•
If a message window opens, follow the instruction in the message to change the setting value.
•
The Scaling function performs calculation using a ratio of the Meas. Value and EU Output Value settings.
The digital display shows "++++/----" when the converted value cannot be processed by the GL840.
•
The span may be changed depending on the Scaling settings.
•
For temperature input, the offset setting for an input value is used.
Setting example: For voltage input
Meas. Value
Upper limit +5.000
Lower limit
-5.000
+5 V
CH.1 10V
-5 V

Sets the scaling function to ON or OFF.
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.
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.
Sets the decimal point position for an EU output value.
Selects a specific engineering unit classification. (The following are available.)
Current, length, area, volume, speed, acceleration, frequency, weight, work, pressure, flow
rate, temperature
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."
Sets a unit to be used after conversion.
Arbitrary text consisting of alphabetical characters and numerical values can be set as a unit.
(For the character input, refer to "(9) Character string input" in "3.4 Setting Menus".)
When "Select Unit" or "Unit" is specified, it is reflected in here.
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.
