4. Seadistamine

4.1 Aku paigaldamine

1. Locate the battery compartment cap at the end of the handle.
2. Unscrew or unclip the cap to open the compartment.
3. Insert the required batteries (typically AA, refer to packaging for exact type) ensuring correct polarity (+/-).
4. Replace the compartment cap and secure it.

4.2 Esialgne kalibreerimine

For optimal accuracy, ensure the wrench is calibrated before first use and periodically thereafter. Place the wrench on a flat, level surface. Press and hold the 'C' (Calibration) button until the display shows '0000' or a similar calibration indicator. This process zeros the sensor, preparing it for accurate measurements.

5. Kasutusjuhised

5.1 Toide sisse/välja

• To power on, press the power button (usually marked with a power symbol or 'C'). The display will light up.
• To power off, press and hold the power button until the display turns off. The wrench may also have an auto-shutoff feature after a period of inactivity.

5.2 Ühiku valik

Press the 'U/S' (Unit/Setting) button to cycle through available measurement units: ft./lb., in./lb., Nm, and degrees (for angle measurement). Select the desired unit for your application.

5.3 Setting Target Torque/Angle

• Use the arrow buttons (up/down) on the control panel to adjust the target torque value or angle.
• The display will show the set value.

5.4 Pöördemomendi rakendamine

1. Attach the appropriate socket to the 1/2-inch drive head.
2. Asetage pistik kinnitusdetailile.
3. Apply steady, smooth force to the handle. The digital display will show the real-time torque being applied.
4. As you approach the target torque, the wrench will provide audible beeps and visual indicators (e.g., green LED) to alert you.
5. Once the target torque is reached, the wrench will emit a continuous tone and/or a red LED will illuminate, indicating that you should stop applying force. This 'click style' feedback helps prevent over-tightening.

5.5 Clockwise/Counter-clockwise Usage

The wrench is designed to measure torque in both clockwise and counter-clockwise directions. Ensure the ratchet direction switch on the drive head is set correctly for your application.

6. Hooldus

• Puhastamine: Wipe the wrench with a clean, dry cloth after each use. Do not use harsh chemicals or abrasive cleaners.
• Hoiustamine: Store the torque wrench in its original durable clear case in a dry, temperature-controlled environment. Remove batteries if storing for extended periods to prevent leakage.
• Kalibreerimine: Digital torque wrenches should be recalibrated periodically by a qualified service center to maintain accuracy. Refer to the manufacturer's recommendations for calibration intervals.
