Esprit Digital 750 Operating Instructions
UP & DOWN Buttons
Select the required 'FUNC' as detailed above.
Single presses of the 'UP' or 'DOWN' buttons will increment or decrement the value by one.
Hold the appropriate button down to automatically increment or decrement the value.
Release the button when the required value is reached and then use momentary presses to
adjust if necessary.
NOTE: Attempting to exceed either the minimum or maximum values for any function will
cause the display to flash. If the sounder is turned on then this will beep to indicate an over
range condition.
FLASH CONTROLS & OPERATION
POWER Button
The maximum available output power of the unit can be selected by pressing the 'POWER'
button. Each press will select the next setting as indicated by the appropriate LED. This is
equivalent to having three units in one with three maximum values available: 250W-s, 500W -
s & 750W-s. This allows the user a certain amount of control over the flash duration. If a
short flash duration is important then always select the lowest 'POWER' setting and the
highest 'FLASH' setting possible for the required output.
For each 'POWER' setting the displayed 'FLASH' power is adjustable over a 5 f-stop range
(6 f-stop points). This provides an overall control range of 6 +7/10 f-stops in 1/10 f-stop
increments.
'F' - FLASH Display Mode
The FLASH mode is displayed by default and is indicated by an 'F' before the flash value as
follows:
Display Range X.X Description
Display Flash power value. Use 'UP' or 'DOWN' to adjust.
FX.X 5.0 to 10
The FLASH power is adjustable over a 5 f-stop range (6 f-stops) in 1/10 f-stop increments
using the UP and DOWN push buttons. The power is displayed in an easy to use decimal
form where each whole number represents 1 f-stop. The control has a minimum setting of
5.0 and a maximum setting of 10. A single press of either the UP or DOWN button changes
the value by 0.1 f-stop (1/10) to give a total of 51 values. E.g. If the current value shown is
9.4 then to reduce the power by 1 f-stop just reduce it to 8.4. The following table shows the
whole decimal numbers and equivalent fractional power ratio:
