Configuring the DX100/DX200/DX200C/MV100/MV200
8.2 Setting the Measurement Channels
Input Type (Mode and Range/Type)
Select from the list of choices from the pull-down menu.
Mode Relevant Settings
VOLT (voltage) Range, span L, and span U
TC (thermocouple) Type, span L, and span U
RTD (resistance temperature detector) Type, span L, and span U
DI (voltage level/contact input)
Range, span L, and span U
SKIP (Measurement/Display OFF) None
Note
• When a value outside the range is entered or when the span L and span U values are set to
the same value, they are corrected when the data are checked.
• If SKIP is selected, settings such as Delta/Scale/Sqrt and Range/Type are discarded.
Difference Computation and Reference
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.
Display Span
Sets the upper and lower limits (full scale) of the display.
When the span L and span U values are set to the same value or when a value outside
the range is entered, they are corrected when the data are checked.
Scale
Scale L, scale U, and decimal point
Scale’s value is displayed by taking the range between scale L and scale U to be full
scale. Enter the upper and lower limit values to which you wish to convert the raw
values. Include the decimal point.
When the scale L and scale U values are set to the same value or when a value outside
the range is entered, they are corrected when the data are checked.
Unit
Enter the unit using up to six characters.
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.
