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.

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

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.

THDP0200 and TMDP0200 probe standard accessories

The standard accessories that connect directly to your circuit are shown below

, and are described on the following pages.

WARNING: T

o reduce risk of shock or fire, do not exceed either the voltage rating or category ratings of the probe or the probe

accessory, whichever is the lesser of the two. Use only the accessories provided with the probe.

To avoid electric shock when using the probe or accessories, keep your fingers behind the finger guard of the probe body and

away from the shaded area shown in the accessory illustrations below.
