The NI 4050 and NI 4060 devices are full-featured digital multimeters
The NI 4050 and NI 4060 DMMs have
five input ranges available for
measuring DC voltages: 20 mV, 200 mV,
2 V, 25 V, and 250 V. Five input ranges are
available for measuring AC voltages: 20

digit DC voltage and current,
True-rms AC voltage and current, and resistance measurements.
The PCMCIA-4050, with its size, weight, and low-power
consumption, is ideal for portable measurements and data logging

with handheld and notebook computers. The NI 4060 DMMs are mVrms, 200 mVrms, 2 Vrms, 25 Vrms, and
perfectly suited for use in automated production test, portable field 250 Vrms. The NI 4060 DMMs measure
test, and benchtop electronic test. Using the NI 4060 DMMs with AC voltages to the specified accuracy

National Instruments switching modules, such as PXI-2501,
PXI-2503, SCXI-1127, SCXI-1128, or SCXI-1129, you can measure
thousands of channels, consisting of voltages, thermocouples, RTDs,
thermistors, and current loops, and keep a firm control on the cost of
your system.
as long as the voltage is within 10
percent of the selected input range. In
AC voltage ranges, the NI 4050 and NI 4060 DMMs measure the
AC-coupled True-rms value of a signal.
Measuring Resistance
Hardware
The NI 4050 and NI 4060 DMMs have five basic input ranges for both
2-wire and 4-wire (NI 4060 only) resistance measurements, and an
extended range for 2-wire measurements. The basic ranges are
200 Ω, 2 kΩ, 20 kΩ, 200 kΩ, and 2 MΩ. With extended range,
measurements up to 200 MΩ are possible. The NI 4050 and NI 4060
DMMs use a common technique to measure resistance. The
method involves sending a current through the test resistor and
measuring the voltage drop across the resistor. In the extended ohms
range, a 1 MΩ resistor is added in parallel with the test resistor.
Reading Rates
NI 4050 and NI 4060 DMMs offer multiple reading rates determined
by your resolution, function, range selections, and powerline
rejection. The maximum reading rate is 60 reading/s, once the initial
setup time affecting the first reading is passed. Please contact your
National Instruments local sales representative for more information
regarding measurement performance in your specific application.
