# Scaling Voltage Inputs

Scaling to engineering units will depend on the application (water tank level, etc.). Use Alarmware™ to configure your channel settings by first connecting with the Catalyst unit. From the "Configuration" menu, select "Channels." To read a voltage input directly in volts, do the following:

Step #1. First enter the SNA for the Analog Input:

- 1*1*30001

Step 1

Select the “2-Point Scaling” option.

Step 2

Enter the following scaling data:

- X1 = 0 Y1 = 0
- X2 = 8191 Y2 = 10
