All conductors should meet voltage and current ratings for each terminal. Also cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power supplied to the unit (AC or DC) be protected by a fuse or circuit breaker. When wiring the unit, use the label to identify the wire position with the proper function. Strip the wire, leaving approximately 1/4" bare wire exposed (stranded wires should be tinned with solder). Insert the wire into the screw-clamp terminal and tighten the screw until the wire is clamped tightly. Each terminal can accept up to two #14 AWG wires.

The units are intended to be mounted into an enclosed Do NOT use solvents. Continuous exposure to direct sunlight may accelerate panel. A sponge rubber gasket, mounting clip, two screws, and nut fasteners the aging process of the bezel. 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 opening. 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 through nut on both sides of mounting clip. Tip of mounting screw should NOT project through hole on clip. 4. Install Ditak unit through panel cut-out. 5. Slide mounting clip over rear of unit until clip is against back of panel. The 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 into position. 6. Alternately tighten each mounting screw to ensure uniform gasket pressure. Visually inspect the gasket for proper seal. The gasket should be compressed approximately 75 to 80% of its original thickness. 7. If the gasket is not adequately compressed and the mounting screws cannot be tightened any further, loosen mounting screws and insure that the clip is latched as close as possible to the panel. 8. Repeat step #6 for tightening the mounting screws. RATE MULTIPLIER PROGRAMMING MENU The Ditak 9 has a Rate Multiplier (RM) selection range from 0.0001 to 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 SEL button. After the value 9, the digit will start over at 0. To move to the next digit press PAR and then that digit can be changed by pressing SEL. When reaching the most significant digit, pressing PAR will advance the meter to the Decimal Point selection. DECIMAL POINT SELECTION The selection of the decimal point position for the display (DDP) is Note: The display changes on “PAR” or “SEL” push button release. accomplished by repeatedly pressing SEL. This selection will always default to 0.0000 when advancing to it from the Rate Multiplier selection. By pressing PAR, the shown decimal point selection is entered and the Time base selection is shown. PROGRAMMING TIMEBASE SELECTION From the factory, the Ditak 9 is programmed with a fixed 1 second timebase The Ditak 9 has a Time Base selection range from 1 second to 7 seconds.
