5.4 Advanced Settings for Each Channel
98
This section describes configuring settings such as the display color, number of
display digits, and scaling for each channel on the display settings page of the
channel settings.
In the case of the 8948 Voltage/Temp Unit and 8949 Universal Unit:
Use of the scaling function enables converting the output voltage obtained from,
for instance, a sensor to the physical quantity of the measurement object in order
to perform measurement. The gauge graduations, scale (vertical axis upper limit
value and lower limit value) values, and A-B cursor measurement values can be
displayed as scaled values and units. The following two types of scaling meth-
ods are available.
•
Setting by ratio
Set the physical quantity per 1 V input
signal (ratio eu/V), offset value, and
unit name for conversion (eu: engi-
neering unit), and convert the mea-
surement values obtained as voltage
values to values of the set unit.
Example
Ratio: Value of A/V
Offset Value: B
Unit name: A
•
Setting by 2 points
Set the voltage values at 2 points
of the input signal, the conversion
value of those 2 points, and the
unit name for conversion, and con-
vert the measurement values
obtained as voltage values to val-
ues of the set unit.
Example
Unit values for conversion of volt-
age values at 2 points
V
H
: High voltage point
A
H
: Conversion value for the high
voltage point
V
L
: Low voltage point
A
L
: Conversion value for the low voltage point
Unit name: A
