Integration Time (Bandwidth, Gate Time)
Four measurement functions
allow you to select the integration time: dc voltage, dc current, resistance,
and temperature. The ac voltage and current measurements allow you to
select the ac signal filter (bandwidth). The frequency/period function
allows you to select gate time. The navigation keypad provides a shortcut
for quickly changing these settings.
•
If the multimeter is configured to take the measurement using an
integration time in
NPLCs
, pressing
or
during front panel
measurement operations will increase or decrease the integration time
setting, and briefly display the new setting on the second display line
(e.g. if the setting was
0.2 NPLC
, the display will show

when you
press
). Repeated use of
or

NPLC
).
