Using the Z90
Power
The Z90 accepts 7-24 Volts DC from either the supplied battery cables or AC
adapter. The
POWER
indicator will glow steadily when the light is powered on,
and flash when the light is powered off.
Turning the Z90 On and Off
Push and release the Z90’s
POWER
button to turn the light on and off.
Dimming
Turn the intensity knob clockwise to increase the Z90’s intensity, counter-
clockwise to decrease intensity. At full intensity the ‘Z’ logo will be upright.
Operating Modes
The Z90 operates in one of three modes:
WHITE , GEL ,
and
COLOR
. To switch
between modes push in and hold the top thumbwheel for ~1 second. The mode
indicators will show the current operating mode.
WHITE Mode
In
WHITE
mode the Z90 outputs daylight or tungsten white light. Push
the
DAY
or
TUNGSTEN
buttons to change the output.
GEL Mode
In
GEL
mode the Z90 outputs adjustable white light from 2500 °K -
9000 °K with ± GREEN color correction. Rotate the top thumbwheel to
adjust the color temperature in 50 °K steps. Rotate the bottom
thumbwheel to adjust color correction. The
SAT
indicator will glow
whenever color correction is being used.
COLOR
Mode
COLOR
mode lets you adjust the color hue and saturation of the Z90’s
output. Rotate the top thumbwheel and the output will cycle
continuously through red, green, blue, and every color combination in
between. Rotate the bottom thumbwheel to increase or decrease the
saturation of the current hue. The digital display will indicate the
percentage of saturation, and the
SAT
indicator will glow when any
color is less than fully saturated.
Presets
In
GEL
and
COLOR
modes you can save two of your favorite settings as presets.
The preset buttons
P 1 and
P 2 work like those on a car radio: To save a setting
push and hold the button for ~2 seconds. The button’s indicator light will flash to
show the current setting has been saved. To recall a saved setting push and
release the appropriate preset button.
Preset settings are retained even after you remove power from the Z90.
In
WHITE
mode the preset buttons are factory-set at daylight and tungsten.
