Operating Instructions Measuring Range The measuring range is limited to 328’ (100m). If measuring at night or dusk and the target is in a dark area, the measuring range will increase. To increase the measurement range during daylight or if the target has poor reflection properties you can use a target plate. Target Surfaces Measuring errors can occur when taking measurements of colorless liquids (e.g. water) or dust free glass, styrofoam or similar semi-permeable surfaces. Aiming at high gloss surfaces may deflect the laser beam and lead to measurement errors. When measuring against non-reflective and dark surfaces the measuring time may increase. On and Off The On/Measure button turns the instrument and laser on. Press the CLEAR button for a few seconds to turn the instrument and laser off. The instrument switches off automatically after three minutes of inactivity. Clear Button This button cancels the last action and clears the display. Reference Level Setting The default reference setting is from the rear of the instrument. Press the REFERENCE button to take the selection from the top of the instrument. A special beep sounds whenever the reference setting is changed. After re-starting the instrument the reference returns automatically to the default setting.
Backlight Press the BACkLIghT/UNIT button to turn the backlight on and off. Distance Unit Setting Hold down the BACkLIghT/UNIT button for a few seconds to change the unit of measure. Continue to press the button to toggle between all units of measure. You can choose between m, ft, in. Single Distance Measurement Press the ON/MEASURE button to activate the laser. Press the button again to trigger the distance measurement. The measured value will be displayed immediately. Continuous (Tracking)/Max & Min Measurement The continuous measurement function (tracking) is used for the transferring of measurements. In continuous measurement mode, the meter can be moved to the target, whereby the measured value is updated approx. every 0.5 seconds. The corresponding max and min values are displayed dynamically in the first and second line. For example, the user can move from a wall to the required distance, while the actual distance can be read continuously. For continuous measurement, press the MAx/MIN button until the indicator for continuous measurements appears on the display. Press it again or press the ON/MEASURE button to stop the function. The meter resumes normal operation after 100 continuous measurements.
Addition/Subtraction Press the PLUS button to add the current measurement to the previous measurement. Press the ON/MEASURE button to add the second measured value; the result will automatically display. Press the MINUS button to subtract the current measurement from the previous measurement. Press the ON/MEASURE button for the result to be shown in the summary line and the previous measurement will be shown in the second line. Press the CLEAR button for the last step to be cancelled. Press the MAx/MIN button to return to single distance measurement mode. Area Measurement Press the AREA/VOLUME button once to enter Area Measurement mode. The icon will appear on the display to confirm you are in the correct mode. Press the ON/MEASURE button to take the first measurement (ie: length), press the ON/MEASURE button again to take the second measurement (ie: width). Then the area/surface is automatically calculated and displayed in the summary line on the display. The previous measurement will be shown in the second line. Volume Measurement Press the AREA/VOLUME button twice to enter Area Measurement mode. The icon will appear on the display to confirm you are in the correct mode. Press the ON/MEASURE button to take the first measurement (length), press the ON/MEASURE button again to take the second measurement (width), press the ON/MEASURE button again to take the third measurement (height). Then the volume is automatically calculated and displayed in the summary line on the display. The previous measurement will not be shown. reedinstruments INSTRUMENTS GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com...
Indirect Measurement This is used to determine a distance using two auxiliary measurements. Press the INDIRECT MEASUREMENT button once, the icon will appear on the display. Aim at the highest point and press the ON/MEASURE button to take the measurement. Holding the instrument as horizontal as possible press and hold the ON/MEASURE button to trigger continuous measurement, the horizontal line is measured and shown in the summary and secondary lines. Three Point Measurement Press the INDIRECT MEASUREMENT button twice, the icon will appear on the display. Aim at the highest point (1) and press the ON/MEASURE button to trigger the measurement. Holding the instrument as horizontal as possible press and hold the ON/MEASURE button to trigger continuous measurement and sweep the laser up and down over the ideal target point (2), press the ON/MEASURE button again to confirm the value. Aim at the lower point (3) and press the ON/MEASURE button to trigger the measurement. The results are shown in the summary and secondary lines at the same time. reedinstruments INSTRUMENTS GlobalTestSupply www.
Corrective Measure Calculation error Repeat procedure Received signal too weak/measurement Use target plate time too long/Distance >50m Received signal too strong Target too reflective (use target plate) Temperature too high Cool down instrument Temperature too low Warm up instrument Hardware error Switch meter on/off several times* Press the Storage button to view the previous 20 records (measurements or calculated results). Use the + and – buttons to navigate the records. Troubleshooting *If error persists contact REED Instruments at info@reedinstruments.com Care Do not immerse the instrument in water. Wipe off dirt with a damp, soft cloth. Do not use aggressive cleaning agents or solutions. Handle the instrument as you would a telescope or camera. Battery Replacement This instrument uses 2 “AAA” alkaline batteries. The batteries need to be replaced when the battery symbol flashes on the display. Remove the batteries before any long period of non-use to avoid the possibility of corrosion. Only use alkaline batteries. 1. Remove battery compartment cover. 2. Insert new batteries, respecting the correct polarity. 3. Close the battery compartment cover. reedinstruments INSTRUMENTS GlobalTestSupply www.
