LEMAGŪ LS Peak Pressure Indicators are measuring the firing pressure of internal-combustion engines. In order to be free of residues, the indicator valve should be shortly blown through before starting the measurement. To take readings the instrument has to be connected to the indicator valve by means of a standarized connecting nut.
The LEMAGŪ-LS Peak Pressure Indicator is now ready for use. When the indicator valve is open the pressure gauge will rise and will remain on the maximum. By notice this value, this indicator valve must be closed and the instrument has to be reseted by using the vent screw fixed at the side. After that, the LEMAGŪ LS is ready for taking new readings.
