1310B-X AccuRes Resistance Standard

• 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

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.
