Integration Time
(continued)
• Front-Panel Operation: Integration time is set indirectly when you
select the number of digits. See the table for resolution on page 54.
• Remote Interface Operation:
< function >:NPLCycles {0.02|0.2|1|10|100|MINimum|MAXimum}
For frequency and period measurements, aperture time (or gate time)
is analogous to integration time. Specify 10 ms (4
1 ⁄
2
digits), 100 ms
(default; 5 1 ⁄
2
digits), or 1 second (6 1 ⁄
2
digits).
FREQuency:APERture {0.01|0.1|1|MINimum|MAXimum}
PERiod:APERture {0.01|0.1|1|MINimum|MAXimum}
Front / Rear Input Terminal Switching
Any measurement made using the front terminals can also be made
using the input terminals on the rear panel. See “The Front Panel at
a Glance,” on page 2, for the location of the front / rear switch.
The input terminals can only be configured from the front panel.
You cannot select the terminals from the remote interface, but you
can query the present setting.
• The Rear annunciator turns on when you select the rear terminals.
• Remote Interface Operation: You can query the multimeter to
determine whether the front or rear input terminals are selected.
ROUTe:TERMinals? returns “ FRON ” or “ REAR ”
