CX3300 Current Waveform Analyzer
Quick Operation Guide
How to minimize the offset current
1. Perform “User Calibration”. The
offset current of the current
sensor will be minimized.
2. Perform a actual measurement
and fix the connection and the
CX3300 settings such as the
current range.
3. Perform a “Null” measurement.

3-1. Make a connection to prevent the current flow into the current sensor.
Note for connection:
- Connect either the (+) or (-) terminal of the current sensor to the stable voltage
on the DUT.
- Connect the ground lead to the circuit common of the DUT.
Remove the test lead
of the (+) terminal to
prevent the current
flow into the current
sensor
