## ⚙️ Key Features

-   117 product designations in all

## 🔌 Function

Measures the pressure a cylinder builds on the compression stroke, so the sealing of rings, bore and valves can be judged against specification.

## ⚠️ Common Signs of Failure

-   Readings drifting, sticking or not repeating between cylinders
-   Needle not returning to zero when the gauge is bled
-   Leaking hose, adapter or non-return valve giving low readings
-   Gauge glass cracked or the face fogged
-   Adapter threads damaged so the seal at the cylinder is poor

## 🛠️ Service Notes

-   A leaking adapter reads as low compression, so check the tool before condemning an engine
-   Measuring instruments need periodic calibration checks if the readings are to be relied on
