Haltech E6K - Manual (Page 65)

NOTE: If you ever wish to return the E6K to the factory barometric pressure
settings
then enable the Barometric Lock in the Fuel Set-up page and set the
Barometric Pressure Lock to 1013 mBars. These are the factory settings.
Method 3
Method 3 requires you to access the Fuel Set-up page and adjust two fields. Make sure the
Barometric Lock is Enabled. This tells the E6K that you are going to lock a particular value in
as the barometric pressure value. The next field down allows you to set a particular value.
This value should be the average barometric pressure the engine will be operated in. These
two fields are located at the bottom of the Fuel Set-up page:
Note that barometric pressure changes regularly and that Method 3 is only a basic approach at
barometric compensation. Set the Barometric Pressure Lock at xxxx mBars, where xxxx is the
pressure you require, say 1000mBars. When completed the E6K will assume that the
environment always operates at 1000mBars barometric pressure. It will then look at the
Barometric Correction Map located under the Maps pull down menu and locate the
1000mBars section of the correction map. Whatever the height of the bar corresponding to
1000mBars will be taken as the overall enrichment %.
For example, 1000mBars might correspond to the following highlighted bar on the
Barometric Correction Map:
