What to do if JENCO 6308PT Controller shows 'OVER' and pH is greater than 16.00?
If the JENCO Controller displays 'OVER' and the pH reading exceeds 16.00, it indicates an over range condition. You should either recalibrate the device.
What to do if JENCO 6308PT Controller displays 'OVER' with high mV offset?
If the JENCO Controller displays 'OVER' with a high mV offset (Offset @ 7.00pH: mV>100mV or Offset@6.86pH: mV>108.3mV) or if the new slope exceeds the ideal slope by 30%, use a new buffer solution. If the problem persists, replace the electrode.
What to do if JENCO 6308PT displays 'UNDR' with low mV offset?
If the JENCO Controller displays 'UNDR' with a low mV offset (Offset @ 7.00pH: mV
What to do if JENCO Controller displays 'OVER' because of low temperature?
If the JENCO Controller displays 'OVER' and the temperature is less than -10.0°C, bring the buffer or solution to a higher temperature.
What to do if my JENCO Controller shows 'EEPROM: BAD'?
If your JENCO Controller displays 'EEPROM: BAD', turn the instrument off and then back on again. If the issue persists, return it for service under the warranty.
What to do if my JENCO Controller shows 'ROM : BAD'?
If your JENCO Controller displays 'ROM : BAD', turn the instrument off and then back on again. If the issue persists, return it for service under the warranty.
What to do if my JENCO 6308PT shows 'RAM : BAD'?
If your JENCO Controller displays 'RAM : BAD', turn the instrument off and then back on again. If the issue persists, return it for service under the warranty.
