Setting options are from 00.00s to 99.99s.

Note: 0 seconds should not be used with TV-type high wattage lamps, where the minimum
recommended is 0.05s. Faster response times should be used with care, and with lower
wattage loads.

Press EDIT and using the <<<< and >>>> buttons, choose T-IN or T-OUT
[enabled when square brackets are shown] and set it to the required time using
the rotary encoder.

Using the UP and DOWN buttons to address other channel numbers (unless all
dimmers are being set-up together).

Press ENTER to leave the menu, then either SAVE (to record the changes) or
CANCEL (to leave the previous settings unchanged).

Dimmer curves

Dimmer curves (dimmer laws) are used to adjust the relationship between control
level and light output. This enables the dimmer to be fine-tuned to accommodate the
preferences of a live audience or a television camera. There are 8 factory standard
dimmer laws, and a provision for a further 26 custom selectable curves in later
software releases. The factory default law (0) is Linear Law. The list of dimmer
curves is as follows:

0 = linear relationship (standard)

1 = BBC specification

2 = S-Law

3 = inverted (control = zero, dimmer = full etc.)

4 = Fluorescent (minimum 50%)

5 = Fluorescent (minimum 30%)

6 = Linear (offset at 50%)

7 = Pulse effect (light switches on and off as the control fades up and down)

8 = Solid state switch

9 = 2kW linear curve

10 - 15 custom programmable via DimSTAT (future expansion)

To select a dimmer curve:

Select CONFIG. from the home menu, and press EDIT

The screen shows the individual channel number (or ALL if the dimmer set-up
scheme copies characteristics to all dimmers in the device) as follows:
