3. Setup

3.1 Initial Adjustment

Upon first use, or if the view is unclear, rotate the eyepiece knob (3) to adjust the focus until the view is sharp. If you wear eyeglasses, adjust the view before using the device.

3.2 Charging

The REVASRI NK-1000 is equipped with a built-in rechargeable lithium battery and supports Type-C charging. Connect a Type-C cable to the USB port on the device to charge.

3.3 Unit Switching (M/Yard)

The device supports two units: Yard (Y) and Meter (M). The default unit is Yard (Y).

1. Long press the Power button (1) and Mode button (2) simultaneously for 3-5 seconds.
2. The viewing unit displayed through the eyepiece will switch between M and Y.

3.4 Angle Calibration

Calibrate the device if the angle measurement is inaccurate. Perform calibration on a horizontal platform or a tripod with an adjusted horizontal angle.

1. Power on the device.
2. Press the Mode button (2) to switch to ranging mode.
3. Long press the Mode button (2).
4. The angle display will flash.
5. Release the Mode button (2).
6. Long press the Mode button (2) again to calibrate.
7. The angle will display 0°0 the next time you measure under horizontal status.

4. Operating Modes

The REVASRI NK-1000 offers six different measurement modes. Press the Mode button (2) to cycle through the modes.

4.1 Mode 1: Ranging Mode (Measuring Distance)

Measures the straight-line distance from the rangefinder to the target.

1. Power on the device.
2. Aim at the target.
3. Press the Power button (1) to measure.
4. The distance (M) will be displayed on the screen.

4.2 Mode 2: All-in-one Mode

Measures the straight-line distance, angle, vertical distance, and horizontal distance simultaneously.

1. Power on the device.
2. Press the Mode button (2) to switch to All-in-one Mode.
3. Aim at the target.
4. Press the Power button (1) to measure.
5. The data (angle, straight-line distance, vertical distance, horizontal distance) will be displayed.

4.3 Mode 3: Scanning Mode

Provides continuous measurement of straight-line distance, angle, vertical distance, and horizontal distance as you scan across multiple targets.

1. Power on the device.
2. Press the Mode button (2) to switch to Scanning Mode.
3. Aim at the target.
4. Long press the Power button (1) to enter continuous measurement.
5. The data will continuously update as you move the rangefinder.

4.4 Mode 4: Two Point Height Measurement Mode

Measures the vertical height difference between two targets.

1. Power on the device.
2. Press the Mode button (2) to switch to Two Point Height Measurement Mode.
3. Aim at the first target (e.g., the bottom of an object) and press the Power button (1) to measure.
4. Aim at the second target (e.g., the top of the same object) and press the Power button (1) to measure.
5. The slope distance, horizontal distance to the second point, and the height difference between the two points will be displayed.

4.5 Mode 5: Speed Measurement Mode

Measures the speed of a target object moving in radial motion (towards or away from the rangefinder). Note: The speed of a target moving in parallel cannot be measured as the distance from the rangefinder to the target does not change significantly.

1. Power on the device.
2. Press the Mode button (2) to switch to Speed Mode.
3. Aim at the moving target.
4. Press the Power button (1). The laser indicator will flash, and continuous measurement will begin.
5. The speed of the target object (in Km/h) will be displayed.

4.6 Mode 6: Golf Slope Compensation Mode (with Flagpole Locking)

This mode is designed for golfers, providing slope-compensated distances and flagpole locking.

1. Power on the device.
2. Press the Mode button (2) to switch to Golf Mode.
3. Select the target object (e.g., flagpole) and aim the target indicator at it.
4. To use Flagpole Locking: Long press the Power button (1) to enter scanning mode (aim at the slope/background behind the flagpole). Move the target indicator from the background to the flagpole slowly. Once the flagpole is locked successfully, it will flash, and the suggested hitting distance will be displayed.
5. Alternatively, you can aim directly at the flag and short press the Power button (1) to measure without using the flag lock function.

Slope Compensation:

• When the slope is positive (uphill), the play distance will be greater than the sight distance.
• When the slope is negative (downhill), the play distance will be less than the sight distance.

4.7 Data Storage Function

The device can store previous measurement data.

1. Power on the device.
2. Press the Mode button (2) to switch to the storage function; the display will show "Lb".
3. Press the Power button (1) continuously to view the previous 10 sets of measurement data.

5. Maintenance

• Do not put the device out of the storage temperature range of -20°C to 50°C.
• Avoid direct sunlight on the eyepiece to prevent damaging the eyepiece display or internal components.
• Always store the device in its protective case when not in use.
• Use standard batteries and charge the device correctly.

6. Troubleshooting

If you encounter issues with your REVASRI NK-1000 Rangefinder, please refer to the following common problems and solutions:

• Unclear View: Rotate the eyepiece knob to adjust the focus until the view is clear.
• Inaccurate Measurements (Rainy/Foggy Conditions): Water droplets in the air can interrupt laser transmission. Avoid using the rangefinder on rainy or foggy days, as measurements may be inaccurate.
• Inaccurate Measurements (Surface Reflection): Some surfaces do not reflect laser as well as others. The maximum range to these surfaces may vary, leading to inaccurate readings.
• Measurements Less Than 5 Yards: The minimum effective range is 5 yards. Avoid measuring in small rooms or at very close distances, as you may not get readings less than 5 yards.
• No Readings in Storage Mode: Measurements cannot be taken while in storage mode. Press the Mode button to switch to another measurement mode for normal operation.
• Device Powers Off Automatically: The device will power off if there is no operation for 30 seconds to conserve battery. This is normal behavior.
• No Readings Through Glass: Glass can reflect the laser beam and affect measurement results. Do not measure through glass.
• Low Light Visibility: In low-light conditions at night, additional lighting may be required to view the readings, as the eyepiece display is not illuminated.

7. User Tips

• For long-distance measurements, especially beyond 100 meters, be aware that environmental factors can slightly affect accuracy.
• Ensure the eyepiece is properly focused for the clearest view before taking measurements.
• Keep the device charged using its convenient Type-C port for uninterrupted use.
