How to troubleshoot a Hach Measuring Instruments when the display doesn't light up and the pump motor isn't operating?
If the display does not light up and the pump motor isn't working on your Hach Measuring Instruments, the issue could be due to a lack of operating power. Check the power switch position, fuses, and power cord connections.
What to do if my Hach CL17 displays an 'EE Error'?
If your Hach Measuring Instruments shows an 'EE Error', it means the device is unable to write to the EE ROM. Try pressing the EXIT key to restart the instrument. If the problem continues, the main circuit board may need replacement.
What to do if my Hach Measuring Instruments shows an 'A2D Error'?
If your Hach Measuring Instruments displays an 'A2D Error', it indicates the colorimeter is reading zero light throughput. Press the EXIT key to restart the instrument. If the problem persists, inspect the connector pins between the instrument and the colorimeter, straighten them if necessary, and reinstall the colorimeter. If the issue remains, replace the colorimeter.
What to do if my Hach CL17 Measuring Instruments shows a 'Motor Failure'?
If your Hach Measuring Instruments displays a 'Motor Failure' error, it means the pump motor's home position flag was not detected. First, restart the instrument by pressing the EXIT key. If the problem continues, and the motor isn't turning, check that the motor is plugged into the main circuit board, then try replacing the motor or the main circuit board. If the motor runs but the motor coupler is turning, check that the optical switch is properly plugged into the main circuit board and correctly located in the chassis, then try replacing the optical switch or the main circuit board.
What to do if my Hach CL17 Measuring Instruments displays an 'SCR Error'?
If your Hach Measuring Instruments is showing a 'SCR Error', it means that the cycle motor does not turn off at the appropriate time, resulting in a short total cycle time. Press the EXIT key to restart the instrument. If the problem happens again, replace the main circuit board.
Why am I getting a zero reading on my Hach Measuring Instruments?
If you're getting a zero reading on your Hach Measuring Instruments, it could be due to several reasons. Make sure there is a stir bar inside the colorimeter. Ensure the pinch plate thumb screws are fully tightened. Check the sample conditioning and supply lines to ensure the sample is flowing to the instrument. Also, verify that there is only one stir bar inside the colorimeter; remove any excess stir bars.
