Due to customer feedback LabDevice improved their current probes. They feature now a green led which is indicating that the USB power is connected.
Further the CMRR of the device got improved. This allows even more accurate measurements at high frequencies.
New video online.:
There is a new video which shows how to measure the PWM currents of a dimmed LED. The PWM signal which is used for dimming the LED has a very high base frequency ~60kHz. Current measurements with the LabDevice low cost current probes are no problem even with this high frequency.
Other possible applications for the LabDevice current probes:
LabDevice launched their first two products:
Have you ever ask yourself how to measure and display current instead of voltage with an oscilloscope? LabDevice developed an easy to use active current probe which is able to plot a current profile on an oscilloscope. Two types of current probes with different measurement ranges are available:
The current probes measure with the following key features:
It can be used in many different measurement situation.
