A Manual Torque Calibrator Machine is a device used to measure and calibrate torque wrenches and other torque tools manually, without digital assistance. It typically consists of a torque sensor, a display for torque readings, and a mechanism for applying torque to the tool being calibrated.

Here’s how it works:

• The torque tool is attached to the calibrator machine.
• A predetermined torque value is set manually using a torque adjustment mechanism.
• Torque is applied to the tool being calibrated using a manual handle or lever.
• The machine measures the torque applied and displays the reading on the torque display.
• The operator compares the displayed torque reading to the set value and makes adjustments to the torque tool if necessary.
• The process is repeated for various torque settings to ensure the tool’s accuracy across its range.
