Display Functions and User Interface
LOG
justed using the UP and DOWN ARROW keys to increase or decrease the scale range.
The available range selections are +/- 0.01, +/-0.1, +/-1.0, +/- 10.0 °C. The vertical
scale center is calculated automatically and displayed.
The graphing function may be used on models 1523 and 1524. The 1523 will al-
ways display Channel T1. When using the 1524 instrument, Channel T1 is selected
by default, the user may select between Channel T1 and Channel T2 by pressing the
“NEXT” key. In this mode, data for both Channel T1 and Channel T2 graphs are main-
tained simultaneously. Only one channel may be displayed at a time while the other
channel is held in memory. When a channel is switched, the graph is replaced with
data from the new channel.
While in the graphing mode, the channel being displayed is shown on the top left area
of the display, ‘T1” or “T2”. The top right area of the display shows the statistical
option, followed by the statistical value for the displayed channel in numeric format.
The most recent temperature measurement is displayed in numeric format above the
graph and just below the stats value. The statistical option selection may be changed
by pressing the “STATS” key until the desired option (MIN, MAX, AVE, or STD)
appears on the display. Note: Standard deviation will be shown on the screen in this
mode as STD rather than the usual STD DEV.
The graph is cleared when the display mode is changed to or from a numeric format,
or if the temperature units are changed. In addition, entering in the SETUP Menu will
cause the graph to refresh.
4.15 LOG
The Auto-Log feature allows the user to setup data collection and storage on both
channels. This menu selection allows the user to setup the interval of the logged data,
a tag or identication label, see the available memory for storage, and session start &
stop. This Auto-Log feature is only available in model 1524.
The Auto-Log feature is affected by the Auto-Off function. If the Auto-Off function is
used and the unit turns off during a logging session, the logging session will be termi-
nated and the unit will restart with the Auto-Log turned off. It is recommended that the
Auto-Off function be turned Off before starting a logging session.
4.15.1 Free
This feature indicates the amount of memory available for storage, in terms of %
memory unused. It also indicates how many bytes of memory are available for use.
4.15.2 Interval
This feature allows the user to select the interval used by the processor to take new
data. The available selections are Auto, 1, 2, 5, 10, 30 and 60 seconds If logging with
a model 1524 using two active probes and a 1 second interval, a second of data will be
skipped approximately every three seconds in order to have unique values in every set
of stored data. When the unit is in Auto interval sampling, the Fast Scan Mode Speci-
cations apply. Refer to Table 15 on page 21, Fast Scan Mode Specications and Table
16 on page 21, Sample Interval per Channel in Seconds
