Setting the Span
The measurement range is decided according to the type of input. The left and right
span must lie within the measurement range. However, the span is 0 to 1 for the DI input
type.
For the remote RJC, the setting range for span is the same as that for the reference
channel.
Click the “Range Information” tab on the single channel specific setting screen, to refer
the type of input and the measurable range.
Selecting the Input Type for Linear Scaling
The input type can be selected from the following.
• VOLT (DC voltage)
• TC (thermocouple)
• RTD (resistance temperature detector)
• DI (contact)
• mA (DC current)
• AC (Power Monitor
• STRAIN
• PULSE (For pulse, scaling setting is insufficient)
Setting Linear Scaling Values (SCL)
The left scaling and right scaling values are set following the left and right span values of
the span menu. The value on the left side of the SCL menu shows the left scaling value,
and the value on the right side of the SCL menu shows the right scaling value. The
setting ranges from -30000 to 30000.
• Set the number of digits to the right the decimal to four digits or less.
• The default settings are 0.00 for the left span and 100.00 for the right span.
Setting the power monitor channel number
This procedure sets the channel number for which you want to show and record the
values of a parameter selected from the effective voltage, effective current, active power,
reactive power, apparent power, frequency, power factor and phase angle which were
calculated using the measured data. Therefore, it does not correlate with the terminals
of an input module.
Setting power monitor parameters
A power monitor module measures the voltage or current through the respective
channels. The values that are shown and saved are not those of the voltage and current
being actually measured through each channel but the values of the parameters you set
here.
A combination of parameters being measured is fixed for each group of channels 1-2,
3-4 and 5-6 within the same module. For example, setting channel 1 to P1 (active power
1) sets channel 2 to VA1 (apparent power 1). In addition, the configurable parameters
being measured varies depending on the wiring method selected.
Setting the Span for the power monitor
Set the left and right spans within the limits of the measuring range specified by the “Input
Range.” In the SPAN menu item, the left-hand value is the left span and the right-hand
value the right span.
