Working principle and usage

Hydraulic pressure

Unscrew the plug on the hydraulic output port and adjust the fine adjustment to the appropriate position (middle position). Close the pressure relief valve and gently operate the lever to allow the pressure guiding liquid to reach the two pressure output ports. Reinstall the standard gauge and the inspected gauge, operate the pressure rod, apply pressure to around 300Bar, use fine-tuning to adjust to the required pressure, and check point by point until the full range is reached. After inspection, open the pressure relief valve to reset the pressure to zero. After the pressure relief is completed, the inspected table and standard table can be removed.

Air pressure

Positive pressure: Unscrew the plug on the air pressure output port, install the standard gauge and the calibrated gauge, push the positive and negative pressure switching valve into the positive pressure position, close the pressure relief valve, rotate the micro adjustment counterclockwise to the farthest position, and use the pressure rod to apply the required pressure. If the required pressure is too high and the pressure of the inflation rod cannot be reached, you can use the micro adjustment to adjust it to your desired pressure. After calibrating and releasing the pressure, you can remove the calibrated gauge and the standard gauge.

Negative pressure: Install the standard gauge and the calibrated gauge, pull out the positive and negative pressure switch to the negative pressure position, rotate the micro adjustment counterclockwise to the maximum position, close the pressure relief valve, and use the pressure rod to apply pressure to your desired pressure. When the pressure is close to the desired value, use the micro adjustment to adjust to your desired pressure. After calibrating the gauge and releasing the pressure. Remove the inspected table and standard table.
