1310B AccuRes Resistance Standard

• Combines primary-level resistors with a 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 to 1 GΩ
• 0.1 Ω capable of 3 A

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.
