  • Page 6: Product Description

    The tachometer frequency is adjustable as a ratio of the respective output signal frequency. The 4830B also features the ability to analyze a vibration signal using a Fast Fourier Transfer function. This allows a voltage proportional vibration signal to be inputted to the instrument thereby providing an indication of both frequency and magnitude.

    3.0 Basic operation 3.1. Menu structure The simulatormenusare accessed via the three menu keys as shown in Figure 2below. Figure 2: Menu structure 3.2. Home screen The home screen is in two parts, upper and lower. When the simulator is turned on, the upper screen becomes the default.

  • Page 9: Editing Screen

    Figure 4: Home screen, lower 3.3. Editing screen The editing screenis accessed by pressing either the left or right arrow keys when in the home screen. Similar to the home screen, the editing screens are in two parts, i.e. primary and secondary parameters. Scroll up or down with the arrow keys to move between parameters and the upper and lower screens.

    edit screens. When a secondary parameter is changed the g level value will change as a result. See section 4.2.2for details. 3.4.1. Default profile The default profile is loaded for convenience when the simulator is turned ON. The default profile contains pre-set simulation parameters which cannot be permanently overwritten.

    therefore only connect an external signal to the Tach / FCN BNC once the FFT function has been selected . It should be noted that the maximum input capability of the FFT input is 5V pk. See section4.7for further details on the operation. 3.5.2.

  • Page 12: Power

    Figure 9: About screen 3.6. Power The simulator is primarily a battery powered instrument. Power comes from an internal rechargeable Li- on cell pack. A universal power adapter is supplied with the simulator which can be used to charge the internal battery or to power the simulator from an AC outlet.

    4.0 Detailed operation 4.1. Parameter editing The editing function is the same process for all parameters with the exception of Type. From the home screen, press either the left or right arrow keys to enter the editing screens. Using the up and down arrow keys, move the cursor (inverted text) to the parameter to be edited, and select by pressing the ENTER key.

    A short message follows indicating the profiles are being saved to memory. The display will now look like this: Figure 17: Profile after save PressENTER to load and view the profile. The upper home screen now shows the user profile name. The profile parameters can now be edited as previously described in paragraph 4.1.
