OPERATION
TwinScan
®
3” GPH Instrument – Gallons Per Hour (LCD)
To ensure years of trouble free operation of your new TwinScan
® instrument,
please read all of these instructions carefully before beginning your installation.
1. Mounting Location
The TwinScan
® GPH instrument allows you to quickly monitor and compare port and starboard engine performance. The front faces
of all TwinScan® instruments are water-resistant and include a gasket to seal the instrument to the panel in which it is installed.
Caution: TwinScan
® instruments contain magnets that may affect your compass. Use care in choosing your mounting location.
2. Start-up Sequence and Normal Operation
The TwinScan
® GPH instrument performs a quick self-test each time it is powered up. The self-test verifies adequate power, good
ground connections, that the pointers are free, and the LCD display is working. During this test, the pointers will sweep smoothly
from zero to full scale and then back to zero. The LCD shows a series of numbers as detailed below (example values are used so
actual numbers may be different). Switches and configurations are shown on the LCD as: “0123456789AbCdEF”
“8.8.8.8” Checks LCD segments and backlighting.
“ 1.21” Software version number.
“F 3” The red (left) and black (right) switch settings.
“- - 34” Internal configuration (scale range, units, etc.)
“ ” Blank
“123.4” Current total gallons or total liters (normal operation).
After the self-test, the instrument goes into its normal operating mode. The needles indicate fuel flow in gallons (or liters) per hour
and the LCD shows the total gallons (or liters) consumed since the last reset.
3. Testing the Totalizer
The TwinScan GPH instrument has a non-volatile memory to track the total fuel consumed and therefore can only be reset by holding
the reset switch in the “RESET” position for approximately 15 seconds. You will notice the LCD totalizer blinking during the reset
mode—warning you that it is about to reset. After 10-15 seconds, the LCD will blink “E 0.0”. Release the switch to return to
normal operation.
4. Illumination
TwinScan
® instruments use a dual method of illumination to create a high contrast display making it easy to read at night without
affecting your night vision. The pointers are individually lighted so all the port pointers light when the port key switch is energized
and all the starboard pointers light when the starboard key switch is energized. “Light piping” directs the light from an incandescent
lamp across the dial face instead of bouncing it off the dial face and into your eyes.
5. Caring For Your Instrument
The front lens of your TwinScan
® instrument is made of hardened Lexan and is resistant to mild abrasion. Use mild soap and water to
clean. Never wipe with a dry cloth. This can scratch the lens and builds up static electricity attracting dust and dirt. Avoid solvents
such as acetone, benzene, and lacquer thinner as they attack the surface of the lens. Most window and kitchen cleaners contain at
least one of these solvents plus mild abrasives and should be avoided. Applying automobile or furniture wax covers minor scratches
on the lens and helps prevent further scratching.
