(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) w
hen 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 channels + 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)

Vertical axis (voltage
axis)
Select by position or upper/lower limits
• 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.
