*C - Clear Channel Configuration

TYPE

Channel

EXECUTION

Deferred

SYNTAX

*C

Clear out the channel configuration so that no channels are configured

DESCRIPTION

The Clear Channel Configuration (*C) command will clear out the channel configuration so that no channels are

configured. After this command has been performed, channel readings will be not be updated; therefore, no HLL

or acquisition buffer updates will be performed until a new configuration is entered via the Configure Channels (C)

command. This command may be used when the present configuration is no longer ac ceptable and you wish to

reconfigure channels from scratch.

EXAMPLE

PRINT#1,"*CX"

‘ Clear all channels configuration

PRINT#1,"C1, 1X"

‘ Configure channel 1 of T/C type J

*F - Restore Factory Settings

TYPE

System

EXECUTION

Immediate

SYNTAX

*F

Restore unit to factory configuration

DESCRIPTION

The Restore Factory Defaults (*F) command may be used to restore the unit to the s ame configuration it had

when it left the factory. Issuing this command will cause the unit to load the factory default configuration into the

working configuration. The factory default configuration is defined in the Configuring Power-Up S t ate section of

Appendix D.

This command may not be issued while an acquisition is configured since it will cause certain settings upon

which the acquisition depends to change. Issuing this command while an acquisition is configured will cause a

Conflict Error to occur.

Note: Issuing the *F command will cause any previously defined configuration to be irrevocably lost. The

calibration factors, however, will remain intact.

EXAMPLE
