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-152 should be used with a probe that has temperature compensation circuitry.
Digital filtering (time averaging) can be enabled to suppress short term fluctuations.
External DIP switches for device hardware address.
One (1) analog output are available. These are a buffered version of the raw probe signal, and are not corrected for linearity or temperature.

DTM-152 WITH LPT-141 PROBE (LIMPET PROBE)
Four ranges, selectable from front panel:
4. 3.0 tesla full scale
Note: Resolution depends on the range selected, and whether the digital filtering is enabled.
Note: Resolution available at the serial port is greater than that of the display.
