The National Instruments part number 777554-01 identifies the PXI-4060 PXI Digital Multimeter, a precision measurement tool designed for diverse applications including electronic desktop setups, portable field use, and automated production testing. This digital multimeter delivers accurate readings with 5½ digits of resolution across DC voltage and current, AC rms voltage and current, as well as resistance (ohms). The device includes multiple test probes equipped with safety banana plugs that comply with global safety standards such as UL 3111 and IEC 1010-1. Prior to using any non-National Instruments probes or accessories, users must verify compliance with relevant safety standards for the intended signal levels.

Equipped with an advanced Autozeroing function, the PXI-4060 mitigates the effects of temperature drift on measurement accuracy by electrically isolating the input signals, shorting the circuit to take a zero measurement that is automatically subtracted from subsequent readings. However, this functionality is not available for AC voltage, AC current, or diode measurement modes. The multimeter integrates seamlessly with external multiplexer and matrix switches, which can be triggered via two BNC connectors on the auxiliary trigger cable, allowing easy integration with National Instruments SCXI and PXI switch offerings. The maximum reading rate is 60 readings per second, achieved after the initial setup time for the first measurement elapses. Additionally, the PXI-4060 can measure the forward voltage drop across a diode (up to 2 V) under a 100 µA bias, making it versatile for various electronic testing applications.

This model operates under the NI-DMM driver software and is designed with features ensuring high reliability and performance, with a maximum working voltage of 300 V between either input terminal and earth ground and AC voltage bandwidth ranging from 20 Hz to 25 kHz. The DC current input protection is provided by a fast-fusing fuse rated at 500 mA/250 V, ensuring operational safety and reliability during measurements.
