(1)-11 EU (Scaling settings)
This is used to convert the measured signals to other units. This setting is available only if Pulse is selected in (1)-7.
Setting
(1) EU Function
(2) Meas. Value
(3) EU Output Value
(4) Select
(5) Unit
(6) Arbitrary Unit
•
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 varied depending on the scaling settings.

Sets the scaling function to ON or OFF.
Sets a value to be converted.
Sets an output value after conversion.
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.
When "Select" or "Unit" is used, the setting is reflected in this field.

When setting the pulse input to the number of revolutions, set the number of pulses per
revolution.
As the number of pulses per revolution set here is 1 revolution, the number of revolutions per
minute (RPM) is calculated.calculated. For example, if "100" is set, 1 rotation is judged when
100 pulses have been input.
<Calculation formula>
Number of revolutions (RPM) = Pulse input frequency ÷ Number of pulses per revolution x
60 (1 minute)
<Example>
Number of pulses per revolution: 100 (1 rotation is judged when 100 pulses have been input.)
Pulse input: 1000 Hz (1000 pulses per sec.)
Number of revolutions: 600 RPM (600 RPM per min.)
