1. Disconnect an electric socket of the gauge of a detonation and remove the detonation gauge. Fix the detonation gauge in a vice and connect the voltmeter between plugs 1 and 2. |
2. A hammer sharply strike on a vice and observe of voltmeter indications. |
3. Check up that the detonation gauge gives out peak pressure (less than 1). |
