscope: Ground the oscilloscope measuring channel, zero any oscilloscope
channel offset and turn the oscilloscope coupling mode to 1MΩ, DC coupled.
•
Select the T3CP current probe range according to the current to be measured. The default setting
of the T3CP probe is to select the larger current setting.
Degaussing and Zero setting
•
Connect the T3CP current probe to the oscilloscope (make sure the input impedance of the
oscilloscope is set to 1MΩ, DC coupled).
•
Ensure that the probe measurement jaw is empty and lock the probe jaw closed.
•
Press the button to degauss and set the probe to zero. The probe will be beep as an indication of
successfully degaussing and zeroing of the probe.
