4. Setup

4.1 Battery Installation

The RISEPRO DL135N requires 2 AAA batteries (not included).

1. Locate the battery cover on the back of the device.
2. Slide the battery cover open.
3. Insert two AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Close the battery cover securely.

4.2 Initial Calibration

For optimal accuracy, it is recommended to perform a calibration upon first use or if you suspect inaccurate readings. Ensure the surface used for calibration is perfectly level.

1. Place the digital level on a flat, stable, and level surface.
2. Press the ON/OFF button to power on the device.
3. Press and hold the CAL button until 'CAL 1' appears on the display.
4. Release the CAL button. The display will flash 'CAL 1'.
5. Press the CAL button again to confirm the first calibration point. The display will show 'CAL 2'.
6. Rotate the level 180 degrees horizontally on the same flat surface.
7. Press the CAL button again to confirm the second calibration point. The display will show 'PASS' indicating successful calibration.

5. Operating Instructions

5.1 Power On/Off

Press the ON/OFF button once to turn the device on. Press and hold the ON/OFF button for approximately 3 seconds to turn it off.

5.2 Absolute Measurement Mode

In Absolute Measurement Mode, the device measures the angle relative to a true horizontal plane (0°). This is the default mode when the device is powered on.

Figure 5.1: Illustration of Absolute Measurement Mode (top) and Relative Measurement Mode (bottom).

5.3 Relative Measurement Mode

Relative Measurement Mode allows you to measure the angle difference between two surfaces. This is useful for comparing angles or setting a specific reference point.

1. Place the level on the first surface you wish to set as your reference (0°).
2. Press the REF button. The display will show '0.00°' and a 'REF' indicator, signifying that this position is now the relative zero.
3. Move the level to the second surface. The display will now show the angle difference relative to your set reference.
4. To exit Relative Measurement Mode, press the REF button again. The device will return to Absolute Measurement Mode.

5.4 Unit Conversion

The device can display measurements in four different units:

• Degrees (°)
• Percent (%)
• mm/m (millimeters per meter)
• IN/FT (inches per foot)

To switch between units, press the MODE button repeatedly until your desired unit is displayed.

5.5 Hold Function

To freeze the current reading on the display, press the HOLD button. The 'H' indicator will appear on the screen. Press the HOLD button again to release the reading and resume live measurement.

5.6 Audible Buzzer

The device features an audible buzzer that sounds when the level is at 0° (horizontal) or 90° (vertical). This is particularly useful when working in conditions where the display is not easily visible.

To toggle the buzzer on or off, press the Buzzer button (speaker icon).

5.7 Magnetic V-Groove Base

The integrated V-groove base with strong magnets allows the level to be securely attached to various metal surfaces, including pipes, conduits, and steel beams, for hands-free operation.
