(2) Measurement Functions
∗
1: Settable for up to 15 channels (U1-1 to -15) when thermocouple burn-out is disabled.
∗
2: Settable for up to 30 channels (up to U2-1 to U2-15) when thermocouple burn-out disabled, or up
to 15 channels (U1-1 to U1-15) when enabled.
∗
3: Settable for up to 60 channels (up to U3-1 to -15 and U4-1 to -15) when thermocouple burn-out
is disabled, or up to 30 channels (U2-1 to -15) when enabled.

Recording length (time
span) Set continuous recording Off or On.
When Off, any time can be set.
Repeating Measure-
ment Recording Set Off or On.
When On, measurement repeats at the set recording interval.
Recording Data Quantity Analog recording n channels: 8 M/n data values
Waveform storage The most recent 8 million data values (one analog channel recording
time, or 8 M / n values for n channels) are stored in internal memory (n =
number of analog ch pulse channels × 2 + digital channels × 1 +
alarm channels × 5 words)
Data retained in memory can be observed by backward scrolling.
Measurement data
backup Data is retained for about 30 minutes after power-off
(except when powered off while writing to removable storage, or within
five minutes after power-on)

• When selecting by position, magnification can be × 100, × 50, × 20, ×
10, × 5, × 2, × 1, or × 1/2. 0 Position: Set between -50% and 150%
(at 1X magnification)
• When selected by upper/lower limits, specify the limit values.
Waveform scrolling Time-axis scrolling is available by left/right arrow keys while measuring
and when measurement stops (waveform drawing period).
These keys make large jumps
Jump function Selects the displayed span of the waveform.
Monitor function Confirm instantaneous values and waveforms without recording data.
(Monitoring is performed while triggering.)
