3-4-3-1 “Average” Measurement Mode
When the AVG annunciator on the left side of the display
area is visible, a six-minute running average is maintained
by the unit. Power density is sampled every 3.6
seconds. During the first six minutes (i.e.-360 seconds
or 100 measurements), the running average of all
measurements taken will be displayed. After six minutes,
each "new" measurement will replace the measurement
taken 363.6 seconds prior to that "new" measurement.
Therefore, the average of the most recent 100
measurements will always be displayed.
The average of the latest 100 measurements is also
compared by the unit to the alarm warning level set by
the operator (paragraph 3-4-2) to determine the %
ALARM LEVEL ratio. (During the first six minutes of
operation, the running average of all measurements taken
will be compared by the unit to the alarm warning level
set by the operator to determine the % ALARM LEVEL
ratio.) If the % ALARM LEVEL ratio reaches 100%, the
unit's alarm circuitry will be activated, the red LED and
the ALARM annunciator on the LCD will flash every 3.6
seconds, and the audible alarm will sound every 3.6
seconds.
3-4-3-2 "Instantaneous" Measurement Mode
When the INST annunciator on the left side of the LCD
display area is visible, the measured power density is
sampled and displayed every 1.8 seconds. (Note that the
Model HI-3510 saves data for six minutes regardless of
the display selected. Switching between "Average" and
"Instantaneous" does not affect the data being stored.)
