Frequently Asked Questions
1. How does the non-contact voltage feature of the TPI 270 and 275 benefit me?
The non-contact feature of the TPI 270 and 275 allows you to detect live circuits without using the test leads, which enables faster checks for the presence of voltage.
2. Which of the TPI clamp-on meters will measure temperature?
The 270 and 275 have this feature built in and the 255, 265, and 291 can measure temperature by using the optional A301 or a A312 K-type thermocouple adapters.
3. Which TPI clamp-ons can measure DC microamps?
The TPI 270 and 275 has the capability to measure DC microamps by using the test leads. This is very useful for making flame safety control current measurements. The 265 can measure DC microamps with the optional A213 adapter.
4. Does a clamp-on meter measure anything besides amps?
All TPI clamp-on meters measure AC/DC volts and resistance. Models are available with temperature, frequency, capacitance, and non-contact voltage detection capability as well as many other features. Various adapters including temperature (A301 or A312), carbon monoxide (A771), and pressure (A620/630) are available. Contact TPI for additional information.
5. Is it possible to measure AC amps on a device that uses a power cord?
Yes, to accomplish this you can use the TPI line splitter (A202). AC amps must be measured by isolating a single wire and the A202 line splitter does this without damaging the power cord.
