9902.17.33 - PXI 6-1/2 digit digital multimeters (DMM), each without recording device, not intended to be hand-held, having 6-1/2 digit of measurement accuracy, designed to provide basic measurements that may include DCV, ACV, DCI, ACI, 2 and 4 wire resistance, frequency, period, capacitance, temperature, duty cycle, counter and DC source (provided for in subheading 9030.31.00)

This HTS classification, under Chapter 99, specifically covers PXI 6-1/2 digit digital multimeters (DMMs) that do not include a recording device and are not designed for handheld use. These instruments are characterized by their 6-1/2 digit measurement accuracy and are engineered to perform fundamental electrical measurements. Key functions include measuring DC and AC voltage (DCV, ACV), DC and AC current (DCI, ACI), 2 and 4 wire resistance, frequency, period, capacitance, and temperature. Additionally, they can perform duty cycle measurements, function as a counter, and provide a DC voltage source. The "for which provision is made in subheading 9030.31.00" note signifies that while these instruments are listed here under temporary legislation, their primary classification, if not for the temporary provision, would fall under subheading 9030.31.00.

As this is a leaf node within Chapter 99, there are no further subcategories to explore. The primary distinction for this classification lies in its temporary nature, as indicated by its placement within Chapter 99. It represents a specific set of advanced digital multimeters that are subject to particular trade agreement or legislative provisions. Unlike the broad categories of live animals or agricultural products found at the root of the HTS, this entry focuses on a very specific type of electronic test and measurement equipment, differentiated by its technical specifications and intended use within a PXI modular instrumentation system.
