PROGRAMMING
to read directly in HZ or RPM with a 60 tooth gear To enter the programming
mode, place a jumper between the Push Button Enable (P. B. En.) Terminal and
the Common Terminal. Once the jumper is connected the programming buttons
are now activated. The Programming Mode consists of three selections; Rate
Multiplier, Decimal Point, and Timebase. There is a fourth display which is the
main display or run mode. Once programming is complete, the unit must be
returned to the main display before exiting the programming mode to obtain
normal operation.
INSTALLATION ENVIRONMENT
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
From the factory, the Ditak 9 is programmed with a fixed 1 second timebase
The unit should be installed in a location that does not exceed the maximum
The bezel should be cleaned only with a soft cloth and neutral soap product.
Note: The display changes on “PAR” or “SEL” push button release.

INSTALLATION
properly installed. The units are intended to be mounted into an enclosed
panel. A sponge rubber gasket, mounting clip, two screws, and nut fasteners
are provided to install and seal the unit in the panel cut-out.
The following procedure assures proper installation:
1. Cut panel opening to specified dimensions. Remove burrs and clean panel
2. Slide the panel gasket over the rear of the unit to the back of the bezel.
3. Slide nut fastener into slot on mounting clip and then insert mounting screw
4. Install Ditak unit through panel cut-out.
5. Slide mounting clip over rear of unit until clip is against back of panel. The
6. Alternately tighten each mounting screw to ensure uniform gasket pressure.
7. If the gasket is not adequately compressed and the mounting screws cannot
8. Repeat step #6 for tightening the mounting screws.
RATE MULTIPLIER
1.9999. See Programming Calculations to determine the calculated value. After
entering the programming mode, the least significant digit will be flashing. To
increment this digit, press the
over at 0. To move to the next digit press
by pressing
advance the meter to the Decimal Point selection.
DECIMAL POINT SELECTION
accomplished by repeatedly pressing
0.0000 when advancing to it from the Rate Multiplier selection. By pressing

TIMEBASE SELECTION
Programming Calculations to determine the calculated Rounded Time Base
(RTB) value. The value is changed by pressing
pressing
MAIN DISPLAY/RUN MODE
exit the Programming Mode and have the unit display properly. The push button
enable jumper can be removed after the Ditak 9 is returned to the main display.

NOT project through hole on clip.
mounting clip and Ditak housing have a latching feature to hold the unit in
place until tightened.
Note: Hold the Ditak front bezel in place when sliding the mounting clip
Visually inspect the gasket for proper seal. The gasket should be
compressed approximately 75 to 80% of its original thickness.

latched as close as possible to the panel.
The Ditak 9 has a Rate Multiplier (RM) selection range from 0.0001 to

The Ditak 9 has a Time Base selection range from 1 second to 7 seconds. See
Note: The position of the decimal point has no effect on this selection.
