Why does Horiba Measuring Instruments fail to turn ON?
If the device fails to power on, consider these possibilities: * The power supply voltage may be outside the rated range. Check the power supply voltage. * There might be a wiring mistake. Check the power wiring. * The HP-200 has an internal fault. Contact us.
What to do if horiba HP-200 shows E-11 (response speed error)?
The E-11 error indicates a response speed issue. Here's what you can do: * Clean the electrode. If the glass membrane is dried, the response deteriorates. Immerse the electrode in deionized water for 24 hours and then perform calibration again using a standard solution. * If the temperature difference between the solution under measurement and the standard solution is large, wait until the temperature of the temperature compensation element in the electrode becomes stable and then perform calibration using a standard solution.
What to do if horiba HP-200 shows E-71 (glass membrane error)?
The E-71 error indicates a glass membrane issue. Here's what you can do: * Immerse the electrode in the solution under measurement. * Use the specified relay cable and relay box. * If the response membrane of the electrode has cracking, replace the electrode.
What to do if horiba HP-200 shows E-72 (comparison electrode error)?
The E-72 error indicates a comparison electrode issue. Here's what you can do: * Add the internal solution if the internal solution in the comparison electrode has run out. * Clean the electrode if the comparison electrode's liquid junction is clogged. If this does not settle the problem, replace the electrode. * Replace the electrode if the electrode has electrical discontinuity. * The self-check capability is disabled if an electrode without a wetted terminal is used and no short-circuit plate is available. Set self-check is "non."
What to do if Horiba Measuring Instruments shows E-90 (system error)?
The E-90 error indicates a system error. Here's what you can do: * Check the sensor connection and if it is wrong, connect the sensor properly. * Turn OFF the power and then turn it ON again. If the system error does not disappear after the system has been restarted, contact us.
