Cropico MTS Resistance Standard
The Milliohmmeter Test Standards are designed for the simple and easy calibration of low resistance ohmmeters and Kelvin / Thomson bridges. The true four terminal resistance values are switch selected and provision is made for + and - full scale values. A four terminal zero value may also be selected, thus making zero and full scale calibration of instruments simplicity itself. Two models are available, the MTS1A which has 11 values from 1 mohm to 100 kohm and the MTS2 which has 10 values from 400 micro-ohm to 400 kohm, 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 aluminium case with tilt handle. The internal standards are manufactured from premium quality resistance wire with low temperature and load coefficient. For the selection of the standards, a special switch of our own construction is used ensuring a long and trouble free operating life. The units are supplied complete with a calibration certificate.
