Why does my Hach Measuring Instruments show E2 error during calibration?
- A
  alexandra12Aug 18, 2025
  The E2 error during calibration on your Hach Measuring Instruments indicates that the difference between the constants is greater than 30%. To resolve this, try the following: * Insert the probe into the appropriate standard and read again. * Clean the probe and the membrane. * Ensure there are no air bubbles in the membrane. * Disconnect and then reconnect the probe. * Connect a different probe to check if the issue is with the probe or the meter. * If necessary, connect a new probe.

Why Hach sensION+ EC5 Measuring Instruments display E3 error during calibration?
- R
  Rachel MorenoAug 21, 2025
  The E3 error during calibration on your Hach Measuring Instruments indicates that the cell constant is less than 0.05 cm-1. To fix it: * Insert the probe into the appropriate standard and read again. * Clean the probe and the membrane. * Ensure there are no air bubbles in the membrane. * Disconnect and then reconnect the probe. * Connect a different probe to verify if the problem is with the probe or the meter.

What to do if my Hach Measuring Instruments displays E4 error?
- Y
  Yesenia RichAug 26, 2025
  The E4 error on your Hach Measuring Instruments means the buffer solution is not recognized. Here's how to troubleshoot: * Clean the probe and the membrane. * Ensure there are no air bubbles in the membrane. * Disconnect and reconnect the probe. * Try a different probe to see if the problem is with the probe or the meter. * Verify that the buffer used matches the buffer specified in the configuration. * Replace the buffer solution. * Check the temperature specification in the configuration.
