to give the most accurate results. See examples below.
Example 1: If you are measuring battery voltage, we want the NetGuardian to show that the input is -54.2 VDC if -
54.2 VDC is really being measured. However, if you are measuring temperature, the values are typically not a 1 : 1
ratio.
Example 2: Your X-Type sensor outputs 4 - 20mA. (We use a 250 ohm resistor to convert current to voltage
measurement. Ohms Law tells us that 4mA x 250 ohms = 5 VDC. The sensor should tell us what the output current
references. In this example, 4mA = 23º F and 20mA = 131º F
OR
1V = 23º F and 5V = 131º F.
