Programming And Reading Registers - Keithley 2601 Reference Manual

Series 2600 System SourceMeter® Instruments Reference Manual
Commands to reset the status registers and the Error Queue are listed in
these commands, any programmable register can be reset by sending the 0 parameter value with
the individual command to program the register.
Table D-2
Commands to reset registers and clear queues
Commands
To Reset Registers:
*CLS
status.reset()
To Clear Error Queue:
errorqueue.clear()
The instrument automatically clears the ouput queue when the instrument transitions from the
local control state to the remote control state.

Programming and reading registers

Programming enable and transition registers
The only registers that can be programmed by the user are the enable and paragraphs transition
registers. All other registers in the status structure are read-only registers. The following explain
how to determine the parameter values for the various commands used to program enable
registers. The actual commands are summarized in
A command to program an event enable or transition register is sent with a parameter value that
determines the desired state (0 or 1) of each bit in the appropriate register. The bit positions of the
register
of the registers, send the decimal value for the bit(s) to be set. The registers are discussed further
in "Enable and transition registers"
program these registers are outlined later in this appendix.
