SAVING A MEASUREMENT 1. Follow the steps under “Taking a Measurement” to measure a dimension. 2. Press STORE then a memory key (M1, M2, M3).M and the number of the memory location you choose (1,2 or 3)appear and the measurer stores the reading in that memory location. 3. If necessary, repeat steps 1 and 2 to save up to three measurements. 4. To display a measurement stored in a memory location , press that memory key (M1,M2,M3). The measurement stored in that memory location appears. 5. To delete a measurement stored in a memory location, simply store a new one in its place. To clear all stored measurements, hold down ALL MEMORY CLEAR for about 3 seconds, the 1. measurer beeps and M and the number of the memory location you chose (1,2 or 3) disappears. Note: Data of AREA or VOLUME can not be saved. CALCULATING VOLUME To find the volume of a room, Measure the height. Width and the length of the room and store each measurement in a different memory location (see “Saving a Measurement”). Then press VOLUME, The volume calculation result appear. CALCULATION AREA Follow these steps to find the area of any two stored measurements 1. Measure the width and length of a room and store the measurements in M1 and M2 (see “ Saving a Measurement”). Press AREA, M1 and M2, the area calculation appear. ADDING/SUBSTRACTING STORED
MEASUREMENTS 1. Measure any two dimension of a room and store the measurements in memory locations 1 and 2(see ”Saving a Measurement”) 2. Press ALL MEMORY CLEAR. 3. Press M1, +, M2, then + to add the measurements, or M1, -, M2, then - to subtract them. The value of the calculation appears. 4. To clear the display and do another measurement, press ALL MEMORY CLEAR. USING LASER To have a laser pointer, press LASER. The laser pointer disappears automatically after about five seconds SPECIFICATIONS Power 1x9V Unit of measurement Feet or Meters Accuracy 0.5%+1 digit (2~60ft) Working Frequency 40kHz Working Temperature 32°Fto 109.4°F(0°C to 43°C) Range 2 to 60 ft (0.50 to 18.288m) Specifications are typical; individual units might vary.
