4000 Count True RMS DMM with waveform capabilities
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.
