ADDRESS value
Sets the multimeter's GPIB address (from the 
front panel only). The address is stored in 
continuous memory and is not lost when power is 
removed.
value: The value parameter is an integer from 0 to 
31.
Power-on value = previously stored address 
(factory setting = 22).
Default value = none: parameter required.
APER [aperture]
Aperture. Specifies the A/D converter integration 
time in seconds.
aperture: Specifies the A/D converter's 
integration time and overrides any previously 
specified integration time or resolution. The valid 
range for aperture is 0 - 1s in increments of 100 
ns. (Specifying a value <500 ns selects minimum 
aperture which is 500 ns.)
Power-on aperture = is determined by the 
power-on value for NPLC which specifies an 
integration time of 166.667 ms for a 60 Hz power 
line frequency, or 200 ms for a power line 
frequency of 50 Hz or 40O Hz.
Default aperture = 5OO ns.
