Chapter 4
Using Memory & Communications Features
Introduction
Chapter 4 shows you how to use memory and
communication features available on the meters.
Note
Memory, Logging, and Save features apply to the
189 only.
Types of Memory
The meter has two types of memory data: saved readings
and logged readings.
Saved Readings Memory
Saved readings include primary and secondary readings
and functions, the time stamp, and display icons
representing various features in effect.
Logged Readings Memory
The logging interval (Log Int) can be set using the meter
or FlukeView Forms. You can view the average reading
for each logging interval on the meter’s display. A
scheduled logging interval may contain stable and
unstable logged readings. Unstable logged readings
represent unstable events as defined by the AutoHOLD
function. See the Specifications.
To provide more detailed logging information, the meter
also stores the high, low, and average value for each set
of stable and unstable logged readings. You can only
access these logged readings using FlukeView Forms.
Some of the logged readings can only be accessed using
a PC running the FlukeView Forms software. FlukeView
Forms displays the data in graphical or tabular form,
prints, and stores the data.
