The Seaward MTS1A milliohmmeter's test standards are designed for the simple and easy calibration of low resistance ohmmeters and Kelvin / Thomson bridges.
The 4 terminal resistance values are switch selected and provision is made + and - full scale values. A 4 terminal zero value may also be selected, thus making zero and full scale calibration of instruments simplicity itself.
The MTS1A which has 11 values from 1 milliohm to 100 kilo ohm, making it ideally suited for the calibration of digital instruments with a long scale length of 4000 or 6000 count.
The test standards are housed in a rugged bench portable aluminum case with tilt handle. The internal standards are manufactured from premium quality resistance wire with low temperature and load coefficients. The units are supplied complete with a calibration certificate.
