Page 13 Calibration Check Before calibration of after repair: always perform a calibration check!! Depending of the result versus the specification of the laser, you must decide to calibrate or not. A calibration check can be done as described in the manual or via your test- environment (see procedure: Rotary calibration stands 14032017_ELR) Field calibration checks should be done frequently.
Page 14 DCE079 & DCE074 Compare total error to the allowable limits shown in the following table. Distance between walls Allowable error L = 15 m 3 mm L = 25 m 5 mm L = 50 m 10 mm - Level Calibration Check (Y-axis) Repeat the procedure above, but with the laser unit positioned so the Y-axis is pointed directly toward the walls.
Page 15 Different approach for DCE079 and DCE074 DCE079 DCE074...
Page 16 Prepare the laser for checking X and Y axis (only for the DCE079) Remove : Glass Cover Frame TX 10 Only for the pillar methode !
Page 17 Calibration X axis • Turn power on and let the instrument find its level , after the instrument is level (need about 1 minute), switch it off. • Press and hold Slope button then press Power button All the indicators will light up , indicating instrument is in calibration mode.
Page 18 Calibration X axis Incase of a DCE074 type 1, we have no X/Y indication LED: • Long press RPM button to select/switch between X and Y axis. => select X direction adjustment, 2 green LEDs lighting up and 2 red LEDs turning off, indicating we are currently X axis...
Page 19 Rotate the tool so that the X (I) is facing to the target.
Page 20 Calibration X axis Incase of a DCE074 type 2, we have no X/Y indication LED. How we start calibration mode? • Install the battery, long press the SLOPE BUTTON, meanwhile short press the POWER BUTTON. Hold the SLOPE BUTTON until POWER BUTTON released. All the indicators will light up , indicating instrument is in calibration mode.
Page 21 Press scan mode button to select dot mode. - Press the button so you can see the laser beam at the target wall. Adjust the dot on the target by turning the prism cover manually - Make your reference mark on the target. Rotate instrument 180 degrees with X (II) facing the same target.
Page 22 Calibration - Make your second mark on the target. Adjust the beam so that your laser become into tolerance of the spec by pressing After adjustment is complete , press and hold slop Button to save the setting. All the indicators will light up &...
Page 23 Incase of a DCE074, we have no buzzer sound indication • Here fore a small change made what indicates that we have saved our settings. • Visual you can check your savings by a Blink top laser beam for 3 times to indicate the calibration value’s been saved successfully.
Page 24 Calibration Y axis • Turn power on and let the instrument find its level , after the instrument is level (need about 1 minute), switch it off. • Press and hold Slope button then press Power button All the indicators will light up , indicating instrument is in calibration mode.
Page 25 Calibration Y axis Incase of a DCE074 type 1, we have no X/Y indication LED. • Long press RPM button to select/switch between X and Y axis. => select Y direction adjustment, 2 Red LEDs lighting up and 2 green LEDs turning off, indicating we are currently Y...
Page 26 Calibration Y axis Incase of a DCE074 type 2, we have no X/Y indication LED. • If you bring a type 2 unit into calibration, the unit will start automatically in X axes calibration! • To switch to Y axes calibration, follow these instructions: •...
Page 27 Rotate the tool so that the Y (I) is facing to the target.
Page 28 Press scan mode button to select dot mode. - Press the button so you can see the laser beam at the target wall. Adjust the dot on the target by turning the prism cover manually - Make your reference mark on the target. Rotate instrument 180 degrees with Y (II) facing the same target.
Page 29 - Make your second mark on the target. Adjust the beam so that your laser become in to tolerance of the spec by pressing After adjustment is complete , press and hold slop Button to save the setting. All the indicators will light up &...
Page 30 Incase of a DCE074, we have no buzzer sound indication • Here fore is a small change made what indicates that we have saved our settings. • Visual you can check your savings by a Blink top laser beam for 3 times to indicate the calibration value’s been saved successfully.
Page 31 Calibration with Ontrak system • Put your laser on the stand, X Axis facing the readers. • Turn power on and let the instrument find its level , after the instrument is level (need about 1 minute), switch it off. •...
Page 32 Rotate the tool so that the X (I) is facing to the target.
Page 33 • Make a readout of your first reference point. • Rotate instrument 180 degrees with X (II) facing the readers. • Make a readout of your second reference point. • If necessary (laser out of spec), make a correction.
Page 34 Calibration Adjust the beam so that your laser become into tolerance of the spec by pressing After adjustment is complete , press and hold slop Button to save the setting. All the indicators will light up & buzzer sounds indicating calibration is completed and setting are saved .
Page 35 After saving the changes, restart the unit, check the Y –axis for accuracy, via the same method (select Y) - Notes: - you should calibrate your instrument again if accuracy is out of spec. - Use your remote control instead of the onboard control panel.
Page 36 Calibration Z axis • Turn power on and let the instrument find its level , after the instrument is level (need about 1 minute), switch it off. • Press and hold Slope button then press Power button All the indicators will light up , indicating instrument is in calibration mode.
Page 37 • Follow procedure below by using a optical level • Adjust the beam so that your laser become in to tolerance of the spec by pressing • After adjustment is complete , press and hold slop Button to save the setting. All the indicators will light up &...
Page 38 After saving the changes, restart the unit, check the Y –axis for accuracy. - Note: you should calibrate your instrument again if accuracy is out of spec.

Page 40 Calibration of the Z axis Level the N24 with help of the Tribrach...
Page 41 The optical level should be placed between the tripod and the wall (at least 12m), ideal would be halfway, almost in line with the laser beam , but not where it blocks the beam.
Page 42 Tape a piece of paper across the top of the lasers unit rotary head, so the laser beam creates a dot on the paper. The head should be not spinning during this step...
Page 43 Adjust the elevation of the Optical Auto Level so that the horizontal cross -hair is lined up exactly on the center of the dot at the laser unit. DANGER: NEVER LOOK TROUGH AN OPTICAL LEVEL DIRECTLY AT A LASER SOURCE; SERIOUS EYE INJURY COULD RESULT !!
Page 44 Remove the paper from the laser rotary head, so that the beam can project a red dot on the far wall. Make a mark.
Page 45 Rotate the optical level around so that the laser can project a dot with the cross hair on the graph paper mounted on the wall. Measure the difference between first mark and de horizontal cross hair. This will give you the amount of calibration error of the laser unit’s Z axis.
Page 46 Measure how far the centre of the red dot is above or below the cross-hair. This is the amount of calibration error of the lasers Z axis.
