Note: The meter must be set to the inches H2O mode.Note: The overall system accuracy for the intended use is 20%.Choose the proper orifice for your application.The Small Orifice (A) is for use with engines with 400 hp and less. The Large Orifice is for engines with greater than 400 hp.Once a reading of inches is obtained with the meter, convert to cfm using the charts in section titled ""Charts"" in this manual. There are charts for engines 400 hp and less, and engines over 400 hp.Operation
Obtain a reading of inches H2O with meter.Note: Do Not use the MIN/MAX AVG function for this reading.
Convert reading to Cubic Feet Per Minute (CFM) using the charts in section titled ""Charts"" in this manual. There are charts for engines 400 hp and less, and engines over 400 hp.
Multiply CFM by 60 (CFM x 60) to convert to Cubic Feet Per Hour.Charts

Engines 400 hp and greaterMeter Power
The 368-8645 Tool Kit (CRANKCASE PRESSURE) uses a 9V battery for power. If the meter does not switch on when the "POWER" button is pressed or if the display shows "BAT", replace the battery.When the "POWER" button is pressed, the meter performs a short self-test and reverts to the settings in place when the meter was last turned off.Automatic Power-off Feature
In order to conserve battery life, the meter has an automatic power-off feature (after 20 minutes). To defeat this feature, press and hold the "HOLD/ZERO" (9) button while turning the meter on. Release the "HOLD/ZERO" (9) button when "'n'" appears on the display. The meter will now remain on until the user turns the meter off or until the battery weakens. The Auto Power OFF feature will be reactivated the next time the meter is turned off and then on.Fittings Connection
Connect tubing to the P1 (3), P2 (1) (or both) input ports. If both inputs are used (differential mode), the meter displays a positive pressure reading if the P1 (3) pressure is greater than P2 (1) and a negative reading if P2 (1) is greater than P1 (3) .Zero Adjust and Offset function
To ZERO the meter, before use and without fittings attached to the meter, press and hold the "HOLD/ZERO" (9) button for 3 seconds or until the display shows all zeros (0000) then "0.00".To OFFSET meter readings: Press the "DIF" (7) button while taking a measurement. Subsequent readings will represent the difference between the current measurement and the measurement that was on the display when the "DIF" (7) button was pressed.MIN-MAX-AVG Record Mode with Elapsed Timer
The "RECORD" (8) function tracks the maximum "MAX" (6), minimum "MIN" (18), and average "AVG" (18) readings with a time stamp. The elapsed timer is displayed on the lower right-hand corner of the LCD. The elapse
