Is it possible to measure on 20
channels using two synchro-
nized HiLoggers? Measurement start can be synchro-
nized using an external trigger.
Sampling cannot be synchronized. 9.5, "Synchronous
Measurements with
Multiple Instruments"
(p.135)

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.35)
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.

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.
