CHAPTER 3 Settings and Measurement
(1)-4 EU (Scaling settings)
Converts the measured signals to other units.
<For voltage input> <For temperature input>
Setting Description
(1) EU Function Sets the scaling function to ON or OFF.
(2) Meas. Value (Upper/
Lower)
Sets the upper and lower limits of values to be converted.
* For temperature input, there is no distinction between upper and lower limits.
* See the setting examples shown below for details.
(3) EU Output Value (Up-
per/Lower)
Sets the upper/lower limit output values after conversion.
* For temperature input, there is no distinction between upper and lower limits.
* See the setting examples shown below for details.
(4) Dec pt Sets the decimal point position for an EU output value.
(5) Select Selects a specific engineering unit classification. (The following are available.)
Current,length,area,volume,speed,acceleration,frequency,weight,work,pres-
sure, flow rate, temperature
(6) Choose Selects a unit to be used after conversion. A unit displayed in this field belongs to
the classification selected in "Select."To set a unit not displayed in this field, set
arbitrary text in "Arbitrary unit." The setting selected in this field is displayed in
"Arbitrary unit."
(7) Arbitrary Unit Sets a unit to be used after conversion. Arbitrary text consisting of alphabetical
characters and numerical values can be set as a unit. (Refer to page 3-46 for de-
tails on the text input.)When "Select" or "Choose" is used, the setting is reflected
in this field.
(8) Reads the current
temperature measurement
value
Substitutes the current measurement value into (2) Measurement value and (3)
EU output value.
* The value is not substituted when burnout occurs or the scale is exceeded.
