External temperature and relative humidity
measurements
The Model 6517A can make external temperature measurements from -25°C to 150°C
using the Model 6517-TP type K thermocouple (which is a supplied accessory).
The Model 6517A can make relative humidity measurements (0 to 100%) using the Model
6517-RH humidity probe (which is available as an option).
Connections
The Models 6517-TP (thermocouple) and 6517-RH (humidity probe) connect to the rear
panel connectors labeled “TEMP TYPE K” and “HUMIDITY” as shown in Figure 1-8.
NOTE It is recommended that the thermocouple junction of the Model 6517-TP be
electrically insulated from ground and voltage potentials. Erroneous reading
will result if the thermocouple comes in contact with ground or a voltage
potential.
