3000RS PRECISION RESISTANCE STANDARD OPERATION MANUAL 3000RS Precision Resistance Standard The 3000RS is a dedicated precision resistance standard. The standards do not require temperature controlled air or an oil bath making the 3000RS suitable as working standards, transfer standards as well as calibration support for the 3000 series range of multi product calibrators.
3000RS PRECISION RESISTANCE STANDARD OPERATION MANUAL Design Notes The 3000RS is built using oil filled hermetically sealed ultra high precision foil resistors from 1 Ohm to 100kOhm, and oil filled hermetically sealed ultra high precision wire wound for the 1 /10 MOhm – no adjustable resistors are used within the design of this reference.
3000RS PRECISION RESISTANCE STANDARD OPERATION MANUAL Label Reference Model Number Information Model number reference for product Serial Number Unique serial number for product Operating Notes This section details operational and environmental considerations for the 3000RS precision resistance standard. Follow these instructions when operating or storing the resistance standard. Connecting to the 3000RS CAUTION Do not apply voltages above the maximum ratings detailed below.
3000RS PRECISION RESISTANCE STANDARD OPERATION MANUAL The specifications for connections with CURRENT and VOLTAGE (SENSE) require four wire connections as standard. Use these terminal posts are detailed in the section below. For the case to act as a shield the EARTH terminal must be connected to earth ground or instrument guard at some point in a calibration configuration. When connecting two or more instruments with guards, the use of a single common earth point avoids earth loops.

3000RS PRECISION RESISTANCE STANDARD OPERATION MANUAL Care & Maintenance The only maintenance instructions for the 3000RS precision resistance reference is periodic cleaning. See below for details on the cleaning procedure and precautions for handling. Cleaning the 30000RS To keep the external enclosure of the 3000RS in good condition, clean the outer case with a soft cloth. Do not use any liquids in cleaning the enclosure – removal of surface dust is all that is recommended.
