Linear Scaling (SCALE)
Converts the unit to obtain the measured value.
• Scale L, Scale U
Input range after converting the unit. The selectable range is from –30000 to 30000.
• Point
Set the number of digits to the right the decimal to four digits or less.
Note
• The FX converts the measured value to a value obtained by removing the decimal point
from the value span specified by [Scale L] and [Scale U]. For example, if the scale setting is
“–5 to 5,” the value is converted to a value within the span of “10”; if the scale setting is “–5.0
to 5.0,” the value is converted to a value within a span of “100.” In this case, the resolution
of the value converted to a span of “10” is lower than the value converted to a span of “100.”
To prevent the display from becoming rough, it is recommended that the scale be set so that
this value is greater than 100.
• You cannot set the same value to [Scale L and [Scale U].
• When the [Mode] is [1-5V] or [Sqrt], [Scale L] must be less than [Scale U].
Difference Computation (DELTA)
Displays the difference between the input and the reference channel.
If difference computation is performed between channels that have different range and
type settings, the decimal position of the computed result is set to that of the channel
computing the difference. If the number of digits to the right of the decimal of the
reference channel is greater than that of the channel computing the difference, the
reference value below the least significant digit of the channel computing difference is
rounded beforehand.
Ref. CH
The reference channel for difference computation.
Note
If you set the reference channel of a differential computation between channels to a channel
that is set to [LogType1] or [LogType2], an error will be returned as the measured result of the
differential computation between channels.
Square Root
Computes and displays the square root of the input. This setting can be used only when
the input mode is set to VOLT (voltage). As necessary, set the span, scale, and unit. You
can only configure the settings such that [Scale_L] is less than [Scale_U].
Unit
Enter the unit using up to six characters.
