Why won't my Hach Measuring Instruments power on?
If your Hach Measuring Instruments meter won't power on, there may be a few reasons. First, check the battery orientation to ensure it matches the polarity markings. If that doesn't work, try cleaning the battery terminals and installing new batteries. You can also connect an AC power adapter to test. If the issue persists, it could be due to a damaged meter.
What to do if Hach Measuring Instruments displays '0 days remaining'?
If your Hach Measuring Instruments meter displays a '0 days remaining' message (specifically for LDO and LBOD), it means the LDO or LBOD sensor cap has been used for 365 days and needs to be replaced, along with the iButton®. Alternatively, it could indicate that the meter's date and time are set incorrectly. To resolve this, disconnect the probe, remove the meter batteries, reinstall them following the polarity markings, set the correct date and time, and then reconnect the probe.
What to do if Hach HQ411d says 'Probe Not Supported'?
If your Hach Measuring Instruments displays a 'Probe Not Supported' message, first, ensure the probe is properly connected by tightening the locking nut on the probe connector. If the issue continues, disconnect the probe and then reconnect it. To determine if the problem lies with the probe or the meter, try connecting a different IntelliCAL probe to the meter.
