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 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.
Why does Hach Measuring Instruments show "Access Denied" message?
If you receive an "Access Denied" message on the Hach Measuring Instruments, it indicates that the user account you're using does not have the necessary permissions. To resolve this, give the required accessibility permissions to the user, or log in as a different user who has sufficient permissions.
What to do if Hach Measuring Instruments shows "Invalid Password" message?
If you're seeing an "Invalid Password" message on your Hach Measuring Instruments, it means the password entered is incorrect. Try entering the correct password, or select a different user name.
How to fix network connection on Hach Measuring Instruments?
If the network connection isn't showing on your Hach Measuring Instruments, the ethernet cable may not be connected. Ensure the ethernet cable is properly connected to the instrument.
Why the auto sampler does not operate on Hach Measuring Instruments?
If the auto sampler on your Hach Measuring Instruments isn't operating, check that the USB cable from the auto sampler is correctly connected to the instrument and that the power is on. Large electrical transients on the power line may disrupt the USB communication. To resolve this, install a commercially available USB opto-isolator between the analyzer and the auto sampler. Then, power cycle both instruments by setting the power to off and then on again.
