Although RESET can be used from remote, it is intended primarily for front
panel use. RESET configures the multimeter to a good starting point for local
operation. Executing the RESET command from the alphabetic menu resets the
multimeter as shown above. Pressing the shifted front panel Reset key, however,
has the same effect as cycling the multimeter's power. This stores the present
state as state 0, any compressed subprograms are destroyed, stored readings are
destroyed, the power-on SRQ bit is set in the status register, and the power-on
sequence is performed.
•
When attempting to send the RESET command from remote, it is possible that
the multimeter is busy or the GPIB bus is being held. In either case, the
multimeter will not respond immediately to the remote RESET command. For
this reason, you should send the GPIB device clear command before you send
the multimeter's RESET command. This is shown in the example below.
