The HPM5 Tire Gauge is designed for motorsport professionals, offering precise tire pressure and temperature measurements. In this guide, we’ll show you how to set up and use the Quick Functions for Pressure & Temperature, making your workflow faster and more efficient.

What Are Quick Functions?

Quick Functions allow you to instantly switch between different measurement modes on your HPM5 instrument. The display shows which buttons to press, so you can activate or deactivate functions effortlessly—without needing to check the manual.

1. Pressure Offset – Hide the Real Pressure Value

The Pressure Offset function lets you apply an offset value to the displayed pressure, concealing the actual measured value. This is useful for strategic purposes, such as hiding your tire pressures from competitors.
Example: Offset of 1.1 BAR

• If the real pressure is 1.394 BAR, the display will show 2.494 BAR (1.394 + 1.1). 
• This function also works when measuring in PSI.

2. Temperature Measurement Modes – Choose Your Preference

HPM5 offers two modes for measuring tire temperature:

• EXT - MID - INT: Follow a predefined sequence measuring from the outer to the inner part of the tire.
• T1 - T12: Measure up to 12 tire temperature points freely, without following a fixed sequence.

3. P/T Mode – Automatic Pressure & Temperature Measurement

The P/T Mode allows the HPM5 instrument to automatically switch from a digital pressure gauge to a tire pyrometer following a predefined sequence. This ensures a fast and structured data collection process, essential for accurate tire analysis.

How it Works:

Once activated, the instrument will guide you step by step through the following sequence:

• ✅ Measure tire pressure
• ✅ Measure outer tire temperature
• ✅ Measure middle tire temperature
• ✅ Measure inner tire temperature

This mode automatically switches between pressure and temperature measurement, making data collection faster and more efficient.

4. Pitstop Mode – Fast and Accurate Pressure Adjustments

The Pitstop Mode allows you to quickly measure and adjust tire pressure during a pit stop without pressing additional buttons.

How It Works:

1. The instrument automatically records the pit-in pressure when you enter the pit.
2. You release air until you reach the desired target pressure.
3. The instrument then automatically saves the pit-out pressure without pressing any buttons.

This function helps teams make fast and efficient pressure corrections during PitStop.

5. HOT tire Function

By default, each session records cold and hot pressures, along with the difference between them. However, when the HOT function is activated, the session stores only four pressure values (or two for two-wheel vehicles).

For example, if you only need to measure the pit-in pressures, activating the HOT function allows the instrument to save a session with just the four recorded pressure values.
