1310B AccuRes Resistance Standard

Featuring

  • Combines primary-level resistors with scanner and temperature-controlled chamber
  • Touch-screen controller shows calibration value and drift information
  • Designed as a DC calibration hub for automated calibrator and DMM stations
  • 0.1 Ω – 1 GΩ
  • 0.1 Ω capable of 3 A
Overview

The 1310B was designed to meet the requirements of automated DVM and calibrator calibration. Built around a low-thermal scanner and temperature controlled enclosure, the 1310B provides 11 high-stability standard reference resistors ranging from 0.1 Ω to 1 GΩ, covering the full range of resistance standards required for precision calibration. The 0.1 Ω and 1 Ω standards are also capable of handling the majority of current levels needed for verifying current input and output on units under test (UUTs). The system includes two external channels that function as a connection hub for auxiliary AC and DC calibration equipment.

 

Feature Benefit
11 resistors. Values range: 0.1 Ω to 1 GΩ. Complete line of decade-value standards in one temperature-controlled enclosure.
User-friendly touch screen. Includes resistor tracking and history graph.
Internal resistance elements in a temperature
controlled chamber.		 Excellent stability and extremely low-
temperature coefficients.
Single-output cable for direct plug-in. Easy operation without the requirement for
changing wires.
Calibrate calibrators and DVMs. Best stability < 2.5 μΩ/Ω/year.
Built-in 4-terminal scanner. Combines multiple instruments (resistors, air bath, scanner) into one easy-to-use instrument.
Two extra external channels. Connect to the resistance value of your choice.
Front-panel or GPIB-controlled. Simplified operation.
Internally-mounted PT100 temperature sensor . Monitor the internal oven via the front panel.
