Tektronix 4000 Series: 5½- and 6½-Digit Multimeters
The 5½-digit DMM4020 and 6½-digit DMM4050 and DMM4040 broad purpose bench multimeters deliver a comprehensive range of functions to meet your most demanding measurements on the bench or in a system. These digital multimeters perform the functions you would expect to see in a multifunction DMM, including measuring volts, ohms, amps, and frequency measurements. The DMM4050 adds temperature and capacitance for greater versatility.
Features | Benefits |
| Choice of 5½- or 6½-digit resolution | Makes it unnecessary to pay for higher resolution than the application requires |
| True RMS (AC, AC + DC) measurements | Ensure high measurement integrity |
| 2×4 ohms 4-wire measurement technique | Allows performing 4-wire resistance measurements with excellent resolution and accuracy using only two leads instead of four. |
| Temperature and capacitance measurements (DMM4050) | Provide a combination of measurements few DMMs can offer |
| TrendPlot™ paperless data recorder mode (DMM4040/4050) | Plots the trend of a measured value over time graphically |
| Measurement statistics (DMM4040/4050) | Calculates both the average and standard deviation of a measurement, as well as tracks the minimum and maximum measured values, with the push of a button |
| Histogram mode (DMM4040/4050) | Displays the distribution of measurement results |
| Includes safety test leads, RS232 to USB adapter cable, and three year standard warranty |
