TPI Multimeters FAQ
Are there amp adapters for TPI DMMs?
TPI DMMs (except for the 120) measure up to 10 amps. AC and AC/DC adapters are available.
What is continuity?
Continuity refers to testing for breaks in a wire or if it is continuous (hence, continuity). A resistance reading at or near zero indicates continuity or a solid wire. The unit of measurement for resistance is ohms.
Which TPI DMMs measure millivolts (DCmV)?
All TPI DMMs can measure millivolts. A millivolt is equal to 0.001 volt. A DMM with a 2-volt range will have resolution to .001 volt or 1 millivolt.
Which TPI DMMs measure DC microamps (DcuA) for flame safety controls?
The TPI 126, 133, 135, 153, 163, and 183 measure microamps.
Which TPI DMMs will measure capacitance (microfarads)?
The TPI 135 and 183 measure capacitance.
Is there a temperature adapter for TPI DMMs?
All TPI DMMs measure temperature using the A301 optional temperature adapter.
Is there a CO (Carbon Monoxide) adapter for TPI DMMs?
All TPI DMMs measure CO using the A701 optional carbon monoxide accessory.
Where do I use the 440?
The 440 is ideal for viewing industrial power signals, UPS systems, power supplies and PLC controls. Use anywhere a DMM is used.
Does the 440 measure Capacitance?
Yes, the 440 can measure up to 400 uF (microfarads).
What is the highest voltage the 440 can measure?
The 440 can measure up to 1000 DCV and 1000 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 the 440 measure more than 10 DCA or ACA?
Yes, TPI offers a number of amp adapters to extend the range up to 1000 amps. TPI has a wide range of optional accessories that will enable the user to measure amps, temperature, pressure, or CO.
