CHAPTER 1 TAKING MEASUREMENT 1-2 DONUTS PATTERN 1-1 NORMAL PATTERN first starting point second starting point starting point . Pu ta mark at a paint on the circumference of the drawing to be measured. This point will be the starting point of the measurement. Put another point on the internal circumference. This 1. Put a mark at a point on the circumference of the drawing to be measured. point will be the starting point for the internal circumference measurement.
6. Set the center of the tracer lens to match the internal circumference starting point as shown in the figure. Press key. The HOLD condition is released and "HOLD? disappears from display. 7. Keeping the tracer point of the tracer lens onto the internal circumference line, trace anticlockwise. 1-3 TWO DRAWINGS ARE SEPARATED 8, After going round, press | MEMO | yoy Measurement stops. A buzzer sounds, “MEMO” is displayed and the measured value is displayed.
Set the center of the tracer lens to match the starting point on the second drawing as shown in the figure. = o . Press HOLD | key. Measurement restarts “HOLD” disappears from display. ™ Keeping the tracer point of the tracer lens onto the circumference CHAPTER 2 SELECTION OF UNITS Units can be selected from the Metric system (cm, m, km} or English system {in, ft, acre) or the Japanese unit system (3%, FZ, BT} 1.
+ If due 16 sangs in unit system, the calculated value goes over and above) or under and below). The display will show as in the figure on the right. NOTE Using Auto power off, or even if the Key is pressed fo tum power off, units are stored in memory. Therefore, until new values are set, it is possible to continue usage as iris. On this instrument, calculation is based on 1 foot = 12 Inches. If you wish fo lake measurements in ha (hectares), first measure in km? and then divide by 100.
CAUTION « If the scale changes, measured values are re-calculated and displayed accordingly. (Example) If scale is 1:1 (A=1, B=1}, measured value is as shown on the figure to the right. 1f scale Is changed to 50:1 {A=50, B=50), measured value will change as shown on this figure. «if due to change In scale, the calculated value goes over (39993699 and above) or under and below). The display will show as in the figure on the right.
