6.00 BUILT-IN MEMORY SYSTEM
The DTMX Built-In Memory system can be configured to operate in one of the
following modes: Standard Memory, Standard Memory With No Auto Power
Off, On-Demand Data Logging and Continuous Data Logging. The latter two
are part of the Extended Memory. Data recorded in the Standard Memory or
the Extended Memory can be recalled to the LCD Display for viewing or down-
loaded to a printer or PC. To set the Memory Mode, refer to Configuring Dip
Switches, Section 5.30.
6.10 Standard Memory Mode
The DTMX takes 62 tension measurements per second and displays the aver-
age of these measurements over a user-selected Display Update Rate of 0.5, 1,
2 or 4 seconds. The Standard Memory system checks each displayed value and
retains the Maximum, Minimum and Peak tension values which occurred dur-
ing the Measuring Interval. The Measuring Interval is started and stopped by
pressing the key.
Maximum Value: highest displayed
value during measuring interval
Minimum Value: lowest displayed
value during measuring interval
Peak Value: highest transient value
of all of the measurements used to
calculate each displayed value
Note: The “M” indicator on the LCD display will flash on and off, indicating
that the Standard Memory system is activated.
