RH DESIGNS STOPCLOCK PRO 110v
Includes:
• Mains lead
• enlarger/safelight connectors
• instructions.
Features:
• Base exposure time 1.0 seconds to 240 seconds, in steps of 1/24th to 1/2 f-stop
(or of 0.1 or 1.0 seconds in linear time mode). Time is controlled to 0.01 seconds.
• All exposure times are set in coarse and fine steps of actual exposure rather than
simple seconds, producing consistent changes on the paper. The fine step size is
1/24th f-stop (approx. 2%). The coarse step size can be set to 1/2, 1/3, 1/4, 1/6 or
1/12 of a f-stop. Coarse/fine button toggles between 1/24th and the set coarse
time step.
• Nine subsequent exposure times can be programmed, each calculated either
relative to the base exposure or the total exposure time thus far. Burn-in exposures
are set in steps of 1/12th to 1/2 f-stop. If the base exposure is changed, the burn-in
exposures are recalculated to maintain the density relationships.
• Two completely independent channels, each having separate base and burn-in
exposure times.
• Split-grade mode, in which exposure can be controlled using one channel while
the second can be used to adjust contrast. Equivalent contrast is displayed in
steps of 0.1 grade.
• Automatic test strip mode, for quickly producing test strips with 1/12th to 1/2
stop increments either as an incremental exposures or separate complete
exposures.
• Exposure Compensation of +/-20% to allow for dry-down or and/or toning with
respect to a test print.
• The clear yellow LED display brightness can be set to one of three levels. The
display color has been chosen to be safe for both colour and black and white
printing.
• Audible beep at the end of each exposure, and optional seconds tick whilst the
enlarger is switched on.
• Rugged steel enclosure and high quality components for reliability. Illuminated
control buttons.
• Can be connected to our ZoneMaster for exposure metering.
• Automatic safelight switching; manual (focus) mode; 750 watts (500 watts in
115v versions) switching capacity
• A footswitch is available as an optional extra for hands-free operation – see the
accessories page.
• Exceptionally easy to use! All timing, including switching between channels, can
be controlled from the footswitch.
