Category (CAT) ratings and voltage or current rating. Do not apply a potential to any terminal, including the common terminal, that exceeds the maximum rating of that terminal. Do not use the probe anywhere beyond the tactile barrier. A621 Instructions... - Page 8 Do not connect a current probe to any wire that carries voltages, current, or fequencies above the current probe rating. The tactical barrier is located at the base of the jaw. Refer to the A621 current probe figure in the section of this document.

1000 amps RMS on Tektronix TDS, TAS, or general purpose oscilloscopes. The A621 is especially useful where the display and measurement of distorted current waveforms and harmonics is required. The A621 is also compatible with DMMs by using the BNC- to-banana plug adapter (see Replaceable parts on page 12). -
Page 16: Operating Procedure
Refer to the following figure. NOTE. Clamping around both the “hot” and neutral wires may give you a zero reading. Figure 2: Connecting the A621 (Remember to unclamp the probe from the conductor before disconnecting it from your meter or instrument.) Adjust the probe range and oscilloscope channel as necessary to get a clear view of the signal. - Page 17 To increase the measurement sensitivity of the A621, loop additional turns of the wire under test through the jaws. See Figure 3. The sensitivity of the A621 will be multiplied times the number of loops in the jaws. For example: 10 mV/A X 4 turns = 40 mV/A.
