THDP0100 Probe Accessory Kit
Kit includes one pair of each of the accessories shown on the following pages:
•
Test Probes (TATP)
• Small Hook Tips TASH)
• Large Hook Tips (TALH)
Reorder Tektronix part number: 020-3070-xx
T
est Probes (TATP)
Use the test probes to browse multiple test points or to connect the test leads to the hook tips.
1. The test probe tip is a 6-32 threaded post that accepts the large and small hook tips provided with the probe.
2. The finger guard provides protection when the hook tips are not being used. Keep your fingers behind the finger guard whenever
possible to reduce the risk of a shock from the circuit under test.
3. Connect the back end of the test probe to the input test leads of the probe.
Maximum ratings: 2300 V CAT I. See the Specifications for the Over-V
oltage Transient (OVT) rating for the probe that you are
using. Typical characteristics on page 40.
1000 V CAT II
WARNING: T
o prevent arc flash, use caution when probing circuits with raised components. Avoid getting the metal shell between
components of different potentials. Use the small hook tip (TASH) for probing in hard to reach areas.
WARNING: To prevent arc flash, do not use the test probe or hook tips on CAT III circuits. To probe CAT III circuits, use the
AC280-FL, AC283-FL, or AC285-FL accessories.

Small Hook Tip (TASH)
Use the small hook tip for making connections to small conductors such as component leads.
Screw the small hook tip onto the T
ATP test probe. To use the hook tip, hold the probe body and pull the tip shield back. Hook the tip onto
the circuit and release the shield.
WARNING: T
o reduce the risk of shock when measuring voltages above 1000 V, always keep your fingers behind the tactile
indicator.
Maximum ratings: 2300 V CAT I. See the Specifications for the Over-Voltage Transient (OVT) rating for the probe that you are
using. Typical characteristics on page 40.
1000 V CAT II
Large Hook Tip (TALH)
Use the large hook tip when working with larger components such as bolt terminals and bus bars typically found in power distribution
equipment. Screw the large hook tip onto the T
ATP test probe and then clamp the hook tip onto the circuit.
WARNING: T
o reduce the risk of shock when measuring voltages above 1000 V, always keep your fingers behind the tactile
indicator.

The THDP0100 probe can be used with these accessories at the reduced voltage levels listed in this table.
When using the TP175 test probes in CA
T III circuits, the tip must be in the retracted position to prevent risk of arc flash. The exposed
metal tip is about 3.7 mm (0.15 in) in the retracted position.
