How can I acquire data contin-
uously starting on April 1,
2015, daily from 9:00 to 17:00,
for one month? Set as follows:

Is it possible to measure on 20
channels using two instru-
ments synchronized with each
other? Measurement start can be synchro-
nized with each others using an ex-
ternal trigger. Sampling cannot be
synchronized with them. “9.5 Synchronous
Measurements with
Multiple Instruments”
(p.163)

What should I do about zero
offset when the input is short-
ed? Execute zero adjustment to com-
pensate for offset when the inputs
are shorted. “2.5 Zero Adjust-
ment” (p.41)
Even though a signal is only in-
put on CH1, why do similar
waveforms appear on unused
channels? An open-circuit input terminal can be
affected by signals on other chan-
nels. By closing the input terminal
circuit, normal measurement is pos-
sible. If this is impractical, disable
unused measurement channels, or
short the + and - terminals together.
How to display numerical data
values? Press WAVE/DATA repeatedly to
cycle through the Waveform (only),
Wa Numerical Values, and
Numerical Values (only) displays.
Numerical values can be displayed
in a large font on the enlarged nu-
merical display.
Numerical values at specific loca-
tions can be displayed using A/B
cursors.

rations” (p.20)

Values” (p.101)

nals as Numerical
Values” (p.104)
What happens to pulse inte-
gration when there are more
than one million pulses? The counter saturates at
1,073,741,823 counts. If you expect
to exceed this count, we recommend
measuring with the Integration Mode
(
[Count]
) set to Instantaneous
( [Inst] ), and summing later with a
spreadsheet program.

tings” (p.63)
