What to do if Extech Instruments Measuring Instruments does not turn on?
If your Extech Instruments Measuring Instruments fails to power on with no display, ensure you press the ON-OFF button for at least 100ms. Also, check that the batteries are correctly positioned with proper contact and polarity. If the issue continues, try replacing the batteries or removing and reinserting the existing ones.
How to remove air bubbles from Extech Instruments Measuring Instruments electrode?
To resolve air bubbles adhering to the electrode of your Extech Instruments Measuring Instruments, stir the electrode completely, making sure to dip it into the solution at an angle. If the problem persists, gently tap the bottom of the solution container while stirring the electrode. Alternatively, blow air across the electrode before dipping it into the solution.
Why does Extech Instruments Measuring Instruments display turn off?
If the display of your Extech Instruments Measuring Instruments switches off, this is likely due to the Auto Power OFF feature being activated. If this is not the case, try replacing the batteries.
What to do if Extech Instruments Measuring Instruments shows E03 error?
If your Extech Instruments Measuring Instruments displays an 'E03' error indicating conductivity is over-range, verify with a standard buffer solution. If the problem continues, the meter may require repair.
What does E02 error mean on Extech Instruments Measuring Instruments?
If your Extech Instruments Measuring Instruments shows an 'E02' error indicating the temperature value is below the allowable range or there is temperature circuit damage, check again at room temperature. If the error persists, the meter may require repair.
What does E03 error mean on Extech Instruments Measuring Instruments?
If your Extech Instruments Measuring Instruments shows a 'E03' error indicating the temperature value is above the allowable range or there is temperature circuit damage, check again at room temperature. If the error persists, the meter may require repair.
