1310B-X AccuRes Resistance Standard

Featuring

  • Combines primary-level resistors with scanner and temperature-controlled chamber
  • 11 standard decade values and 6 selectable user values
  • Touchscreen controller shows calibration value and drift information
  • Designed as a DC calibration hub for automated calibrator and DMM stations
  • 0.1 Ω to 1 GΩ
  • 0.1 Ω capable of 3 A
Overview

The 1310B-X was designed to meet the requirements of automated DVM and calibrator calibration. Built around a low-thermal scanner and temperature controlled enclosure, the 1310B-X provides 11 high-stability standard reference resistors ranging from 0.1 Ω to 1 GΩ. The 1310B-X also allows users to add up to six additional resistor values to the unit. The system also includes two external channels that function as a connection hub for auxiliary AC and DC calibration equipment.

 

Feature Benefit
11 resistors values ranging from 0.1 Ω up to 1 GΩ. With (6) Additional selectable values Complete line of decade value standards in one temperature-controlled enclosure.
User-friendly touch screen. 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. Combining multiple instruments (resistors, air bath, scanner) into one easy-to-use instrument.
Two external channels. Connect to the resistance value of your choice.
Front-panel or GPIB-controlled. Simplified operation.
Internally-mounted PT100 temperature sensor. Connect to the front panel to monitor the  internal oven.
