Blue Button
Document Actions
The blue button has two functions:
-
First - The blue capacitor symbol to the right of the Omega Ω symbol indicates that capacitance can be measured if the blue button is pressed. Capacitance measurements are limited to 0.01 nF to 5.0 µF, not very useful in automotive applications.
- Second - When measuring current, by default, DC amperage measurements are enabled. To enable AC amperage measurements, press the blue button.
Note: This button on the Fluke 87-V is yellow in color.
