Introduction
The GF-1 is a 2 1/4" G-force meter capable of measuring G-forces exerted in an aircraft up to +-10g. The forces acting on
the aircraft are easily seen on a large backlit graphic display both numerically and graphically. The GF-1 also has the
facility to record maximum G-forces obtained in permanent memory as well as a temporary memory to record G-forces
reached from the time of power up. It also features 2 independent cycle counters to capture the amount of times a preset
force has been exceeded. The GF-1 is able to measure G-forces even if the instrument is not mounted exactly on the
vertical axis of the aircraft.

You have now calibrated both the horizontal and vertical G-force using Earth’s gravity as the reference. 5 Loading Factory default settings Pressing and holding the F1 and F2 keys simultaneously on power up will cause the GF-1 to load pre-programmed factory default settings. The following screen will be displayed:... - Page 7 The unit should not be cleaned with any abrasive substances. The screen is very sensitive to certain cleaning materials and should only be cleaned using a clean damp cloth. Warning: The GF-1 is not waterproof. Serious damage could occur if the unit is exposed to water and/or spray jets.

Page 8: Installation
9.1 Connection Diagram The use of an external 1A fuse is recommended. Connect the supply terminals to your aircrafts power supply. The GF-1 can be used on both 12V and 24V without the use of any pre-regulators. Ensure that the supply voltage will not drop below 8V during operation as this may result in incorrect G-force readings. - Page 9 GF-1 Operating Manual Page 9 10 Warranty This product carries a warranty for a period of one year from date of purchase against faulty workmanship or defective materials, provided there is no evidence that the unit has been mishandled or misused. Warranty is limited to the replacement of faulty components and includes the cost of labour.
