*CLS — Clear Status Clear status registers and error queue
Description
Use the *CLS command to clear (reset to 0) the bits of the following registers in the Model
2000:
• Standard Event Register
• Operation Even Register
• Error Queue
• Measurement Event Register
• Questionable Event Register
This command also forces the instrument into the operation complete command idle state and
operation complete query idle state.
*ESE <NRf> — Event Enable Program the standard event enable register
*ESE? — Event Enable Query Read the standard event register
Parameters
<NRf> = 0 Clear register
1 Set OPC (B0)
4 Set QYE (B2)
8 Set DDE (B3)
16 Set EXE (B4)
32 Set CME (B5)
64 Set URQ (B6)
128 Set PON (B7)
255 Set all bits
Description
Use the *ESE command to program the Standard Event Enable Register. This command is
sent with the decimal equivalent of the binary value that determines the desired state (0 or 1) of
the bits in the register. This register is cleared on power-up.
This register is used as a mask for the Standard Event Register. When a standard event is
masked, the occurrence of that event will not set the Event Summary Bit (ESB) in the Status
Byte Register. Conversely, when a standard event is unmasked (enabled), the occurrence of that
event sets the ESB bit. For information on the Standard Event Register and descriptions of the
standard event bits see the next section.
A cleared bit (0) in the enabled register prevents (masks) the ESB bit in the Status Byte Reg-
ister from setting when the corresponding standard event occurs. A set bit (1) in the enable reg-
ister allows (enables) the ESB bit to set when the corresponding standard event occurs.
