Oscilloscopes FAQs

Where do I use your oscilloscopes?

They are ideal for viewing industrial power signals, UPS systems, power supplies and PLC controls. Use anywhere a DMM is used.

Does the oscilloscopes measure capacitance?

Yes, the 440 can measure up to 400uF (microfarads).

What is the highest voltage the oscilloscopes can measure?

They can measure up to 1,000 DCV and 1,000 ACV.

What is the lowest voltage the 440 can measure?

The 440 can measure down to 0.1 millivolts on both DCV and ACV. The scope also has a volts/division setting of 0.1 volts.

How is the RS232 port used?

With the optional A402 cable and software you can acquire data and download it to a spreadsheet.

Can your oscilloscopes measure more than 10 DCA or ACA?

Yes, TPI offers a number of amp adapters to extend the range up to 1,000 amps. TPI has a wide range of optional accessories that enables the user to measure amps, temperature, pressure, or CO.

Why do you need a 20 MHz oscilloscope (460)?

To measure signals and voltage anomalies, and to look for glitches that may damage or even shutdown electronic machinery. View sine waves on power supplies, motors, and bead board circuitry. Pinpoint certain glitches on the sine wave to zero inon the problem and monitor changing patterns or distortion in electrical currents.

What are the different waveform patterns displayed on your handheld oscilloscopes?

An AC waveform known as sine wave displays voltage against time in the shape of a sine curve. The saw toothwave form displays a ramped angleand a sharp downward return to its earlier value. (Its display pattern resembles the cutting edge ofa saw.) A square waveform graphically plots a series of vertical square shapes repeated with spacing between peaks.

Why is it important to have Trend Mode?

Trend Mode is great for monitoring sudden intermittents caused by loose connections, dirt, or damaged wires. By setting the minimum and maximum parameters, you can monitor, even record the changes.

What is the purpose of triggering?

Simply zoom in on certain parts of the sine wave and “hold” to measure and monitor that particular part you are reading. A must have when searching for glitches and distortion on all measurements.
