* Thermocouple data is for uncompensated inputs.
† Sensor calibration and 8001 Precision Option are not available for thermocouples. The error listed is for the instrument only.
Table 1-1 identifies the input configurations possible with this instrument. System performance with any of the inputs depends greatly on
sensor characteristics. Much of the typical data presented here is based on the Lake Shore sensor listed in each column. Other sensors
of the same type can be used with the instrument. Similar performance can be expected if the sensor sensitivities match.
