Electronic measuring modules
with USB connection.
- This site is about
the measuring instruments for measuring electrical quantities using the PC monitor
to display that.
- Measuring devices
are small modules, which are connected to PC using a USB cable.
Advantages of such solutions is that the module is not using display
and also the module does not
need power supplies - power is the USB connector of
computer. Therefore, the modules have small dimensions and
are fully operational.
- Using the module is
commonly measured values for amateurs and professionals.
It can be extended to the new features in the software and the
hardware.The modules are electrically connected directly with the
PC.
- Connection
with computers
have 2 benefits : there is no
need for display
and frequency counter also does
not need an power supply - needed
current takes from PC (via USB). It works well also with the
notebook.
- usb voltmeter
- usb frequency counter
- usb LC meter
- usb ampermeter- The
modules are electrically
connected directly with
the PC.
- Using of the
modules is simple.First, it is necessary to attach the module to the PC
and install the usb
drivers and program. Then the module is ready for use.
Software and usb drivers are free.
For developers is provided the COM
component which allows you to make own application for all
offered modules. Also on the page is the source code and examples of
its use.
The
parameters of the modules:
- usb voltmeter : range 0 - 50 V , input impedance > 2 MOhm
- usb frequency counter : range 0 - 50 MHz ,input impedance > 1
MOhm
- usb LC meter C : 1pF - 2 mF, H : 1 nH - 1 mH
- usb ampermeter : range 0 - 1 A ,
