AC/DC Oscilloscope Current Probes TT-CC Series

6. Basic Operation

Before using the probe a battery or specified power adaptor must be installed.
See "Battery and AC Power Adapter" and "Battery Installation".
WARNING Do not clamp the probe onto circuits with
voltages greater than 600 VAC (600V CAT II, 300V CAT III).
Personal injury or damage to the probe may result.
Always connect the current probe to an instrument before
clamping onto the circuit under test!
1. Connect the BNC cable to the current probe's BNC female output
connector then connect the BNC cable to the oscilloscope's BNC input.
Start by setting the oscilloscope's voltage input channel to DC and the
voltage sensitivity to 0.1 V/div.
2. Move the OFF/Range switch to the low V/A or high V/A position. The
green ON Indictor LED will light. If the green ON Indictor LED does not
light, replace the battery or use included power adaptor.
3. Use the ZERO Adjust to zero or offset the probe output of residual
magnetic DC charges.
4. Connect the probe to the circuit by opening the jaws with the Jaws
Opening Lever and clamping around the conductor (see Figure 2).
NOTE: Clamping around both the "hot" and "neutral" wires may give a
zero reading.
Remember to unclamp the probe from the conductor before
disconnecting it from your meter or instrument.
