A
CAUTION
condition, which, if not followed correctly, could result in damage to or destruction
of parts or the entire product.
Do Not Work Alone
Do not work alone when working with high voltages.
Inspect the Probe
statement calls attention to an operating procedure, practice, or
Inspect the probe and accessories for cracks and frayed or broken leads before each
use. If defects or damages are noted, DO NOT USE the probe.
Dry Conditions
Hands, shoes, floor, and work bench must be dry. Avoid making
measurements under humidity, dampness, or other environmental conditions
that might affect safety.
Do Not Remove the Probe’s Casing
Removal of the probe’s casing may expose you to electric shock. If necessary,
disconnect the inputs and outputs of the probe before opening the case.
Hazardous Contact
To avoid injury, remove jewelry such as rings, watches, and other metallic objects. Do
not touch exposed connections and components when power is present.
Unexpected Charges
Hazardous voltages may be present in unexpected locations in circuitry being
tested when a fault condition in the circuit exists.
Capacitors inside the instrument may retain a charge even if the instrument is
disconnected from its source of supply.
Use Only in Office-Type Indoor Setting
The probe is designed to be used in office-type indoor environments.
Do not operate the probe:
•
In the presence of noxious, corrosive, flammable fumes, gases, vapors,
chemicals, or finely-divided particulates.
•
In environments where there is a danger of any liquid
•
In air temperatures exceeding the specified operating temperatures.
•
In atmospheric pressures outside the specified altitude limits or where the

Not for Critical Applications
This probe is not authorized for use in contact with the human body or for use as a
component in a life-support device or system.
Do Not Substitute Parts
Do not install substitute parts or perform any unauthorized modification to the
instrument.
Only Qualified Personnel
Only qualified personnel should use this probe. This differential voltage probe is
designed to be used by personnel who are trained, experienced, or otherwise
qualified to recognize hazardous situations and who are trained in the safety
precautions necessary to avoid possible injury when using such a device.
Observe Maximum Working Voltage
Do not use any probe above its maximum working voltage ranges. See
specifications on page 7.
Use Proper Power Source
Do not operate this probe from a power source that applies more than the voltage
specified.
Must be Grounded
This probe is grounded by the shell of the BNC connector through the grounding
conductor of the power cord of the measurement instrument. Before making
connections to the input leads of this probe, ensure that the output BNC connector is
attached to the BNC connector of the measurement instrument, and that the
measurement instrument is properly grounded. Whenever it is likely that the ground
protection is impaired, you must make the instrument inoperative and secure it
against any unintended operation.

Definitions
Measurement Category II (CAT II)
refers to local-level electrical distribution, such as that provided by a standard wall
outlet or plug-connected equipment. Examples of CAT II measurements would be
household appliances, portable tools, and similar modules.
Measurement Category III (CAT III)
refers to measurements on hard-wired equipment in fixed installations, distribution
boards, and circuit breakers that form part of a building wiring installation. Other
examples are wiring, including cables, bus bars, junction boxes, switches, socket
outlets in the fixed installation, and stationary motors with permanent connections to
fixed installations
Pollution Degree 2
refers to an operation environment where normally only dry, non-conductive pollution
occurs. Temporary conductivity caused by condensation can be expected.
Working CAT rating is equal to that of the lowest rated element
within the test set-up.

1 Introduction
Overview
The TT-SI 8000 differential probe series allows safe, accurate measurement between
two voltage points where neither point is referenced to ground. The probes are
designed for high sensitivity measurements up to 200 MHz bandwidth and up to
7000V differential voltage. The probes are compatible with oscilloscopes from all
major manufacturers.

2 Using the Probe
WARNING
At the time of powering on the probe, the input leads must not be connected
to an item to be tested. Never operate the probe with the case open.
CAUTION
This probe is used to carry out differential measurements between two
points on the circuit under test. This probe is not designed for electrically
insulating the circuit under test or the measuring instrument.
Getting Started
1. Connect the BNC output connector to the vertical input of a general purposed
oscilloscope. The oscilloscope must have a ground referenced.
2. Connect power through USB or USB-adapter.
3. LED’s will turn on.
4. The default factory setting is high attenuation ratio, FULL bandwidth and audible
alarm is on. The probe has an automatic memory function, so it saves the state
before power off.
Test Procedure
1. Connect the BNC output connector to the vertical input of the oscilloscope.
2. Set the attenuation setting on the oscilloscope to match the probe setting.
3. Connect the input of probe to a function generator. Then select a square-wave
output of 10 V amplitude and 100 kHz frequency.
4. The square-wave will be displayed on the screen of the oscilloscope. The
oscilloscope should show the same voltage and frequency as the function
generator. This indicates the probe is working properly.
