Do you know how to check the flow rate of the laser circuit with the T-803A temperature controller? First, turn on the chiller, and press the pump start button. The PUMP indicator on means the water pump activates. Press the “down” key to check the operational parameter of the chiller. Then press the “up” key to find the CH3 item. The lower window will display the flow rate value. Got it? If not, please follow me and send a message~
