ETS-Lindgren HI-4416 Numeric EMF Readout Unit - Manual (Page 22)

22 Operation www.ets-lindgren.com
Clear Data —Clears all readings out of data log memory.
To perform this operation, press and hold the Clear Data keypad. The characters
"clr" will flash on the display for approximately two seconds. Continue pressing
the keypad until "000" appears on the display (these characters will not flash),
data log memory is now cleared. When you release the keypad, the system
readout returns to the measurement mode.
If this keypad is released while the "clr" characters are still flashing, data log
memory is unaffected. This helps prevent accidental erasing of data.
Log —Saves the current measurement in data log memory.
Pressing the Log keypad saves the reading in memory as this occurs, the
readout momentarily displays the three-digit identification number of the reading.
The data stored includes values, units of measure, over/under range indication
and active axes. Up to 150 measurements may be stored. When data log
memory is full, any additional log operations replace the value previously stored
in location 150 with the new value; all other memory locations remain
unchanged.
If this keypad is pressed for longer than two seconds, the just-logged data is
displayed
Prev —Accesses the last value stored in data log memory.
When the key is pressed the three-digit identification number of the stored value
is displayed for approximately one second then the stored value is displayed.
The readout continues to display this value as long as the Prev key remains
pressed. Approximately two seconds after releasing the key, the HI-4416 returns
to the measurement mode. Successive operations of the Prev key decrement the
displayed value toward the beginning of memory (value 001). If the key is
pressed while viewing value 001, the readout "wraps around" to the highest
stored identification number.
