The high-precision series digital torque screwdriver is a product carefully designed for the assembly and torque detection of small torque fasteners in the precision manufacturing industry. It has precise torque display, sound and light alarm prompt function, and three working modes (tracking, peak, preset) can be switched freely. In peak working mode, it has the function of automatically and manually storing 500 sets of torque peak values. The time for automatically storing torque peak values can be set by the user within a time range of (0.5-4) seconds; It can be directly connected to a computer through a USB data cable for communication, and the stored data can be downloaded, viewed, analyzed, backed up, deleted, and printed out through the upper computer software. This product is widely used in industries such as instruments and meters, household appliances, electromechanical equipment, automobiles, motorcycles, etc. It is a high-end tool that ensures precise tightening and connection of bolts and nuts with small torque and small torque.

A Basic Structure:

Adjust the working direction of the digital torque screwdriver with the L111L reversing wheel. Rotate the reversing wheel of the digital torque screwdriver to the "L" position for counterclockwise working direction, and to the "R" position for clockwise working direction; Rotate to the "0" position for clockwise and counterclockwise working directions. The 4-digit LCD display includes battery level display, three working modes, torque short position, group torque value, torque direction marker count value, storage value, and storage value sequence number. The stored data can be transferred to the computer through the USB port, and data processing can be achieved with the software produced by the manufacturer. The software interface can be found on the last page. Using the CD provided by the manufacturer, install the communication components on the computer, then use the data to disconnect the digital torque screwdriver from the computer. Double click the software icon to open the software, which prompts a successful connection. Follow the instructions in the software manual to read and store data. (5) Set the working parameters in unit i → Auto save time → Accuracy judgment → Clear data → Restore factory settings → Real time clock settings (UUUU1, 2, 3 → SAVE0.8 → AUSb1-3 → EEEE → SSSS → Real time clock). In preset mode, set the working parameters for a long time, control [MEM] to switch and save, and adjust by pressing the [/,] keys 1-inch setting (UUUU0, 1, 2, 3), 0: N.m, 1: lbf. ft, 2: lbf. in, 3: kgf. cm. : a Automatic save time lSAVE 0_8) LCD displays SAVE as the white dynamic save time setting, 0 as manual save, 1-8 as 0.5-4s respectively. ③ New judgment accuracy (AUSb1-3) LCD displays AUSb as the judgment accuracy setting, 1-3 as ± 1%, _3% 4: Clear data (EEEE1 LCD displays EEEE as the clear data setting, Ll as confirmation to clear data, "indicating not to clear data. ⑤ Restore factory value setting (SSSS1LCD displays SSSS as the second return factory value setting, Ll as confirmation to restore factory value," indicating not to restore factory value. ⑥ Real time clock 1_year, _2month, 3_ Day, 4_ hour, 5_ minute.

In tracking mode A, press and hold the four keys for 2 seconds to turn on the device.

Press the m key to switch the working mode to the preset torque value, press the [1] button to switch the selection position, press the a button to cycle down, and press the [^] button to cycle i without adding. The preset range is 10% -100% of the full scale. C applies force to complete one operation. E works in peak mode A technique [Pl'll]. Press and hold for 2 seconds [P/(l) to turn on the device. Press the m key to switch the working mode to the preset torque value, press the field key to switch the selection position, press the a key to cycle and decrease, and press the [^] key to cycle and increase. The preset range is 10% -10%. Press [Mii] to confirm the settings and switch to peak mode.

To ensure the accuracy of the digital torque screwdriver, please make sure to reset it to zero by pressing [P/(l) when it is not under force before use (parameter setting: preset: group value 0.5N. m, report prompt 2%). When the torque value loaded by the digital torque screwdriver reaches 90% of the preset group torque value (i.e. 0.495N. m), the alarm light starts flashing yellow and flashes well (flashing well, frequency increases with the increase of the cutting group torque value). When the loaded torque value reaches the qualified range of the torque value to be set (0.5 ± 0.5 x1%=0.495-0.505N. m), the yellow light of the alarm light is visible for a long time, accompanied by an alarm sound of "ringing"; If the cutting torque value exceeds the qualified range of the preset torque value (i.e.>0.050N. m), the alarm light will continue to emit a red light with a continuous "beep" sound. (Note: When storing torque values within the qualified range, the alarm light flashes yellow; when storing torque values within the unqualified range, the alarm light flashes red)

1. Connect the USB interface to the computer to transfer data, and connect the charger to charge the battery. The facial mask switch includes five buttons [P/ll, [MEM], [Mlil, [v:], [^] and one alarm light. '141 The switch key of the facial mask is displayed: key n turns up to store data Pre set value addition. Store the peak torque value of the entire field, switch and save when setting parameters. Switch the working mode with the [Mil] key. Enter the data viewing mode, scroll down to store data, decrease preset values, and turn on or off the background difference in tracking mode. Turn on/off the entire [p7i] and confirm the zero position Delete data. The alarm light is available in two colors: yellow and red. When the torque value reaches the set torque value, the alarm light is on, indicating to the operator that the set torque value has been reached. The back cover of the L151 battery can be opened with a flathead screwdriver for battery replacement. The battery can be installed with the negative pole facing inward and the positive pole facing outward.
