Enabling and Disabling the Smoothing Mode When an AC input signal is noisy or changes rapidly, the smoothing mode may display a steadier reading. To enable or disable the smoothing mode, press the softkey labeled Setup and position the menu selector next to the menu labeled Instrument. Next press the softkey labeled Instrument and position the menu selector next to the menu item labeled Smoothing. Press the softkey labeled Edit to move the cursor to the on or off selection. Use 7 and 8 to switch the smoothing mode on or off. Using Other Setup Options Additional setup options hold information about the Meter as well as some general Meter functions. The Meter Info selection lists the serial number, model number, firmware version, calibration date, and calibration counter. Operator name, company name, site name, and contact information are also displayed when this information has been loaded into the Meter from FlukeView® Forms software. The Calibration selection allows a qualified calibration technician to enter a password that allows the Meter to be calibrated. See the 287/289 Calibration Information document to calibrate the Meter. The Secure Erase option allows user-accessible memory to be erased as required by Homeland Security regulations. Meter calibration is not lost when this low-level erase is performed. As new Meter features are created, the latest version of software can be downloaded to the Meter from Fluke's support web page using the Software Update option. True-rms Digital Multimeters Using Memory Using Memory The Meter has memory for storing individual measurements, measurements collected over a specified duration, and measurement events. All stored data can be viewed on the Meter or downloaded to a PC through the Meter's infrared (IR) communication link using FlukeView™ Forms. See the "Using Communications" section for more information on communicating with a PC through FlukeView Forms software. Storing Individual Measurement Data For all measurement functions, a snapshot of the screen data is saved by pressing the softkey labeled Save. Except for the minimeasurement in the status bar, the display freezes and the Save menu appears. Two choices allow either saving the data under a previously selected name or choosing another name by pressing the softkey labeled +Name. See the "Naming Saved Data" section later in this manual. The displayed data is stored along with the date and time of day the save was performed. For MIN MAX and Peak, the displayed summary data can be stored at any time by pressing the softkey labeled Save, thus preserving a snapshot of the session at that moment. Naming Saved Data The Meter has a list of eight preset names under which measurement data is saved. Multiple records can be saved using the same name. For example, one preset name is Save. The first time a save operation is performed with that name, Save-1 is used to name the record in memory. The next time the Save name is used, the number increments to 2 and the record is 49
