Operating Instructions

Discharging the Probe Between Measurements
CAUTION
Measuring a node having a DC voltage potential charges blocking capacitors
inside of the probe. Ground the probe tip after measuring such nodes to
discharge the probe capacitors.
Failure to do this can result in damage to sensitive circuits in the DUT,
especially if it is an active device.

Grounding the probe

Proper grounding is important when making measurements with any probe. The
probe is supplied with two grounding devices: an alligator-type ground clip and a
slip-on type ground tip. Use the shortest ground path possible. Proper grounding
becomes more important as frequency increases. For optimum measurements in a
factory environment, design your circuits with ground-plane feedthroughs next to
every test point.

Retracting and extending the protective sleeve

Hold the probe wand in one hand, pointing the tip away from yourself. Grasp the
probe sleeve in the other hand and turn about 1/4 turn counter-clockwise. Now,
pull the sleeve toward you while slowly turning it counter-clockwise. The sleeve
will now retract quickly with little counter-clockwise rotation. Reverse this
procedure to extend the sleeve.
