The MTS-2000 is a highly portable instrument for testing and calibrating transducers and panel meters. It has two precision AC/DC sources. One channel provides up to 150 volts RMS. The other channel is switchable, supplying up to either 150 volts RMS or 5 amps RMS. For high-voltage meters, you can operate the channels in series to get 300 volts RMS. That’s enough to test and calibrate nearly all the panel meters and transducers found in power utility substations.
