Data Hold
Press the
HOLD
button to freeze the displayed reading. The 'H' hold icon will appear on
the upper right-hand side of the display. Press the
HOLD
button again to return to normal
operation (the 'H' hold icon will disappear). When hold function is enabled the analog bar
graph will continue to display level changes.
Peak Hold
The Peak Hold feature allows the meter to captures light level changes that occur in as
little time as 100us. Press the
PEAK
button momentarily and the ‘P+’ icon will appear on
the LCD. The meter can now measure a fast acting light peak and display it on the LCD.
To exit the Peak Hold mode, press and hold the
PEAK
button until the ‘P+’ icon
disappears.
NOTE: If the
PEAK
button is pressed
momentarily
rather then pressed and held when
exiting the Peak mode, the meter will display ‘P-‘ which is a function reserved for future use
and should be ignored.
Relative mode
Measurements can be displayed as a difference between actual light level and a stored
reference value. To store a reading as a reference, press the
REL
button when the desired
reference measurement is on the LCD (the triangle icon will appear steady in the upper
left-hand corner of the LCD). All subsequent displayed readings will be “relative” to the
stored reference value. For example, if the reference value is 100 and the actual light level
is 125, the meter will display 25. To view the reference value, press the
REL
button again
so that the triangle icon begins to flash. The displayed value will be the reference value. To
exit the Relative mode, press and hold the
REL
button until the triangle icon disappears.
