What to do if my Horiba Measuring Instruments shows DATA FULL?
If the Horiba Measuring Instruments displays 'DATA FULL', it means the maximum number of saved data has been exceeded. To resolve this, print or transfer all data, and then clear the data log.
Why does the indicated value fluctuate on my Horiba Measuring Instruments when it is problem with the electrode?
If the indicated value on your Horiba Measuring Instruments fluctuates, and it's due to the electrode, it could be for several reasons: * The electrode is dirty: Clean the electrode. * The electrode is cracked: Replace the electrode. * The wrong internal solution is being used: Use the correct internal solution. * There are air bubbles on the electrode: Shake the electrode to remove the air bubbles. * The level of internal solution in reference electrode is low: Replenish the internal solution of the reference electrode until it is higher than the level of the sample.
Why does the indicated value fluctuate on my Horiba Measuring Instruments when it is problem with the instrument?
If the indicated value on your Horiba Measuring Instruments fluctuates, and it's due to the instrument, it could be due to: * Electrical interference: Measure in a location free from induction and ground all AC-powered equipment. * Incorrect electrode connection: Ensure the electrode is properly connected.
Why is the repeatability of the measured value poor on my Horiba Measuring Instruments?
If the repeatability of the measured value is poor on your Horiba Measuring Instruments, it could be due to: * The effect of the sample solution: Repeatability becomes poor when the pH of the sample changes over time. * The electrode is dirty: Clean the electrode. * The electrode is broken: Replace the electrode. * The internal solution of the electrode runs out or contaminated: Replace the internal solution with a new one. * The level of internal solution in reference electrode is low: Replenish the internal solution of the reference electrode until it is higher than the level of the sample.
What does NOT STBLE mean on my Horiba Measuring Instruments and how to fix it?
If your Horiba Measuring Instruments shows 'NOT STBLE', it means the ENT key was pressed before the smiley icon and calibration value stabilized. Wait for the smiley icon and calibration value to stabilize before pressing the ENT key.
How to fix OFFS ERR on Horiba Measuring Instruments?
If your Horiba Measuring Instruments displays 'OFFS ERR', it indicates that the electrode is either dirty or the reference junction is clogged. Clean the electrode to resolve this issue.
What causes SLPE ERR on Horiba Measuring Instruments?
If your Horiba Measuring Instruments displays 'SLPE ERR', it indicates that the electrode sensitivity is low. Clean and recalibrate with a fresh standard solution. If the problem continues, replace the electrode.
What does BUFF ERR mean on Horiba Measuring Instruments?
If your Horiba Measuring Instruments displays 'BUFF ERR', it means the instrument cannot identify the pH buffer. Check the calibration solution and use a fresh one if necessary.
Why does the indicated value not change on my Horiba Measuring Instruments?
If the indicated value on your Horiba Measuring Instruments does not change, it could be due to several reasons: * The electrode is cracked: Replace the electrode. * The electrode is not connected correctly: Connect the electrode correctly. * The instrument is in HOLD state: Cancel the HOLD state. * Instrument defect: Consult your dealer.
What does CAL DUE mean on my Horiba Measuring Instruments?
If your Horiba Measuring Instruments displays 'CAL DUE' and the electrode icon blinks in MEAS mode, it means calibration was not performed at the designated interval. Perform calibration.
