4. Nastavení
4.1 Instalace baterie
The digital torque meter requires 3 AAA batteries (not included) for operation.
- Najděte přihrádku na baterie na zadní straně zařízení.
- Open the battery cover using the provided screwdriver if necessary.
- Vložte 3 baterie typu AAA a dbejte na správnou polaritu (+/-) vyznačenou uvnitř přihrádky.
- Pevně zavřete kryt baterie.
4.2 Attaching to a Ratchet Wrench
The digital torque meter is designed to be used in conjunction with a standard ratchet wrench. It effectively converts your existing wrench into a digital torque wrench.
- Select a ratchet wrench with a square drive size compatible with your torque meter model (e.g., 1/4", 3/8", or 1/2").
- Insert the square drive of the torque meter into the square hole of the ratchet wrench.
- Ensure the connection is secure. If necessary, use appropriate adapters (e.g., 1/2" to 3/8" adapter) for compatibility.
Note: The ratchet wrench and any necessary adapters are typically purchased separately.
5. Návod k obsluze
5.1 Zapnutí/vypnutí
- Pro zapnutí stiskněte C tlačítko.
- Chcete-li přístroj vypnout, stiskněte a podržte tlačítko C button for a few seconds, or the device will automatically shut down after 60 seconds of inactivity.
5.2 Selecting Working Mode (Trace/Peak)
The torque meter offers two working modes:
- Trace (T) Mode: Displays real-time torque values as they are applied.
- Peak (P) Mode: Captures and displays the maximum torque value achieved during a measurement.
Chcete-li přepínat mezi režimy, stiskněte tlačítko PT tlačítko.
5.3 Selecting Torque Units
The device supports four common torque units:
- kgf.cm
- N.m (Newton-meter)
- Ibf.ft (Pound-force foot)
- Ibf.in (Pound-force inch)
To cycle through the available units, press the U tlačítko.
5.4 Setting Target Torque and Alarm
You can set a target torque value, and the device will alert you when it's reached.
- While in a measurement mode, use the ▲ (Přírůstek) a ▼ (Decrement) keys to adjust the preset target torque value.
- As you apply torque, when the measured value reaches the preset target, the buzzer will sound continuously, and the red LED light will illuminate.
5.5 Reading Torque Values
The large digital display shows the current or peak torque value, depending on the selected mode.
The backlight function ensures readability even in low-light conditions.
5.6 úložiště dat
The device can store up to 999 sets of measurement data. Press the M button to access and review stored data. Refer to the on-screen prompts for navigation.

- Vyhněte se dopadu: Protect the device from drops and strong impacts, as this can affect its accuracy and functionality.
7. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Zařízení se nezapne. | Vybité nebo nesprávně vložené baterie. | Zkontrolujte polaritu baterií. Vyměňte za nové baterie AAA. |
| Nepřesné údaje. | Device not properly calibrated (unlikely for new device) or damaged. | Ensure proper connection to the wrench. If issues persist, contact customer support. |
| Alarm not sounding/lighting up. | Target torque not set or reached. | Verify the target torque setting. Ensure the applied torque exceeds the set value. |
8. Uživatelské tipy
- Always ensure the digital torque meter is securely attached to your ratchet wrench before use.
- For critical applications, perform a test measurement on a known fastener to confirm accuracy.
- When setting target torque, consider the material and specifications of the fastener to avoid over-tightening or damage.
- The device is suitable for a wide range of applications, but always use the correct model and torque range for the task at hand.
