The Model 061 Ambient Temperature, T-200 Ambient / Delta Temperature, 083E or 085 Relative Humidity sensors are generally used with shield. The 076B has an internal junction box that allows easy field connection of sensors without requiring soldering or potting. The internal junction box minimizes the problems that are associated with the dirt/moisture/resistance paths between the connections on exposed connectors.
Connect AC and sensor cables and route to AC power source and translator respectively. Refer to 076B-1 wiring connections. Apply power and verify that aspirator motor is operating. Check to see that sensor output is being recorded.
