Silverline Digital Range Measure 0.6-15m Operating Instructions

Specification

• The laser shall be used and maintained in accordance with the manufacturer's instructions
• Never aim the beam at any person, and particularly not into the eyes of any person or animal.
• Do not change the laser light assembly. Repairs must only be carried out by the laser manufacturer or an authorised agent. Do NOT exchange with a different type of laser

• Be sure to hold the Base Measurement Marker (7) against the surface from which you are taking a measurement
• Ensure there are no obstructions between the unit and the target point; this will cause a false readout
• The longer the distance being measured, the wider the ultrasonic signal pattern so more likely obstructions will affect the reading
• Do not attempt to measure through glass
• Measured surfaces should be smooth, flat, hard and of a similar material to get accurate measurements
• Sound absorbing surfaces such as foam, sponge and padding will prevent accurate measurements

1. Holding the Base Measurement Marker (7) against the wall from which you want to measure a distance, press the Read Key (6) to make the measurement. The projected laser beam, displaying as a red dot, will indicate the central point to which the measurement is made
2. The Digital Range Measure will calculate the distance from the base measurement marker to the projected laser point and display the distance in the Current Measurement (12) of the screen
3. Press the Metric/Imperial Key (5) to alternate between metric and imperial measurements
4. To reset the measure to zero, press the Plus/Equals Key (8) twice

• If either side of the Digital Range Measure is within 50cm of a hard surface, such as another wall, a false reading may be given
• The line between the Digital Range Measure and the projected red dot MUST be at 90° + -20° maximum, to the surface being measured
• If you hold down the Read Key (6) the Digital Range Measure will make continuous readings in length measurement mode

1. Having gained the first measurement, as described above, press the Plus/Equals Key (8). The Plus Icon (21) will be displayed above the original measurement. The original measurement will also be displayed in the Memory/Calculation Display (18) of the screen
2. Hold the Base Measurement Marker (7) against the wall from which you want to take the next measurement
3. Press the Read Key (6) to take the next measurement. The new measurement will be displayed in the Current Measurement (12) of the screen. If required you can re-take the measurement for the second figure
4. To add the two measurements together, press the Plus/Equals Key (8). The total measurement will be displayed in the Memory/Calculation Display (18) of the screen
5. To add further measurements, press the Read Key (6) to take the next measurement and then press the Plus/Equals Key (8) to add that value to the total measurement in the Memory/Calculation Display (18). This can be repeated to add further values

• If you press the plus/equals key twice without pressing the read key for a measurement in-between, both displayed values will be reset to zero
• The value in the memory/calculation display can be stored using the Memory Plus Key (9) which will be indicated by the Memory Icon (19). The value stored can be recalled by pressing the Recall Memory Key (4) and will be displayed in the memory/calculation display. Once the value is recalled it is removed from memory Press the memory plus key again to re-store it in memory if required
• Once the recalled value is displayed, pressing the plus/equals key will add the previous value displayed in the memory/calculation display and the recalled value together
• Although the display will turn off after some inactivity the display and memory values are stored and will be available next time the measure is turned back on

1. Press the Calculate Area Key (3) to change the mode to area calculation. The Area/ Volume Icon (20) will display on the screen. The 'L' (for length) will be flashing
2. Measure the length of the target area by pressing the Read Key (6). The Digital Range Measure will automatically store the length and display this measurement in the Current Measurement (12) of the screen
3. The 'W' (for width) in the Calculate Area icon on the screen will now be flashing
4. Measure the width of the area by pressing the read key
5. The Digital Range Measure will automatically calculate the area and display this in the Memory/Calculation Display (18) of the screen

• If you wish to re-measure, press the Calculate Area Key (3) again to reset the values to zero
• To review the measurements taken, press the Read Key (6) and it will cycle between the measurements taken for length and width
• To completely reset the measure to zero except for memory value: Hold down the Read Key (6) for 2 seconds after completing measuring. It will reset to initial length measuring mode

1. After the initial area has been calculated press the Memory Plus Key (9) to store the area value
2. Press the Calculate Area Key (3) and input 2 new measurements for length and width. The calculated area will be displayed
3. Press the Plus/Equals Key (8) and then the Recall Memory Key (4) and then the plus/equals key again to add the 2 area values together. The result will be displayed
4. If you wish to add further area figures, press the memory plus key to store the result displayed and then repeat from step 2

1. Press the Calculate Volume Key (10) to change the mode to volume calculation. The Area/Volume Icon (20) will display on the screen. The 'L' will be flashing
2. As with the area calculation the first measurement will be length (L), followed by width (W), followed by height (H)
3. Follow the process for taking these measurements as described in 'Measuring Distance'. Take care not to point the laser beam into your eyes when taking the height measurement
4. The Digital Range Measure will automatically calculate the volume of the space and display this in the Memory/Calculation Display (18) of the screen

• If you wish to re-measure, press the calculate volume key again to reset the values.
• To review the individual measurements taken, press the Read Key (6) and it will cycle between the measurements taken for length, width and height

1. After the initial volume has been calculated press the Memory Plus Key (9) to store the volume value
2. Press the Calculate Volume Key (10) and input new measurements for length, width and height. The calculated area will be displayed
3. Press the Plus/Equals Key (8) and then the Recall Memory Key (4) and then the plus/equals key again to add the 2 volume values together. The result will be displayed
4. If you wish to add further volume figures press the memory plus key to store the result displayed and then repeat from step 2

• While the temperature is displayed, press the metric/imperial key to switch between Fahrenheit and Celsius measurements
• To return directly to measurement readings, press the read ke
