A621 Instructions
Operating Basics
WARNING. Do not c lamp the probe onto circuits with voltages greater
than 600 VAC. Personal injury or damage to the probe may result.
Always connect the probe to the instrument before clamping onto the
circuit under test.
1. Connect the probe BNC c onnector to the oscilloscope input. Start
by setting the oscilloscope channel vertical coupling to AC volts,
the vertical deflection to 0.1 V/div, and the probe to 1 mV/A.
2. Connect the probe to the circ uit by opening the jaws and
clamping around the conductor. See Figure 1. Note: Cla mping
around both the “hot” and neutral wires may give you a zero
reading.
