【product】：Sensor structure :Inner sensorAccuracy:±1%Power : 2 AAA batteries 1.5V(NOt include)Working temperature :5-35Transport temperature :-10-60Relative humidity :15%-80%RHWorking conditions :No vibration source around and no corrosive environment.Dimensions :124*60*31(mm)Net weight :400g【feature】：1. Real-time modeTurn on the measurement interface, the system defaults to real-time measurement mode, and no mode is displayed on the screen.In this mode, the displayed measured value will change along with the load.2. Peak modePress the "PEAK" key, and the word "P" displayed on the screen is the peak mode. In this mode, the displayed measurement value is the maximum value. (When measuring again, if the measured value is lower than the previous maximum value, the displayed measured value will not change;if the measured value is higher than the previous maximum value, the displayed measured value will update and change.)3. First peak modePress the "PEAK" key, and the words "P" and "T" are displayed on the screen at the same time is the first peak mode.In this mode, the instrument only displays the first peak value measured in a period of time, and the measured value will not be displayed again. If there is a change, press the "ZERO" key to clear it before testing again.4 .Setting function of gravity acceleration----User can input at your option the accurate value of gravity acceleration at the using place so as to make the testing and unit conversion be more accurate.5 .Minimum force value shielding function: the data within the set minimum range can be shielded;6 .Automatic shutdown function: The automatic shutdown time can be set, and the automatic shutdown can achieve a point saving effect when there is no operation for a long time.【Pull Push 2-500 N】：1.
