Technical Features

  • High accuracy - fully temperature compensated.
  • Resolution of 1 part in 600,000
  • 4 ranges
  • Maximum field 3 Tesla
  • 7 digit display
  • Either RS232 or IEEE488/GPIB communications.
  • Accuracy is 0.01% of reading + 0.006% of full scale when used with MPT-141 probe.
  • Temperature range for instrument and probe 0 to 50° C
  • Because the probe characterisation information is stored in the probe assembly itself, any Group3 probe can be used with any Group3 DTM. However for full accuracy the DTM-151 should be used with a probe that has temperature compensation circuitry.
  • Two buttons on the front panel are used to select the operation of the teslameter. The following modes can be selected for the display - magnetic field, peak hold of magnetic field, AC component of field, probe temperature.
  • Digital filtering (time averaging) can be enabled to suppress short term fluctuations.
  • Several teslameters (up to 31) with serial communications can be formed into a local communications loop, all of them talked to by the one serial port on the control computer. The system can be operated in a trigger mode, where the timing of the measurements by several teslameters can be synchronised
  • Internal switches select serial data format, baud rate, device address, string terminators, filtering, gauss or tesla units, data format, service request action, EOI action, and reset system to defaults
  • Two analog outputs are available. These are a buffered version of the raw probe signal, and are not corrected for linearity or temperature.
  • All models are available without display or front buttons, for true "Black box" requirements.
  • Panel mount versions are available, and panels with correct cut-outs and mounting hardware.
