® INTRODUCTION Thank you for purchasing the Heli-Max Digital Pitch Gauge. This product is intended to measure the angle on the helicopter’s main and tail rotor blades during setup. The gauge can also be used without the mounting plate for other tasks that would require a level. ® CONTROLS 1 2 3 4 10 11 12 5 6 7 8 1. Ruler 2. Blade Clamp 3. Mounting Plate 4.

OFF/ON Button: Press the button to turn the gauge on or off. The gauge will turn itself off after 5 minutes of inactivity. ABS Indicator: The gauge will be in ABS (Absolute Measurement Mode) when it is turned on. This mode uses 0 degrees as the reference point for all measurements. When the gauge is in this mode, you will see a small pointer on the left side of the display by the ABS sign.
® OPERATION For the most accurate pitch reading, the Heli-Max Digital Pitch Gauge should be reset so it is perpendicular to your helicopter’s mainshaft. The end of the motor on an electric model, or a flat top/ bottom section of the side frames should be good surfaces to use. Place the gauge on the area selected and press the ZERO button to put the gauge in REL mode.
Turn on Pitch Gauge. Extend both rotor blades so they are 180° apart. Slide the gauge onto one of the rotor blades. Position the gauge as close as possible to the blade grip. For maximum accuracy when checking the pitch of the other blade, position the gauge the same distance from the blade grip.
® BATTERY REPLACEMENT Remove battery compartment cover. Remove discharged batteries. Install (2) replacement CR2032 batteries. Please note that the positive side of each battery should be on top. Replace the battery compartment cover. The gauge does not need re-calibration after the batteries have been replaced. ® STORAGE If the gauge is not going to be used for a long time period, please remove the batteries to prevent damage to the contacts. ® SPECIFICATIONS Operating Voltage: 3.
