Unit will automatically turn off after 2 minutes if no keys have been pressed. GREETING MESSAGE The PerformAIRE By ALTRONICS O2 EQUIPPED VERSION 6. * "O2 EQUIPPED" will only appear if the unit was purchased with an oxygen sensor. DATA BASE #1 ET MODE Selected Multiple Run Prediction Wind Prediction Enabled Second greeting message above will show the following info about the “Setup” of the unit: Data base, prediction mode, prediction type, and wind effect. TAKING AIR SAMPLES 1. Place PerformBJSF in an area that will constantly expose it to the air you will be racing in (out side of trailer). 2. Do not place your hand or any other object near the air vent or black probe while PerformBJSF is in use. 3. Keep PerformBJSF out of direct sunlight. 4. Do not place PerformBJSF near soil or grass as it may pick up additional humidity. 5. Even though the PerformBJSF's sensors can stabilize very quickly, residual heat left in the enclosure when PerformBJSF is moved from one environment to another may take more time to dissipate. Example: When you arrive at the track and PerformBJSF out of your 70-degree transporting air, you must let it sit for fifteen before taking this time the PerformBJSF enclosure and black with the environment and allow accurate readings the rest of Allow time appropriately 3 temperature. If the PerformBJSF is OXYGEN SENSOR equipped, allow twice as much time to stabilize. UNIT DOES NOT NEED TO HAVE POWER ON IN ORDER TO STABILIZE!!!!!! ! 6. Although the PerformBJSF is reasonably durable, it can be damaged if dropped or abused. Keep this in consideration when using and storing the PerformBJSF. 7. For best results only turn PerformBJSF on when taking a reading. **IMPORTANT** Units with oxygen sensors only: When using a unit with an oxygen sensor that is set to Oxygen Altitude mode, the unit must remain stabile while in use. If movement has agitated the unit it must remain stable for 15 minutes before taking air samples. Unit does not need to have power on to stabilize!!!! ******Important****** It often takes a number of trips to the track to acquire the above- recommended data in order to produce accurate results. Because of this, we suggest using the following method until enough data has been acquired. Gasoline burning engines: A 200’ rise in DA typically yields a 0.01sec slow down versa for a drop in DA. Alcohol burning engines: A 400’ rise in DA typically yields a 0.01sec versa for a drop in DA. For TS racers: Typically the TS ratio is 3:1. This means is takes 0.03sec in the timer to move the car 0.01sec. Use this information with the above DA change set up your timer. 4 KEYPAD FUNCTIONS MENU/ON key - Turns unit ON and allows the unit to leave any current menu and return to the MAIN menu. SCROLL key - used to view runs that have been stored in the data base. CLEAR/OFF key – Turns unit OFF when pressed from MAIN menu and allows runs to be deleted from the data base and allows the user to reenter a value if the wrong key was pressed. ENTER/HOLD key - must be pressed after keying in a value to confirm the value is correct. When pressed in CURRENT DATA mode the air sample is held in memory and can be used for data entry later on. MENUS MAIN MENU - When unit is turned on the MAIN menu automatically is displayed after the greeting message. The user can make of the six following choices at this point: SAMPLE AIR = 1 SET UP = 2 RUN ENTRY = 3 PREDICT = 4 Hit the “MENU” key again and see: DOWNLOAD =5 SET CLOCK =6 BAD RUNS =7 AUTO POWER OFF =8 Hit the “MENU” key again and see: PAGER SETUP =9 * BATTERY CHECK =0 *...
