5.3.1.2 Displaying Min, Max or Average Values
The Digital Display widgets show the instantaneous channel value but can be
changed at any time to display minimum, maximum or average values. To
change the reading double tap in the lower line of the digital display widget
indicated right.
This will pop up a drop down menu that allows the user to select the display
mode as follows.
INST. = Instantaneous – display the data as it is read – default (real time
display)
MIN. Minimum - will display the minimum (lowest) value ever measured.
MAX. Maximum – will display the maximum (highest) value ever measured
AVG. Average – will perform a weighted average on all input samples at 10
samples/sec and average them as (last value + current value)/2 and display this.
Note – you can use the Filter on each channel to provide additional averaging.
The display indicated the current display mode in the lower left of the display
widget using the characters above - with the exception that NO indicator
is shown for real time (instantaneous) value. Maximum value is shown displayed
right.
