Choose the source for the switch input The most useful switch choice for dyno testing is the WOT Switch If the program sees this in the DataMite Il s configuration it automatically uses this switch to determine the beginning and end of dyno runs See Figure 2 17b for setting this Important Some channel names have special meaning to the Keep Calib Help Cancel Print DataMite program For example if you are recording a temperature you could just select one of the several Thermocouple calibrations like Std Thermocouple Misc and then name it yourself as Exh 2 This will get you a temperature reading but some of the program s features may not work correctly In this case displaying this channel in the Current Readings screen s Exhaust Temp bar graph and analyzing average exhaust temperatures and exhaust temperature spread would not include this channel Therefore try to pick a Calibration which is most appropriate for that particular channel and sensor The Data Name for the channel can be most anything you want as this is not used by the program for anything critical just to label graphs and reports Menu Commands Back Simply closes this menu and returns you to the Main Screen If you made changes to these specs you will be asked if you want to keep them for the current test If you answer Yes the results of the current test may be changed based on these changes This is good if you are correcting a mis

32. If not you will have to make one There are basically 2 ways to do this shown in Figure A5 4 If you bolt a calibration arm to the dyno case you will probably add a certain amount of torque to the dyno unless the arm is perfectly balanced from side to side The additional weight of the arm does not matter as it is absorbed in the bearings holding up the dyno itself The permanent Calibration Arm method of Figure A5 4 is more accurate as you don t have to be so exact about the balance of Figure A5 4 Types of User Fabricated Dyno Calibration Kits Temporary Calibration Arm Must be perfectly balanced Permanent Calibration Arm Must remain installed after so it does not add a torque when you install it the calibration is done since it adds a torque to dyno Bolt to Temporary Arm can be Bolt to removed when done Dyno Case Hang weights Hang weights from here from here Torque Arm for Torque Arm for calculating calib calculating calib bration torque bration torque the calibration arm If you choose that method be sure the arm does not stick out so much you keep banging your knee into it You will also need a known weight that will put you in the upper end of the torque range you will be measuring For example if you want to measure up to 100 ft lbs of torque and the Torque Arm of your calibration arm is 15 long out from the center of the dyno you would need a weight of about 80 Ibs Required Calibration Weight Desired Torq
