Advanced Scaling

The Layer N SS-015 allows for advanced scaling options on process and pulse inputs only. The

Advanced Scaling

checkbox can be selected to expand additional configuration options. A gain and/or offset can be applied to the

input reading and the displayed unit can be changed.

To apply a gain or offset to the input, expand the

Scaling

menu and ensure that

Apply Scaling

is checked. There,

the gain and offset values can be adjusted. Both positive and negative values may be entered as well as decimal

numbers. The equation for the scaled input value is given below.

The displayed units can be changed by entering a new value in the

Unit

field and clicking

Apply Settings

. This

field is limited to a maximum of 4 characters. Note that changing the Unit field does not change the base unit

type, only the display name. The

Lock

checkbox must be selected to use the user-defined Unit field. Unchecking

the Lock checkbox and clicking Apply Settings will revert the unit display back to the default setting.

The screenshot above shows an example application for advanced scaling with renamed units. A fan

tachometer with a 500 Hz signal is connected to the Pulse Rate input. The fan outputs 2 pulses per revolution,

so to convert to rotations per minute (RPM) the reading must be divided by 2 which is accomplished by setting

the Gain to 0.5. The units can then be renamed to RPM and will display as such.
