DC offset zero reset
T
o reset the probe DC offset to the default values, do the following:
1. Connect the probe inputs together with the hook tips.
2. Press and hold the probe BANDWIDTH LIMIT and RANGE buttons until the OVERRANGE LED on the probe begins flashing.
3. When the OVERRANGE LED remains lit (after about 4 seconds), release the buttons.
4. Press the AUDIBLE OVERRANGE button on the probe to store the value. The OVERRANGE LED on the probe turns off to confirm
that the default value for the DC offset has been stored.
5. Repeat steps 2 on page 21 through 4 on page 21 for the other range setting on the probe.
6. Perform the DC Offset Zero procedure as described in the previous section.

THDP0100 probe standard accessories
WARNING: T
o avoid risk of electric shock or fire, do not use the THDP0100 test probe or hook tip accessories on CAT III or
CAT IV circuits. Refer to the ratings tables in the Accessories section of the manual. See Voltage derating for THDP0100 probe
standard accessories .
To avoid risk of electric shock or fire, when using the THDP0100 test probe or hook tip accessories with the THDP0200 and
TMDP0200 probes, do not use on circuits above 1000 V.
Use only accessories that are rated for the application. Substitution of other accessories may create a shock or burn hazard. Keep
the probe body and accessories clean to reduce the risk of shock due to surface conduction.
Extender Leads
These leads extend the reach of the probes by 1.0 m, which allow you to reach connections as far as 3.5 m apart. Be sure to use both
extension leads so that the input leads are the same length.
However
, with longer lead length, differential noise induced into the input leads is greater. Also, because of the added inductance of the
leads, voltage measurements at frequencies above approximately 10 MHz may not be as precise. For best performance, use the 20 MHz
or lower-bandwidth filter on your oscilloscope.
The male banana-plug ends connect to the test probes that are included with the probes.
One pair of extender leads are included with the probes.

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.
