Applent AT516L DC Resistance Meter

Description

The Applent AT516L is a high performance DC resistance (microohm) meter suitable for use with high, middle and low resistors, switch contact resistance, windings and much more.

A bench-based instrument, the AT516L is capable of performing full automatic real-time testing with measurement range of 1μΩ to 20MΩ and 0.05% accuracy. It has a 5 digit display with readings up to 30000 and maximum sampling rate of 7ms.

This DC resistance meter also has internal temperature compensation to ensure measurement accuracy, a total of 14 bins of comparator output and a standard RS-232 interface compatible with SCPI for connection to PC, PLC or WINCE (ideal for remote control and data acquisition).

Tech Specs

Applent AT516L Technical Specifications

Accuracy is calculated from the reading error (±% rdg.) determined by the measurement value and range, and the digit error (± dgt.).

Calculation Example:

Measurement value: 1Ω, Measurement range: 3Ω
Specified accuracy (from table below): ±0.5% rdg., ±5 dgt

(A) Reading error (±% rdg.): 1 [Ω] × 0.5% = ±0.005 [Ω]
(B) Digit error (± dgt.): ±5 dgt. = ±0.0005 [Ω] (at 0.0001 Ω resolution)
(C) Total error (A + B): ±0.0055 [Ω]

Applying total error (C) to the measurement value of 1 Ω gives an error limit of 0.9945 to 1.0055Ω.
