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.
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 mini-
measurement 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
