How to fix slow measurements on Hach QbD1200 Measuring Instruments?
To fix the issue where measurements take too long or the results are consistently too low on your Hach Measuring Instruments, replace the UV reactor, as it may be nearing the end of its life. Also, ensure that you have a sufficient quantity of carrier gas and that all fittings around the reactor are tightened properly.
Why the USB import/export function does not operate with Hach QbD1200?
If the USB import or export function on your Hach Measuring Instruments isn't working, start by checking if the USB flash drive is properly connected. If it is connected, the drive may be corrupted or not recognized. Try fixing or formatting the USB flash drive, and then reconnect it to the instrument.
What to do if USB drive is not working with Hach Measuring Instruments?
If the USB import or export function isn't working with your USB flash drive on the Hach Measuring Instruments, first, ensure the USB flash drive is properly connected to the instrument. If it is connected, the drive may not be recognized or could be corrupt. Try fixing or formatting the USB flash drive, and then reconnect it to the instrument.
Why user interface error messages appear during menu changes on Hach Measuring Instruments?
If user interface error messages are appearing during menu changes on your Hach Measuring Instruments, it indicates an error in the user interface firmware. Turn the instrument power off, and then on again.
What to do if UV reactor does not work on Hach Measuring Instruments?
If the UV reactor does not work on your Hach Measuring Instruments, it may be expired or damaged. Replace the UV reactor.
What to do if the system test fails on Hach Measuring Instruments?
If the system test fails on the Hach Measuring Instruments, it could be due to an error during the system test or because the UV reactor is almost expired. Ensure that the carrier gas supply is correctly connected. Also, replace the UV reactor and make sure there is a sufficient quantity of carrier gas.
Why significant carryover occurs from sample to sample with Hach Measuring Instruments?
If significant carryover occurs from sample to sample on your Hach Measuring Instruments, it means that the reactor is not fully flushed after each measurement. Examine the carrier gas supply.
What to do if Hach Measuring Instruments shows that sample is not found?
If the sample is not found by the Hach Measuring Instruments, it could be due to several reasons. First, ensure that there is enough solution in the reagent bottle by filling it with solution. Next, check that the sample tube is properly connected to the auto sampler and is correctly placed in the sample flask. Finally, ensure that there is a sample to use for the procedure.
Why measurements on Hach Measuring Instruments show the result as "0"?
If measurements frequently show the result as "0" on your Hach Measuring Instruments, it is because the background TOC reading is larger than the sample TOC reading. Fill the reagent bottle with water, then perform a new background qualification procedure.
What to do if Hach Measuring Instruments does not accept new password?
If the new password is not accepted on your Hach Measuring Instruments, it means the password and the confirmation password do not match. Ensure that you enter the same password in both fields.
