Setup

1. Charging the Battery

The REVASRI NK-1000 is equipped with a built-in lithium-ion battery. Before first use, fully charge the device.

1. Locate the USB charging port on the side of the rangefinder.
2. Connect the provided USB charging cable to the rangefinder and plug the other end into a standard USB power adapter (not included) or a computer USB port.
3. The charging indicator will illuminate. Once fully charged, the indicator will change or turn off (refer to device specific behavior).
4. A full charge typically takes a few hours.

2. Powering On/Off

• To power on, press the Power/Measurement button (usually the top button). The display will activate.
• The device will automatically shut down after a period of inactivity (e.g., 30 seconds) to conserve battery.

3. Adjusting Focus

Rotate the eyepiece to adjust the focus until the display and target appear clear and sharp.

4. Unit Selection (Meters/Yards)

The rangefinder allows switching between meters (M) and yards (Y). Consult your manual for the specific button combination to toggle units (often a long press of the Mode button or a combination of buttons).

Operating Modes

The REVASRI NK-1000 offers several modes to suit different measurement needs. Press the Mode button (usually the lower button) to cycle through the available modes.

1. Single Ranging (Distance Mode)

This is the standard mode for measuring the straight-line distance to a single target.

• Aim the crosshairs at your desired target.
• Press the Power/Measurement button once. The distance will be displayed instantly.

2. Scan Mode

Ideal for measuring multiple targets or moving objects continuously.

• Press and hold the Power/Measurement button.
• Pan the rangefinder across different targets. The distance will update continuously in real-time.

3. Golf Mode (Flag Lock)

Designed for golf, this mode helps to lock onto the flagstick, ignoring background objects.

• In Golf Mode, slowly scan the area around the flagstick.
• The device will identify and lock onto the closest target (the flagstick), often indicated by a vibration or a specific icon.
• The compensated distance (slope-adjusted) may also be displayed.

4. All-in-One Mode

This comprehensive mode displays multiple measurements simultaneously, including angle, height, horizontal distance, and straight-line distance.

• Select All-in-One Mode.
• Aim at the target and press the Measurement button.
• The display will show the angle, actual distance, horizontal distance, and vertical height to the target.

5. Speed Measurement Mode

Measures the speed of objects moving radially towards or away from the rangefinder.

• Select Speed Measurement Mode.
• Aim at the moving object and press the Measurement button. The speed will be displayed in KM/H.

6. Two-Point Altimeter Mode

This mode allows you to measure the height of an object by taking two measurements: one to the base and one to the top of the object.

• Select Two-Point Altimeter Mode.
• Measure the distance to the base of the object.
• Measure the distance to the top of the object. The device will calculate and display the height.

7. Memory Mode

Allows you to store and recall previous measurements. Consult your device's specific instructions for saving and retrieving data.

Maintenance

• Cleaning: Use a soft, clean cloth to wipe the lenses and body. For stubborn dirt, a slightly damp cloth can be used. Avoid abrasive materials or harsh chemicals.
• Storage: Store the rangefinder in its protective pouch in a cool, dry place when not in use. Avoid extreme temperatures and high humidity.
• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. If storing for extended periods, charge the battery to about 50% every few months.
