System Operation

Series 1700 Thermocouple dataloggers record low-level millivolt thermocouple signals. The system automatically processes these signals and references them to the logger's on-board cold junction temperature sensor to produce accurate temperature readings.Two types of Series 1700 dataloggers are available: The narrow range "N" series provides high precision and exceptional low-temperature performance; the wide range "W" series provides a broader temperature measurement range ideal for high temperature applications. The following two charts detail the input specifications , measurement ranges, and rated accuracies of these two series of units.

Datalogger Inputs

1700 Series Type	1700 Series Models	No. of Channels
		Total	CJT	Thermocouple
