How to display numerical data
values? Press WAVE/DATA repeatedly to cycle
through the Waveform (only), Waveform
+ Numerical Values, and Numerical Val-
ues (only) displays.
Numerical values can be displayed in a
large font on the enlarged numerical dis-
play.
Numerical values at specific locations
can be displayed using A/B cursors.

Screens" (p .21)
"Viewing Input Signals
as Numerical Values"
(p .89)

ues" (p .93)
What happens to pulse integra-
tion 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 In-
stantaneous ( [Inst] ), and summing later
with a spreadsheet program.
"Integration (Count)
Measurement Set-
tings" (p .64)
What is the timing difference be-
tween CH1 and CH2? When the [Filter] is Off, the time differ-
ence between data on neighboring
channels is about 500
μ
s, regardless of
recording interval. When the [Filter] is
enabled (50 or 60 Hz), the time differ-
ence increases with longer recording in-
tervals.

ing" (p. A1)
How can I apply markers while
measuring for easy searching lat-
er? How can I search for alarm
event locations? Event marks can be applied by the fol-
lowing methods.
• Press
START while measuring
• Press the on-screen [Make Mark]
button.
• Apply a signal to the EXT.TRIG termi-
nal
• When a warning occurs
"4.3 Marking Wave-
forms and Searching
Marks (Search Func-
tion)" (p. 95)
Multiple temperature measure-
ment values are scattered, even at
the same location. Is it possible to
match the value measured on
CH1? The Offset Cancel function is conve-
nient for this.
The value measured on UNIT1, CH1 is
used as the scaling (offset) value for
other channels. "3.6 Scaling Settings
(as needed)" (p. 71)
Is it possible to signal an alarm on
ALM1 when the temperature on
CH1 exceeds 40
°
C, and on ALM2
when it exceeds 50
°
C?
Yes. Four alarm channels are provided.
Multiple alarms can be assigned to the
same input channel. "5.2 Alarm Output" (p.
111)
