The user should become familiar with the furnace back panel, front panel, and

constant temperature block assembly.

6.1 Back Panel

The back panel (Figure 1) features the PowerEntry Module (PEM) that con-

tains the power cord socket, the power switch, and the heater voltage switch,

theserial port, and the fan.

Power Cord - On the back of the calibrator is the removable power cord inlet

thatplugs into an IEC grounded socket.

PowerSwitch - The power switch is located on the power entry module

(PEM). The PEM also houses the fuses and the dual voltageselector. The PEM

and Heater VoltageSwitch allow the unit to be field switchable for 115 VAC

(±10%) or 230 VAC(±10%) operation.

Heater VoltageSwitch - To be used only when changing the input voltage.

(See Section 7.2 for instructions.)

Serial Port- A DB-9 male conn ector is present for interfacing the calibrator to

a computer or terminalwith serial RS-232 communications.
