Addition and subtractionThe single-distance, area, volume, and indirect length can be added orsubtracted by the addition and subtraction functionto Take the first measurement..2. Press "<:_" key; the symbol + or - will show behind the battery indicator3 Take the second measurement4. The sum of the measurements will be displayed in the lowest row of thescreen, and the last measurements will be displayed at the same time in theupper row of the screen.5.. Follow the same method to make additional calculationsWorking with the tripod (available separately)The use of a tripod isparticularly helpful for greaterdistances. The measuringtool can be screwed onto acommercially available tripodusing the t/4" thread on thebottom side of the housing.t. Mount the tool to the tripod..2 Set the measuring referenceto the thread (Fig. 30).Fig. 30f"=g,bJJ.3 Start to take measurements.Error signalsThe following error signals may appear on the screen of your tool:Code ExplanationsErrO01 The reflected laser light is too intense.ErrO02 , Outo.!..range, The.measuring range for this tool is from t-100 feet. ...............ErrO03 The target provides poor reflection of the laser; change to anothertarget or cover the target with a piece of white paper.ErrO04 The temperature is too high; the optimum operating temperature is32 to 104°F (0 to 40°C).ErrO05 The temperature is too low; the optimum operating temperature is 32to 104°F (0 to 40°C).ErrO06 Low battery, a reminder to replace the batteries.ErrO07 Strong vibration, or the toot was moved quickly when measuring;always keep it steady when taking a measurement.ErrO08 Wrong input, the length of one side of the right triangle as measuredis longer than the hypotenuse; re-measure.48277 ManuaLRevised 09-0211 Page 19
