Reading the registers
You can read any register in the Status Model. The response is a decimal value that indicates which
bits in the register are set. See Register bit descriptions (on page D-9) for information on how to
convert the decimal value to bits.
You can use the query commands in the STATus subsystem (on page 7-94) or send common
commands to read registers. For example, you can send the following command to read the Status
Enable Register of the Standard Event Register:
*ese?
Clearing the registers
Registers in the status model can be cleared using commands or by instrument actions. When a
registered is cleared, the bits in the register are set to 0.
The event log and all registers are cleared when instrument power is cycled.
Send the command *CLS to clear the following event registers and error queue:
Standard Event Register
Operation Event Register
Operation Instrument Event Register
Operation Instrument Summary Event Register
Questionable Event Register
Questionable Instrument Event Register
Questionable Instrument Summary Event Register
Measurement Event Register
Measurement Instrument Event Register
Measurement Instrument Summary Event Register
Status Byte register
Error queue
In addition to this command, any enable register can be reset by sending the 0 parameter value with
the individual command to program the register.
