UNIT SETUP

Horizontal Mode
You may set your instrument unit up on a tripod, hang it up on a wall with a wall mount (NUCB05, sold separately) or simply set it on a stable surface.
Vertical Mode
With the vertical bracket provided (NUCB05, sold separately) set the instrument on a tripod or stable surface. Instrument should be set approximately level within ±6°(±1°).

OPERATION

Automatic leveling

Short press the Power Button to power on the unit. The unit will level automatically. The Power Indicator will be on.

In horizontal mode:
The unit will activate the laser beam and start rotating after self-leveling.

In vertical mode:
The unit will activate a laser point without rotating and enter slope mode after self-leveling

Slope

In horizontal mode:

1. Adjust the unit to point the X/Y direction (find the X/Y marked on the top of the unit) towards the target.
2. Power on the unit.
3. Short press the Working Mode Switching Button to switch the unit to Slope Mode.
4. Short press slope axis the Slope Axis Switching Button to switch the
5. Press the Up/ Increase/ CCW Button to increase the slope and the Down/ Decrease/ CW Button to decrease.
6. Short press the Working Mode Switching Button to switch the unit back to Normal Leveling Mode.

In vertical mode:

1. Adjust the unit to point the X/Y direction (find the X/Y marked on the top of the unit) towards the target.
2. Power on the unit.
3. Wait for the unit to level itself automatically and the unit will enter Slope Mode by default (the default slope axis will be X.)
4. Short press the Up/ Increase/ CCW Button or Down/Decrease/ CW Button to start rotating.
5. Short press the Working Mode Switching Button to switch the unit back to Normal Levelling Mode

HI Mode and HI Alert
The unit will enter HI Mode after 30 seconds of no button operation once it has automatically leveled.
In HI Mode, if the unit detects that it is no longer level, it will generate the HI Alert.
To clear the HI Alert, power the unit off and back on again.

Remote Control

Infrared:
An infrared remote comes with the rotary laser as an accessory. Users can control the unit with the remote instead of directly operating the keypad on the rotary laser itself.
Bluetooth and Detector:
NRL900HT-G and NRL900HT-R support remote control through Bluetooth or the detector.
Users can use NWi Smart Laser App to connect to and control the rotary laser directly within a distance of 100ft.
Users can use the same app to connect to the detector, while the detector connects to the rotary laser. In this way, the communication distance can be extended to a maximum of 1000ft.

CHECKING CALIBRATION

Although every unit has been calibrated in the factory before shipping, it is also the user’s responsibility to check the accuracy of the units before use to avoid costly mistakes.

Checking Horizontal Accuracy

1. Set up the unit at around 98ft(-3ft) away from the wall (or a rod), with the X direction (check the mark on the top of the unit) aiming toward the wall.
2. Power on the unit and wait until the unit is leveled. Mark the current laser line on the wall and name it with h1. If it’s difficult to see the laser line, the detector can help.
3. Rotate the unit 180° so the -X direction is aiming towards the wall.
4. Wait until the unit is leveled. Find the laser line on the wall and mark it as h2.
5. The error of the X direction will be h1-h2 and it is required to be within +/- 1/16in.
6. Check the Y axis through the same method.
7. If the error of any axis exceeds the criteria, the unit needs to be sent to an authorized service center and calibrated.

Checking Vertical Accuracy

1. Set up the instrument between 2 walls (or 2 grade rods) about 30m from each other. Set it closer to one wall than the other as shown below ( Figure 2 ).
2. Lay down the instrument as shown. Press the Power Button and the instrument will find its level position. Mark the laser position on the wall as hA and hB .
3. Then re-install the unit to close to the other wall as shown below
   ( Figure 3) , repeat step 2 and mark the points as hA1 and hB1. Calcu-late Δ 1=hA – hB , Δ2= hA1 – hB1. The difference between Δ1 and Δ2 should be within +/- 1/8in .
