Balance reset
Selecting this option resets the potentiometer positions for the P and Q channels for each
frequency to 50. This will often be done prior to manually balancing the head (usually at
31kHz). Remember to run the Auto configure process afterwards.
Tap on the button to start the balance reset process.
VF Drive
Purpose
The VF Drive screen is displayed by tapping on the VF Drive icon in the
Service
screen.
Within this screen the the transmitter drive for all available operating frequencies are set up to
maximise sensitivity of the detector. This is carried out during the manufacturing process so should
not need adjustment under normal operating conditions.
However, if any of the electronics are replaced it is recommended that the setup is repeated. This is
normally done using the AutoBalance feature by selecting the Auto configure option which
automatically makes any P and Q channel balance adjustments necessary for each of the available
frequencies.
Manual adjustment is also possible and this is carried out by Loma Service Engineers when required.
