Analog Polarity Override

iF : integrated temperature sensor in fahrenheit or iC for celsius
oV+ : override polarity VDC to positive
oV- : override polarity VDC to negative
If you have a positive powered NetGuardian, you may want to use this feature if you are using the
internal battery sensor. The Web Browser Interface will override oV+ and oV- tags and show VDC. So
you won't have to view an uncommon looking tag while in monitor mode.
Analog Accuracy:
+/- 1% of analog range.

Analog Delta

Sometimes, simply checking the alarm threshold values of your analog sensors is not enough. The
Analog Delta feature allows you to define a discrete alarm to be triggered when your analog value
changes too quickly, even if it does not reach an alarm threshold. For example, if temperature or
pressure begins rapidly changing, which can cause damage to sensitive equipment.
In the Edit > Analog Delta menu, you can define a time period and maximum acceptable delta that will
let your NetGuardian know how quickly a value is allowed to change, and how often to check for a
change.
