Needle Calibration Test allows you to verify the calibration of the
eTRAX™ and VirtuTRAX™ devices. The values obtained have to be as
close as possible to 0. If it is not the case, redo the calibration and make
sure that the device is within the electro-magnetic field and that there is
no magnetic objects close to either the transmitter or the sensor of the
device.
"(
If after redoing the calibration the values are not close to 0, one of the
devices may be damaged: if the transmitter is defective, please contact
your SuperSonic Imagine representative, and if either the eTRAX™ or
VirtuTRAX™ is defective, please contact CIVCO or the reseller.
To perform the Needle Calibration Test, please follow the instructions
given on the screen in the 'Needle Calibration Test' menu.
