To power on the device, press and hold the ON/OFF button. To power off, press and hold the ON/OFF button again until the display turns off.
Operating Instructions
1. Basic Measurement
Pull out the tape measure blade to the desired length. The real-time measurement will be displayed on the digital screen. Ensure the tape lock is engaged if you need to hold a specific measurement.

Image: The digital display provides clear, easy-to-read measurements, eliminating the need for squinting at small markings.
2. Unit Conversion
Short press the UNIT button to cycle through the available measurement units: "mm", "cm", "m", "ft", "in", and "ft'in". The selected unit will be indicated on the display.

Image: The UNIT button allows for quick switching between imperial and metric units, with examples of how measurements appear on the screen for each unit.
3. Zero Function (Tare)
The "Zero" function allows you to measure in segments. Press the ZERO button to reset the current measurement to zero, enabling you to start a new measurement from that point without retracting the tape.

Image: Demonstrates how the Zero function can be used to measure consecutive segments, with the display showing the current segment's length.
4. Center Finding Function
Press the 1/2 button to instantly display the midpoint of the extended tape length. This feature is useful for quickly finding the center of a board or space.

5. Inside/Outside Measurement Mode
The movable hook at the end of the tape automatically compensates for its own thickness. It retracts when pressed against a wall for inside measurements and extends when hooked on an edge for outside measurements, ensuring accurate readings.

Image: Shows the tape measure being used for both inside and outside measurements, highlighting the automatic compensation feature of the hook.
6. Area and Volume Measurement
The DT20 can calculate area and volume. After taking the necessary length, width, and height measurements using the tape, the device can compute and display the area or volume. Refer to the on-screen prompts or specific button combinations for these advanced functions.
