Partially Expanded Recording (PARTIAL)
This setting specifies whether to carry out partially expanded recording, and if so, which
percentage of the recording span will be compressed and the corresponding boundary
value.
If the instrument is equipped with the optional computation function or floppydisk drive,
this setting can also be made for computation channels A01 to A60.
Selecting Partial Recording ON/OFF
ON: Partial recording will be carried out;
OFF: Partial recording will not be carried out.
Specifying the Compressed Part and Boundary Value
• RATE : This setting specifies which percentage (1 to 99%) of the full recording span
will be compressed. The default value is 50%.
• Boundary value: This setting specifies the boundary value which corresponds to the
previous set compressed part. The setting lies within the recording span, but when
linear scaling is being used, the setting lies within the left/right scale range. The
default value is 0.
Note
If boundary values are to be set for succeeding channels, the decimal point is handled as
below.
If succeeding channels are set, the decimal point position of boundary values when the
measurement range for each channel setting is different, is that determined for each
corresponding range. As a result, it exceeds the measurable range, an error occurs.
For example, if channels whose measurement ranges are 20 mV, 2 V, and type T thermocouple
are set and the boundary value is set to 10000, the following applies:
The boundary value of the channel whose measurement range is 20 mV: 10.000 mV;
The boundary value of the channel whose measurement range is 2 V: 1.0000 V; and
The boundary value of the channel whose measurement range is type T thermocouple:
1000.0 °C
As the range of type T thermocouple is –200.0 to 400.0 °C, an error occurs for this channel.
Notes on Partially Expanded Recording
• Partial recording cannot be carried out if the input type of the computation channels is
SKIP or DI or if the computation channels are OFF.
• Partially expanded settings will be automatically canceled when either of the following
changes occur.
• the input type has been changed;
• the measurement range has been changed;
• the recording span has been changed;
• linear scaling settings have been changed;
• the reference channel for difference between channels has been changed.
Interpolation (INTERPOL)
This setting can be set for each channel individually. If the instrument is equipped with
the optional computation function or floppydisk drive, this setting can also be made for
computation channels A01 to A60. The default setting is OFF.
OFF: no interpolation will be carried out.
ON: interpolation will be carried out according to the priority of recording colors. The
priority of recording colors is black > purple > reddish purple > navy blue > red > blue >
brown > green > orange > yellowish green.
