"Excellent Product / Support"

My company is still in it's honeymoon period with our smart whiteboard but so far it is great. Customer/tech support is outstanding. I have called many times and have always received above average assistance.

"I'm so pleased with my OneScreen!!"

I'm so pleased with my OneScreen! In addition to all the wonderful features (up to 10 or so people writing simultaneously, seamlessly transitioning from the white board feature to the internet, moving specific parts of what you write on a whim, etc.), the support is phenomenal!

"Great enhancement for our administration."

The board has worked very well for our application and operations. Support has been very quick to respond when questions have come up.

"How to identify the components in the circuit"

1. Online power-on test
Mainly based on its model or working state to determine the voltage across the pin, such as diodes and rectifier bridges have a tube voltage drop, and the triode should judge the emitter junction voltage or collector voltage according to its working state.
2, offline measurement
in the case of power failure, remove the components, measure the unidirectional conduction characteristics of the diode and rectifier bridge, and measure the quality of the triode with the basic amplifier circuit of the triode.
