9U-5795 AC/DC Current Probe to measure Hz.Connect the 1U-7505 High Voltage Adapter to frequency channels 7, 8, or 9 and connect the banana plugs on the current probe into the high voltage adapter. Refer to the Tool Operating Manual on the 9U-5795 and turn on the current probe. Connect the probe over a wire carrying the current whose frequency is to be measured. Take the reading as described in the previous section.Using Dataview to Measure Engine Set Point
Dataview contains an engine set point feature that can be used for measurement of the set point rpm of Cat diesel engines which have an external mechanical fuel injection pump with a rack contact on it. These are usually older Cat engines. The set point (formerly called the balance point) is 20 rpm more than the balance point of the engine. Because of this, 20 rpm must always be subtracted from the measured set point to find the balance point rpm listed for the engine. This measurement was formerly measured using either 9U-7401 Multitach II , or the 6V-4060 Engine Set Point Indicator and a 6V-2100 Multitach . For a detailed description of measuring engine set point and a full explanation of set point, balance point, and full load rpm, refer to the Special Instruction, SEHS7931, for the 6V-4060 Engine Set Point Indicator .Two set point inputs are provided, CH7 and CH8. The CH7 set point input works with frequency channel 7 for rpm measurement, and CH8 works with channel 8. An 8T-5111 Adapter Cable and a 1P-7446 Rack Cable are both required to connect the set point inputs to the engine. Any type of rpm sensor can be used. To measure set point, set up the rpm in the corresponding channel, and turn on the set point display by double clicking the rpm channel to bring up the "Define Frequency Channel" dialog box. Select the "Set Point Attached" box and the "Set Point" display will always be shown with that frequency channel display. Measure set point in the normal manner described in the Special Instruction, SEHS7931. The set point rpm will be held on the display when set point is reached. To take another reading click the arrow on "RESET" and measure set point again.Measuring Fuel Flow with Dataview
Dataview can be used to measure fuel flow using the fuel meters from the Cat 1U-5430, 1U-5440, or 1U-5450 Fuel Flow Monitor Arrangements. A 1U-9500 Fuel Flow Communicator is also required. Since the output of the Cat flowmeters is a nonstandard digital current loop signal, the fuel flow communicator is required to convert this output signal into a frequency which can be measured by Dataview.Use these steps to read fuel flow with Dataview:
Refer to the Special Instruction, SEHS8874, "Using the Cat Fuel Flow Monitor System" for installation of the flowmeters on the engine to be measured. The 8T-9300 Fuel Flow Monitor can be used during installation to verify proper operation.
