FEATURES
-
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.

The following specifications refer to DTM-151 with LPT-141 probe (standard size probe).
DTM-152 WITH LPT-141 PROBE (LIMPET PROBE)
Four ranges, selectable from front panel:
1. 0.3
2. 0.6
3. 1.2
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.
