The Fan Filtercovers the air intake to keep dust and contamination out of the chassis air baffles.

The fan supplies a constant cool air flow to the inner chassis. Instructions for fan filter maintenance
are in Chapter 7.
The CALIBRATION NORMAL/ENABLE slide switch is used to write enable and disable the

nonvolatile memory that stores calibration constants. Change to ENABLE to let changes be written
into memory, and change to NORMAL to protect data in memory from being overwritten. The
switch is recessed to let it to be covered with a calibration sticker to guarantee calibration integrity.
The SERIAL 2 TO UUT connector is used to transmit and receive RS-232 serial data between the

Calibrator and a UUT. Chapter 6, "Remote Commands" tells you how to use the RS-232 serial
interface for UUT communications.
The SERIAL 1 FROM HOST connector is for remote control of the Calibrator and for transmitting

internal-constant RS-232 serial data to a printer, monitor, or host computer. Chapter 5, "Remote
Operation" tells you how to use the RS-232 serial interface for remote control.
The IEEE-488 connectorError! Bookmark not defined. is a standard parallel interface for
