Digital Multimeter Pinout and Connections

Caution  Exceeding the maximum input voltage ratings, which are listed in the NI VirtualBench Specifications document, can damage the device and the computer. National Instruments is not liable for any damage resulting from such signal connections.

DMM Signal Connections

Measurement	Wiring Diagram	Range
DC Voltage		100 mV, 1 V, 10 V, 100 V, 300 V
AC Voltage		100 mVrms, 1 Vrms, 10 Vrms, 100 Vrms, 265 Vrms
DC Current ≤100 mA		10 mA, 100 mA
DC Current >100 mA to 10 A		1A, 10 A
AC Current ≤50 mArms		5 mArms, 50 mArms
AC Current 500 mArms to 5 Arms		500 mArms, 5 Arms
2-Wire Resistance		100 Ω, 1 kΩ, 10 kΩ, 100 kΩ, 1 MΩ, 10 MΩ, 100 MΩ
Voltage Across a Diode		2 V

Note  If the Digital Multimeter (DMM) always reads about 0.00 A or 0.00 mA when measuring current, the cause may be a blown fuse.
