display modes
Features
Benefits
6.5 digit resolution
Precisely measure volts, ohms and amps.
Frequency, period, capacitance* and
temperature* measurements
Save cost and bench space by replacing a multifunction DMM, counter,
capacitance meter, and temperature meter with one versatile instrument.
Patented split terminal jacks
Make 4-wire measurements with just two leads.
Trendplot™ paperless recorder mode
Plot measurement trends and graphically identify the extent of drift and
intermittent events.
Histogram mode
Discover stability or noise problems by viewing results as a histogram.
Statistics mode
View multiple statistical values such as average, min, max and standard
deviation to see how your signal is changing.
Dual display
Measure two different parameters of the same signal from one test
connection.
Single button for every function
Reduce set up and evaluation time with dedicated front-panel buttons to
access frequently used functions and parameters.
USB host port
Conveniently store data and user settings to USB memory devices using the
front-panel port.
PC Connectivity
Easily connect to a personal computer with multiple interface ports; Use NI
LabVIEW SignalExpress software to control your DMM, log data, and to
simply transfer and document your results.
The DMM4050 and DMM4040 offer up to16 measurement
functions, math and analysis modes.

Key Applications
 Design and debug of
embedded systems
 Precisely measure volts, ohms, amps,
frequency, period, capacitance and
temperature with one instrument, saving
bench space.
 Reveal signal quality issues like drift,
transients and stability problems by
viewing data as a real-time trend plot or
histogram
 Data log readings to internal memory or
USB flash memory device
 Automated Test
 Substitute for legacy bench DMMs into
existing test systems using emulation
modes.
 Remotely control using most available
application and development languages
with SCPI compatibility and drivers.
 1000 readings per second gives you
high measurement throughput.
