6.6 Output Intensity Modes
6.6.1 The X-Cite
®
exacte can be operated in two different output modes: Relative and
Absolute .
Relative Mode :
Intensity level is adjusted and displayed as a percentage of the lamp’s current
maximum output. When operating in relative mode, intensity is displayed using
three digits (“
XXX
”) on the display screen.
Absolute Mode :
Intensity level is calibrated in watts, and can be adjusted and displayed in terms
of the actual output power in watts. When operated in absolute mode, intensity is
displayed using four digits with a decimal point (“
XX.XX
”, “uXXX”, “X.XXX”, or
“XXX.X”
) on the display screen. Formatting of the digits will indicate whether
units are watts, milliwatts, microwatts. Scale will auto adjust as appropriate.
NOTE: Absolute Mode is only accessible only when the X-Cite
®
exacte has been
calibrated with an X-Cite
®
Radiometer or X-Cite
®
Power Meter (see
section 7 ) and the CAL LED on the front panel is on.
6.6.2 To toggle between Relative and Absolute intensity modes in a calibrated system:
Ensure that the display is showing an intensity value (i.e. not in Lamp Hours
Mode).
6.6.3 Press MODE and release after 1 second.
NOTE:
Some rounding may occur when toggling between relative and absolute
display modes, unless the iris setting is a multiple of 5% (the calibration
points).
6.7 Adjusting Light Output
6.7.1 The X-Cite
®
exacte includes an iris to adjust the level of illumination.
Adjustments can be made in increments as small as 1% of maximum output.
Since there are 100 individual intensity steps, for convenience, there is the option
of adjusting in either COARSE or FINE mode.
6.7.2 Press the MODE button to select either the COARSE or FINE mode, which will
be indicated by the LED
’s to the right of the display.
