4.3 Power On/Off
- To Power On: Press the MEAS button. The laser will activate.
- To Power Off: Long press the CLEAR button. The device will also automatically power off after 180 seconds of inactivity.
5. Operating Instructions
5.1 Basic Measurement
- Ensure the device is powered on.
- Point the laser beam at the target object.
- Press the MEAS button once. The measured distance will appear on the main display line.
5.2 Switching Units
Short press the Benchmark Switch / Unit Switch button to cycle through available units: meters (m), feet (ft), inches (in), and feet+inches (ft+in).

Figure 5.1: The Kiprim LD100 displaying measurements in various units. This image shows the device's ability to quickly switch between meters, feet, inches, and feet+inches, along with its accuracy of ±1/16 inch and storage capacity for up to 99 data sets.
5.3 Measurement Benchmark
Long press the Benchmark Switch / Unit Switch button to toggle between front-edge and rear-edge measurement benchmarks. An icon on the display will indicate the active benchmark.
5.4 Measurement Modes
Short press the Function Key to cycle through the following measurement modes:
- Single Measurement: Standard distance measurement.
- Continuous Measurement (Tracking): Displays real-time distance as you move the device. The maximum and minimum values are also shown.
- Area Calculation: Measure two sides (length and width) to calculate the area.
- Volume Calculation: Measure three sides (length, width, and height) to calculate the volume.
- Pythagorean Measurement (Indirect Measurement): Use the Pythagorean theorem to calculate inaccessible heights or distances. There are three types:
- Pythagorean-1: Calculates one side of a right triangle from two other measured sides.
- Pythagorean-2: Calculates height from two measurements to the top and one to the bottom, forming two right triangles.
- Pythagorean-3: Calculates height from three measurements, useful for complex scenarios.
