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

(DMMs). They feature accurate 5 ⁄
2
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
pxi4060

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.

to measure both AC and DC current. The CSM accessories include a
precision resistor that converts the current through the shunt into a
voltage measurable by the PCMCIA-4050. For measuring currents up to
200 mA or 10 A, use the CSM-200mA or the CSM-10A, respectively.
The NI 4060 DMMs have built-in current measurement capability.
Two input ranges exist for DC and True-rms AC current
measurements – 20 mA and 200 mA. For measuring currents
between 200 mA and 10 A, use the CSM-10A accessory.

Diode Testing
Software
The NI 4050 and NI 4060 DMMs measure the forward drop (up to Driver Software
2 V) across a diode. The diode is biased with 100 µA current, and
the resulting voltage drop is measured. Diode measurements are
made with a fixed range of 2 V.
All National Instruments DMMs are shipped with NI-DMM driver
software. NI-DMM is an IVI-compliant driver that exports the
complete functionality of the DMMs through an easy-to-use
application programming interface. You should use this driver if
you want to build an automated test application or integrate the
NI DMMs into your test software. NI-DMM works with LabVIEW,
LabWindows/CVI, Measurement Studio for Visual C++, and
Microsoft Visual Basic.
Calibration
The NI 4050 and NI 4060 DMMs are shipped with a calibration
certificate stating that the instrument was calibrated to NIST-
traceable standards to the levels detailed in the specifications.
These DMMs can be returned to National Instruments or a
qualified metrology lab for calibration.
Interactive Control
Every NI DMM is shipped with the DMM Soft Front Panel (SFP).
You can use the DMM SFP to quickly control the DMM without
writing a program. The DMM SFP provides access to all hardware
features except triggering and scanning.
Cables and Probes
The NI 4060 DMMs have built-in shrouded banana jacks to prevent
exposure to potentially hazardous voltages on the test probes. The
DMM kits include the P-1 Probe Set – two 1 m test leads (red and
black) with test probes.
The P-2 Probe Set, sold separately, includes two 1 m test leads (red
and black) with shrouded banana plugs on one end and a variety of
optional terminals on the other – two alligator clips (red and black) with
boots, two spring hooks (red and black), and two spade connectors (red
and black).

The banana-plug-to-bare-wire kit is a pair of banana to bare wire
plugs (one red, one black) that permits you to connect your DMM to
screw terminals for channel expansion via matrices or scanners. To
connect your NI 4060 to SCXI scanners and matrices, special cable
kits are available (SCXI-1357 and SCXI-1358). Refer to page 507 for
more information on switch cabling.

The NI 4060 DMMs work with external multiplexer/matrix switches. In
particular, the NI 4060 devices have been designed to integrate
seamlessly with National Instruments switch offerings for SCXI and
PXI. Two signals, Voltmeter Complete Trigger Output and Trigger Input,
control the switches. Access to the signals is through two BNC
connectors on the auxiliary trigger cable. On PXI, you can access the
triggers through the PXI trigger bus.
