for SH-V4A

1. Foreword

Congratulations on your purchase of a SpeedoHealer calibrator unit.

At HealTech Electronics Ltd. we are committed to produce the best calibrator devices

available and we would like to thank you for choosing our product.

The Harness Kits required for installation are supplied separately. Please make sure you

have received the correct wiring harness kit for your vehicle.

After installation, we recommend using our online calculator to calculate the required

calibration value and to generate step-by-step programming instructions. You can also

use our SpeedoHealer calculator app, available for iOS and Android devices.

2. Features Explained

Simple User Interface: Easy to program, review and update the stored parameters.

Extended calibration range: -99.9% to +9999.9% in steps of 0.1%

This means the signal can be adjusted from 1/1000 to x100, in increments of 0.001. This

range is efficient even for the most radical conversions and suitable for all kinds of

custom applications as well (e.g. different engine-gauge combination, bike engine

powered cars, etc).

Dual-Bank Memory: Allows storing two independent calibration values and switching

among them is possible by the press of a button. There is a clear, visual confirmation of

the active bank and value in use. Perfect for areas where you have summer and winter

tires of different sizes.

Km/h conversion: Change from Km/h to MPH by the press of a button.

Compact dimensions: Full SMD design. The smallest and lightest calibrator ever built.

High-speed CPU: 32-bit processing ensures high accuracy and immediate response to

the input signal with no lag. Ultra-low power consumption and auto stand-by.

Robust design: 100% weather proof. Every unit is fully tested, guaranteed to work.

All leads are protected against reverse voltage, short circuits and high energy transients.

Wide operating range: +3V to +19V at -40C to +80C (-40F to +176F)
