KOIZUMI Digital Planimeter
Comcurve-8


D
Most Advanced Digital Curvi-meter (and Counter)
Employing Custom LSI Microcomputer

The COMCURVE-8 permits lines of any shape or any scale factor to be measured easily with simple operation. All you have to do is put the trace point of the equipment on the line to be measured and let it trace the line from the starting points to the end of the required length. The built-in custom LSI works out the line length based on the scale factor and uses the appropriate unit. Applicable units of length are the metric system (mm, cm, m and km), the yard-pound system (in, ft, yd and mile), the traditional Japanese system and nautical mile (n, m). Pressing the Shift Key and the CTM (Counter Mode) Key together allows the COMCURVE-8 to operate as a Counter.

Application :

* Measurement of line length or distance on maps, charts, road maps or orienteering maps.
* Measurement of required length of lines on wiring diagrams, plumbing drawings, metal mold design drawings or machine design drawings.
* Measurement of lines on drawings of ships, vehicles or aircraft.
* Measurement of dimensions of curves and paper patterns in dressmaking or handicraft.

 

Features :

* EXTENSIVE MEASURABILITY COVERING LINE LENGTH OF ANY SCALE FACTOR
Automatic unit conversion processing; and conversion of measured values from one scale factor or unit of length to another.
* A RICH ASSORTMENT OF UNITS OF LENGTH TO CHOOSE FROM
Measurement can be made in major units of length of the metric system the yard-pound system, the traditional Japanese system and in nautical mile.
* AVERAGING OF MEASURED VALUES
Results of drawing measurement performed several times can be averaged to minimize measuring error.
* ACCUMULATION OF MEASURED VALUES
Several measured values can be added together to obtain an accumulated total.
* MULTIPLE FUNCTIONS IN A LIGHT-WEIGHT AND COMPACT DESIGN
The COMCURVE-8 is designed compact enough to make it easy to carry and is provided with an automatic power-off function to eliminate power wastage.
* FREE MEASURING DIRECTION
The direction of tracing the line to be measured can be chosen as desired, that is, between left-to-right and right-to-left.
* FUNCTION AS A COUNTER
When operated in the counter mode, the COMCURVE-8 can count number up to 999, 999. Presetting the alarm allows an alarm signal to be heard when the required number has been counted.
