See Figure4 .

Serial Port- The DB-9 connector is for interfacing the thermometer to a com-

puter or terminalwith serial RS-232 communications.

ProbeConnector - At the rear of the thermometer is the probe connector. The

probe must be connected for operation.

PowerSwitch - The power switch is located on the rear of the thermometer.

The ACpower switch turns the unit on and off. It does not control the DC

power.

AC Power - At the rear of the instrument is the removable power cord that

plugsinto a standard 115 VAC grounded socket. (230 VACoptional)

DC Power- The DC power, located on the rear of the thermometer, powers the

unitimmediately when connected.

IEEE-488 Port (optional)- The GPIB connector is for interfacing the ther-

mometer to a computer or terminalwith IEEE-488 communications.
