The emergency switch off
This is not the correct method of switching off the instrument. Using it can cause data corruption. Use this
method only in cases when it is absolutely necessary.
Push and hold the POWER button for about 5 seconds, then release the button. The instrument will switch off.
Memory capacity warning
If the memory capacity warning appears (see the picture below), you need to free up some memory space by
removing some measurements or routes.
Connection to the computer
Use the mini-USB cable, which is the standard accessory of the VA3Pro set, to connect the device to the
computer. There is a mini-USB port on the top side of the VA3 device for the connection.
The VA3Pro unit should be switched off or on the main menu screen.
When the VA3 is connected, the new device (new flash drive) appears on the computer. The name is
VA3_DISC. If this operation fails, switch off the unit and try to connect it again.
Always use the Safely remove hardware function before disconnecting the VA3Pro unit from the PC!
The va3 folder (case sensitive) is automatically created on VA3_DISC.
The DSP board
The DSP board is the most important part of the instrument. The special chip carries out all necessary
operations which are required for achieving 3 channel synchronous data measurement.
The DSP status LED is the right hand LED on the top right corner and allows the operator to monitor the DSP
board. Several states can appear:
- Flashing green with 0.25 sec time interval (4Hz, four times per sec) - the measurement is running.
- Flashing green with 1 sec time interval - STANDBY, the measurement is not running.
- Red - the DSP board is not working properly.
