Polarity Quick Tip

“Be Positive!  Negativity doesn’t get you anywhere.” – Peter W. Murphy

First in the series of Fall Quick tips:   Polarity

If Input 1 is more Negative than Input 2, there will be an Upward deflection.

Opposite of what you might think of Positive and Negative…the Reverse is True.

Quick Examples:

• If input 1 is 3 mV and input 2 is 5 mV – the deflection will be Upward.
• If input 1 is 8 mV and input 2 is 5 mV – the deflection will be Downward.
• If input 1 is 50 mV and input 2 is 80 mV – the deflection will be Upward.
• If input 1 is 30 mV and input 2 is 30 mV – the deflection will be Canceled Out.

Just Remember:

The Deflection = Input 1 – Input 2

and

An upward deflection is surface negative, and a downward deflection is surface positive.
