Remarks
Caution
168 Chapter 6 Command Reference
Refer to the FUNC command.
Enables or disables the multimeter's input protection algorithm (see CAUTION
below) and some syntax and error checking algorithms. With these algorithms
disabled, the multimeter can change to a new measurement configuration faster
than it can with them enabled.
DEFEAT [mode]
The mode parameter choices are:
Numeric
mode Query
Parameter Equiv.
OFF 0
ON 1
Power-on mode = OFF
Default mode = OFF.
DEFEAT ON must only be used when you are certain that
overload voltages on the Input terminals will not exceed ±100V
peak on the 10V range or below. (On the 100V and 1000V
ranges, the multimeter can withstand voltages up to ±1200V
peak regardless of whether DEFEAT is ON or OFF.) DEFEAT ON
disables (defeats) the input switch sequencing that protects the
multimeter's input circuitry from overload voltages. If input
protection is disabled and an overload situation is detected on
the 10V range or below, the multimeter will enable input
protection and internally tally the overload for instrument
warranty considerations.
•
Since DEFEAT ON disables certain syntax checking and error reporting
algorithms, it should be used only after all system programming is complete and
operational.
•
Query Command The DEFEAT? query command returns the present
DEFEAT mode. Refer to "Query Commands" near the front of this chapter for
more information.
