What to do if Hach Measuring Instruments shows LAMP FAIL?
If the Hach Measuring Instruments displays a LAMP FAIL error, several issues could be the cause. First, the lamp may have burned out and needs replacement. Alternatively, the lamp might be unplugged or dislodged, requiring you to restore the connection or reinstall the lamp. A loose +12 V connection at the controller could also be the problem, so ensure it is properly connected.
What to do if Hach Surface Scatter 7 sc shows VIN FAIL?
If the Hach Measuring Instruments displays a VIN FAIL error, check the cable connection at the sc controller and tighten it if it’s loose. Also, if using an extension cable, make sure only one is present and it is no longer than 7 meters (approximately 30 feet). Fluctuations in voltage can also cause this error, so try turning the instrument power off and back on. In some cases, a bad detector assembly may be the cause, requiring replacement.
What to do if Hach Measuring Instruments shows ADC FAIL?
If the Hach Measuring Instruments displays an ADC FAIL error, first, try turning the instrument power off and then back on, since a fluctuation in voltage may be the cause. If the problem persists, it could be due to a bad detector assembly, which would need to be replaced.
What to do if Hach Surface Scatter 7 sc shows DARK WARNING?
If the Hach Measuring Instruments displays a DARK WARNING, ensure the SS7 sc enclosure door is closed, especially after powering up or performing Zero Electronics. If the door was open, close it and then perform ZERO ELECTRONICS in the CALIBRATION MENU. If the issue continues, the detector assembly may be faulty and require replacement.
Why Hach Surface Scatter 7 sc Measuring Instruments giving low readings?
Low readings on the Hach Measuring Instruments can occur for several reasons. The lens may be coated or dirty, so clean it using isopropyl alcohol and a cotton swab. There might also be an obstruction in the light path that needs to be removed. Also, check for the causes listed under LAMP FAIL.
What to do if Hach Surface Scatter 7 sc Measuring Instruments shows continuous underrange?
A continuous underrange in Hach Measuring Instruments may indicate that the calibration standard was either improperly prepared or unstable during calibration. Verify the accuracy of your calibration standards and then recalibrate the instrument.
