ADDITION (W/O USING MEM):
- Press “Read” for measurement.
- Press”+/=“ to enter the addition mode. A “+” icon will appear on LCD.
- Press and hold “Read” again for second measurement.
- Press”+/=” again the sum is shown on the bottom.
ADDITION (USING MEM):
- Press “MEM INPUT” to save the desired measurement for the addition.
- Press “Read” for new measurement.
- After getting the new measurement, press “+/=” to enter the addition mode. A “+” icon will appear on LCD.
- Press “MEM Recall” to recall previous measurement for the addition. The “MEM” icon will disappear and the stored memory will be automatically cleared.
- Press “+/=” again, the sum is shown on the bottom.
AREA:
- Press “LW” to enter Area mode for calculation of a room area.
- “L” will blink showing which measurement you will be taking. Press “Read” to take “L” measurement that is displayed on upper portion of screen. (Step1)
- “W” will blink showing the next measurement to take. Press “Read” to take “W” measurement that is displayed on upper portion of screen.(Step2).
- Then the Area is automatically displayed on the lower portion of the screen.
- Pressing the “Read” key again will toggle back and forth between the “L” and “W” measurements.
- To start another Area mode, press”LW” key again.
- To leave the Area mode to make a single measurement, press and hold the “Read” key for about 2 seconds.
ADDITION OF AREAS UNDER AREA MODE:
- Press “MEM INPUT” to save the calculated area.
- Press “LW” to measure new area (Follow Step1&2 under the Area section).
- After getting the desired area, press “+/=” to enter the addition mode. A “+” icon would appear on LCD.
- Press “MEM RECALL” to recall the first calculated area for the addition. The “MEM” icon will disappear and the stored memory will be automatically cleared.
- Press “+/=” again, the sum of both areas is shown on bottom.
IMPORTANT NOTE:
Before press and hold “READ” to leave the Area mode, the measurement of “L” and “W” must be completed first.
VOLUME:
- Press “LWH” to enter Volume mode for calculation of a room volume.
- “L” will blink showing which measurement you will be taking. Press “Read” to take “L” measurement that is displayed on upper portion of screen.(Step1)
- “W” will blink showing the next measurement to take. Press “Read” to take “W” measurement that is displayed on upper portion of screen. (Step2)
- “H” will blink showing the next measurement to take. Press “Read” to take “H” measurement that displayed on upper portion of screen. (Step3)
- Then the volume is automatically displayed on the lower portion of the screen.
- Pressing the “Read” key again will toggle back and forth between the “L”, “W” and “H” measurements.
- To start another volume mode, press “LWH” key again.
- To leave the volume mode to make a single measurement, press and hold the “Read” key for about 2 seconds.
ADDITION OF VOLUMES UNDER VOLUMEMODE:
- Press “MEM INPUT” to save to the calculated volume.
- Press “LWH” to measure new volume (Follow Step1 to 3 under the volume section).
- After getting the calculated volume, press “+/=” to enter the addition mode. A “+” icon would appear on LCD.
- Press “MEM RECALL” to recall the first calculated volume for the addition. The “MEM” icon will disappear and the stored memory will be automatically cleared.
- Press “+/=” again, the sum of both volumes is shown on bottom.
IMPORTANT NOTE:
Before press and hold “Read” to leave the volume mode, the measurement of “L”, “W” and “H” must be completed first
MEM INPUT:
Store a length, area or volume into memory. And the “MEM” icon will appear.
MEM RECALL:
Displays the last stored memory. And the “MEM” icon will be automatically cleared.
FT/M:
Change the measurement unit for length, area and volume from ft./in. to metric.
CARE AND HANDLING:
- The Laser Tape is a precision instrument which must be handled with care.
- Avoid shock, vibrations and extreme heat.
