TOS1

• High accuracy ±0.1% ohmmeter standard
• Rugged design for field use
• Designed to be used with large test clips or banana jack inputs
• Four terminal Kelvin – no lead compensation
• Universal standard for use with all ohmmeters

The TOS1, Transformer Ohmmeter Standard has been designed to be used with ohmmeters as a high accuracy reference resistance standard. This unique standard provides resistance measurements across a wide range for use when calibrating ohmmeters and is designed for use as a laboratory calibration standard, or as a portable check standard for field resistance verification of any ohmmeter.
