Pre use status check

1. Whether the glass tube inside the ruler is intact, and whether the ruler fastening screws and nuts are complete.

2. Check whether each operation button and handwheel rotates flexibly and whether there is any jamming phenomenon.

3. Whether the complete supply is complete and intact.

installation and debugging

1. Place the host on a solid workbench, which should be flat and preferably covered with a layer of rubber sheet.

2. Install the ruler. When installing, place the suspension line of the scale hammer at the center of the small hole in the scale bracket, indicating that the scale is in a vertical position.

3. Rotate the water level valve handwheel to pull it out at a certain position, and then remove the handwheel. Use a syringe to inject distilled water into the hose until the water level of the water column is level with the "0" position on the scale. After stabilizing for 10 minutes, it can be used.

4. Connect the power supply, press the power switch, the power indicator light will turn on, and then press the air pump switch to check if it is sensitive.

5. Seal the air outlet and check the airtightness of the entire machine and the functionality of each component,

When the water column rises to 700mm, there should be no drop in the water column for one minute. everything

It can only be used after it is in good condition.

Instructions for use

1. Connect the air outlet with a rubber hose to the air inlet of the calibrated instrument.

2. Press the air pump switch to raise the water column to the desired position and release the air pump switch.
