[1] AC POWER CONNECTOR The AC power cord is inserted into this connector. The
fuse and line voltage selector are located in the connector housing.
[2] POWER SWITCH Turns the meter on and off.
[3] EXTERNAL BIAS INPUT Two banana plugs are used to input an external bias
voltage. The bias supply voltage must be floating and well filtered. Neither input
connector can be referenced to ground.
[4] EXTERNAL BIAS FUSE Protects external bias circuit from currents greater than 250
mA.
[5] RS232 DB25 This connector allows the meter to communicate as a DCE (data
communications equipment, e. g. a modem) to a DTE (data terminal equipment, e.g.,
a computer) using the RS-232C protocol. For further information, refer to the
material on remote programming in the Reference Manual.
[6] SW1 The switches set the RS232C protocol parameters. The Baud rate, word
