Function Description
■ High / Low-limit scale value
This function is to display setting of particular high / low-limit value in order to display high /
low-limit value of measured input.
If measured inputs are a and b and particular values are A and B, it will display a = A, b = B as
below graphs.
• When changing input range, it is changed automatically as factory default display range of
the input range.

■ High / low-limit value of transmission output and
High / low-limit scale value of transmission output
This function is to set output scale and range for display value for transmission output.

A: High-limit value of transmission output 1 / 2
B: Low-limit value of transmission output 1 / 2
C: Low-limit scale value of transmission output 1 / 2
D: High-limit scale value of transmission output 1 / 2
When the input value set at low-limit scale value of transmission output 1 / 2 is displayed, the
output value set at low-limit value of transmission output 1 / 2 is transmitted.
When the input value set at high-limit scale value of transmission output 1 / 2 is displayed, the
output value set at high-limit value of transmission output 1 / 2 is transnitted.
• E.g: Relation among input type, high / low-limit input value, high / low-limit scale, high / low-
limit scale value of transmission output 1 / 2, and high / low-limit value of transmission
output 1 / 2. The below figure is the example for 4 to 20mA input.

■ Input correction
This function is to correct the error occurring from a thermocouple, a RTD or analog input
out of allowable error range of this unit.
This is also available to correct error when a sensor cannot contact the subject position by
calculating the error temperature.
When executing input correction function, you should measure the error from a sensor
accurately. If the measured error is not correct, error may be greater.
• E.g.: When measured temperature is 4 ℃ and actual temperature is 0 ℃. Set IN-B as -4, and
and display value is 0 ℃.
■ Normal / moving average digital filter
Digital filter is able to stably display and output the noise from input line and irregular signals.
Normal average filter displays the averaged n times of input values periodically. Moving
average filter displays the moving averaged n times of input values in real time.

■ Atmospheric pressure (0) setting for Two Unit Function
When connecting a pressure sensor, compound pressure which is below atmospheric
pressure (0) is for vacuum as mmHg and which is atmospheric pressure or over it is for
positive pressure as kg/cm
display 0 kg/cm
, you can correct zero-point adjustment function.

When using two unit function, low-limit scale is fixed as -760. low-limit scale parameter is
displayed but you cannot set this. You can set high-limit scale within 0 to 9999 range.
• E.g: When pressure range is -760.0 mmHg to 3.000 kg/cm
DC 4 - 20 mA and it outputs 8.00 mA for atmospheric pressure (0), set input special
function = TUF, high-limit scale = 3000, decimal point position = 0.000, atmospheric
pressure = 08.00. This unit displays for 4 mA input as -760, for 8 mA input as 0.000 and 20
mA input as 3.000.
