Resetting the
Multimeter
During operation, programming errors and other conditions may occur
making it necessary to reset the multimeter. This section shows you how to
reset and clear the multimeter, and read its error queue.
The multimeter is reset with the command:
*RST
which can be sent from an HP 9000 Series 200/300 computer as:
OUTPUT 70903;"*RST"
The multimeter can also be reset by pressing the green “Reset Instr” key on
the HP E1301A mainframe front panel. Note that the multimeter must first
be selected from the mainframe menu.
When resetting the multimeter:
• A front panel reset (“Reset Instr” key on the HP E1301A mainframe)
returns the multimeter to the idle state from the busy state and sets the
multimeter’s power-on configuration (Table 1-3). A front panel reset is
equivalent to clearing the multimeter followed by a reset.
• A reset from the computer (*RST) returns the multimeter to the idle
state from the busy state if the multimeter is busy due to a command
entered from the front panel. If the multimeter is busy due to a
command sent from the computer, you must clear the multimeter
before sending the reset. The reset sets the multimeter’s power-on
configuration.
