Do Not Work Alone

Do not work alone when working with high voltages.

Inspect the Probe

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 spilled on the probe.
In air temperatures exceeding the specified operating temperatures.
In atmospheric pressures outside the specified altitude limits or where the surrounding gas is not air.

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.

Introduction

Overview

The TT-SI 7002 differential probe allows safe, accurate measurement between two voltage points where neither point is referenced to ground. The probe offers both a 25 MHz bandwidth for the x50x and x200 attenuation settings and 15 MHz bandwidth for the x20 attenuation setting. Compatible with oscilloscopes from all major manufacturers, the probe is exclusively powered by the included 9 V power adapter.

User manual

Using the Probe

Symbol 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.

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.

Inspection Procedure

Connect the BNC output connector to the vertical input of the oscilloscope.
Power on the probe.
Set the attenuation setting on the oscilloscope to match the probe.
Connect the input of probe to a function generator. Then select a square-wave output of 10 V amplitude and 100 kHz frequency.
The square-wave will be displayed on the screen of the oscilloscope. This indicates the probe is working properly.

Note that the oscilloscope should show the same voltage and frequency as the function generator.

Getting Started

Connect the BNC output connector to the vertical input of a general purposed oscilloscope. The oscilloscope must have a ground referenced.
Connect power adapter.
Select the proper attenuation ratio. When measuring signals below 70 V, switch the attenuation ratio to x20 in order to get higher resolution and less noise ratio. For voltages up to 175 V, set the attenuation ratio to x50 and for voltages up to 700 V set the attenuation ratio to x200.
The power indicator LED should turn on.
Plug the supplied grips onto the test leads and connect the circuit under test.

Vertical Scale on Oscilloscope

The actual vertical scale of the oscilloscope is equal to the attenuation factor multiplied by the range of vertical scale selected on the oscilloscope. For example, with the probe on factor x20 and the oscilloscope on 0.5 V/div, the real vertical scale is 20 x 0.5 = 10 V/div. With the probe on x200, the real vertical scale is 200 x 0.5 = 100 V/ div. These values apply when the oscilloscope is set to the typical 1 MΩ impedance input. When the scope is set to 50 Ω input, the actual vertical scale will be doubled: 20 V/div for the x20 setting and 200 V/div for the x200 setting.

Scope Input Impedance| Probe Attenuation Setting| Actual Attenuation Setting| Vertical Scale Reading on Oscilloscope| Actual Vertical Scale of the Oscilloscope
---|---|---|---|---
1 MΩ| x20| x20| 0,5 V/div| 10 V/div
1 MΩ| x50| x50| 0,5 V/div| 25 V/div
1 MΩ| x200| x200| 0,5 V/div| 100 V/div
50 Ω| x20| x40| 0,5 V/div| 20 V/div
50 Ω| x50| x100| 0,5 V/div| 50 V/div
50 Ω| x200| x400| 0,5 V/div| 200 V/div
