1.1、AQBH digital torque meter is used for measurement, observation and tightening in a small range. The direct digital reading is easy to adjust to the appropriate torque value. The three-jaw keyless assembly is more suitable for clamping the tested product.In peak working mode, with automatic and manual storage100Group torque peak function,The time for automatically storing the torque peak value can be selected and set within the time range of (0.0 ~ 4) seconds;It can be directly connected to the computer through the USB data line for communication, and the stored data can be downloaded, viewed, analyzed, backed up, deleted, and printed out through the host computer software.

Second, the shape and structure

2.1 Basic structure

①Three claws

The three-jaw device can freely tighten and loosen with the tightening and loosening of the thread, and clamp the measured object.

②LCD Monitor:

The 4-digit LCD display includes power display, two working modes, preset value setting, torque unit, torque value, torque direction mark, and stored count value.

③USB communication interface

Connect a computer to transfer data, and connect a charger to charge the battery.

④Button panel

Key panel includesFive buttons

: Flip up to store data,Change settings.

: Enter data view mode, scroll down to store data,Switch the interface and change the settings.

:dataStore, switch or save when setting parameters.

: Switch the working mode.

: On / off, confirm zero,delete data.


Features include: mode settings、Numerical storage(automatic/Manual)、Data cleanup、data communication.

5.1. Operating instructions

P / C: boot and reset button

MD: Mode switch

MEN: data storage, setting window switching, pre data viewing

Up Arrow / Down Arrow: Change settings, flip up and down to store data

① Press and hold the power button for 2 seconds to power on and initialize the system

② In Track mode: data measurement is possible,

Data cannot be saved in current mode, long press MD key to enter setting mode

③Setting mode

1、Press MEN to switch, press MD to exit the setting mode and return to Track mode,UNIT unit setting press up and down key to switch

2、SAUT Peak mode automatically saves the data time setting, when set to 0, it is manually saved(Press the MEM keysave), Press the up and down keys to set the time MAX is 4 seconds,saveData can be saved100 groups。

3、ERASE Delete all data. The operation is to press the up key twice (the screen first displays YES and displays done) and the upper left corner of the digital tube is cleared (when the number becomes 000), all the data has been deleted

4、RESET to restore factory settings Same as above (ERASE)

5、OFFT Automatic shutdown time setting, press the up and down keys to set

④ Track mode short press MD to switch to pre mode, up and down keys to switch interface, MEN to view data

There are three interfaces in Pre mode:

1、HI:Saved MAX peak

2、LO: saved MIN peak

3、AVGE: save the average of all peaks

Remarks:The data viewed in pre mode without positive and negative directions is Absolute value

⑤ PEAK mode: In this mode, when the SAUT time period> 0, the measurement data will be automatically saved. The time period for saving can be set in the setting mode.

⑥ 在PEAK (In the peak value mode, press the down key to enter the peak data viewing interface, and use the down or up keys to view each set of data. P / C key can delete the current data. MD key to return to peak mode。
