Digital multimeters MD 9040 TRMS Industrial Digital Multimeter CAT IV / 1000 V overvoltage category and TRMS measurement of AC current and voltage are key features of the MD 9040. That’s why it is particularly suitable for performing measurements on power supply sources in the most demanding applications in the industrial sector. Its high accuracy, 2-line LCD display, diverse measurement functions, fast one-handed operation and outstanding value for money open up a wide range of possible uses. MEASURING FUNCTIONS • TRMS AC, DC voltage measurement; • TRMS AC, DC current measurement; • Capacitance measurement; • Resistance measurement; • Diode test; • Mains supply frequency measurement; • Frequency of digital signals measurement; • Continuity test (acoustic signalling). • TRMS: accurate readings on sinusoidal and non-sinusoidal signals. • Lead alert: incorrect lead connection alert. • Auto-ranging: user can switch between auto and manual ranging. • Relative zero mode: relative function for comparing the difference between signals or removing background noise. • Data Hold: data hold feature freezes the display for later view. • PC Link: test results can be downloaded to the computer via the optional PC software. • Frequency measurement: up to 1 MHz. • Safety: CAT IV / 1000 V overvoltage protection. • Easy to read: large bright 4 digits 9999 counts dual LCD display. • High level industrial testing; • High level electronic fault finding; • Field servicing; • Heav
