Recording Measurement Data
The Meter’s record feature collects measurement information
over a user-specified duration. This collection of information is
called a recording session. A recording session is made up of
one or more measurement records. Each record contains
measurement summary information covering the duration of the
record.
Each record contains the minimum, maximum, and average
value detected over the record’s duration. In addition to
measurement values, time stamps are also captured and saved
with each record. The time stamps consist of the record start
time, the time the maximum value was detected, the time the
minimum value was detected, and the record end time.
Some of a records data can be viewed through the Meter’s
Viewing Trend Data function. Viewing all the data that makes up
a record can only be viewed on a PC running FlukeView Forms
software.
There are two measurement record types that are captured
during a recording session: interval and event. An interval record
covers a user-specified interval. An event record has a duration
determined by the activity of the measured signal and can
interrupt an interval record. Even if an interval record is
interrupted, a record will end and a new interval record will begin
when the scheduled interval time expires.
52
Event records are triggered by the measured signal varying more
than an adjustable percentage of the value measured at the start
of the record. This adjustable percent is called the Event
Threshold for recording. In addition to the values and time
stamps mentioned above, an event record also stores whether
the signal was stable or unstable during the event record
duration. To be classified as stable, the measured signal’s value
must stay within the selected percentage of the start value for at
least one second. Measured signals that exceed the percentage
threshold in less than one second are classified as unstable. See
the “Setting the Event Threshold Value” section later in this
manual.
A record ends when one of the following occurs:
A recording session termination can be caused by one of the
following:
For temperature measurements, the AutoHold
threshold is a percent of 100 degrees. The default
AutoHold threshold is 4% of 100 degrees, or 4 degrees
Celsius or Fahrenheit.
The start of a new interval record.
A range overload, causing the Meter to change range.
A non-ranging overload, when in manual range or the
highest range.
The measured value changes more than 4 % of the
measured value at the start of the record.
The recording session terminates.
