How to fix ECAL error on Hach Test Equipment?
If 'ECAL' appears on your Hach Test Equipment, it indicates a calibration failure, specifically that the pH calibration slope is greater than ±15%. Gently clean the sensor, then calibrate again. If the calibration failure continues, replace the tester or sensor as needed.
What to do if the battery icon flashes on Hach Pocket Pro Test Equipment?
If the battery icon is flashing on your Hach Test Equipment, it means the batteries have less than 10% power remaining. Replace all four batteries to resolve this issue.
What to do if Hach Test Equipment shows "- - - -" on the top line?
If you see "- - - -" on the top line of your Hach Test Equipment, it means the parameter value is not within the measurement range of the tester. Make sure that the sample's value is within the tester's measurement range. Also, gently clean the sensor and calibrate if necessary.
How to fix 'SENSOR?' error on Hach Test Equipment?
If your Hach Test Equipment displays 'SENSOR?', it means the calibration slope is ±10–15%. To fix this, gently clean the sensor.
Why does Hach Test Equipment show "- - - -" on the bottom line?
If the Hach Test Equipment displays "- - - -" on the bottom line, it indicates that the temperature value is not within the operating temperature range of the tester, or a temperature sensor failure has occurred. Ensure the sample temperature is within the tester's operating temperature range. Note that the tester can still be used without automatic temperature compensation if a temperature sensor failure occurred.
What to do if the battery icon flashes on my Hach Measuring Instruments?
If the battery icon flashes, it means the batteries have less than 10% power remaining. Replace all four batteries.
What to do if my Hach Measuring Instruments displays ' - - - - '?
The display ' - - - - ' indicates that the temperature value is not within the measurement range of the tester. Ensure the sample temperature is within the measurement range. Gently clean the sensor and calibrate if needed.
How to fix "- - - -" on Hach Pocket Pro?
If your Hach Test Equipment displays "- - - -" on the top line, it indicates that the parameter value is outside the tester's measurement range. Ensure your sample's value is within the specified range. You may also need to gently clean the sensor and calibrate the device.
