Why is 'AR' blinking and the reading not changing on my EUTECH INSTRUMENTS 2700 Measuring Instruments?
If your EUTECH INSTRUMENTS Measuring Instruments reading doesn't change and 'AR' is blinking, it means Auto-Read is active. This function automatically locks the measurement when it's stable. To continue, press MEAS. If you prefer the reading to change continuously, disable Auto-Read in the settings.
How to fix faded main digits on EUTECH INSTRUMENTS Measuring Instruments?
If all main digits are faded too often on your EUTECH INSTRUMENTS Measuring Instruments, it's likely due to the 'Stability' feature being enabled. When enabled, the digits will fade when the reading is unstable and become solid when stable. You can either disable this feature to keep the digits solid at all times or keep it enabled and change the 'Stability Criteria' to 'Slow'.
What to do if my EUTECH INSTRUMENTS Measuring Instruments says 'Memory Full'?
If your EUTECH INSTRUMENTS Measuring Instruments displays 'Memory Full', it's likely due to a timed datalog running until the memory is exhausted. To clear the stored data, navigate to System Setup and select CLEAR LOG.
What to do if pH reading is stuck at 7.00 on my EUTECH INSTRUMENTS Measuring Instruments?
If your EUTECH INSTRUMENTS Measuring Instruments displays a pH reading of 7.00 that won’t change, the electrode tip may be cracked or broken. Replace the electrode to resolve this issue.
How to fix pH or Ion Slope error on EUTECH INSTRUMENTS Measuring Instruments?
If your EUTECH INSTRUMENTS Measuring Instruments gives a pH or Ion Slope error/Calibration error, it means the calibration values are too far apart or too far from ideal values. Check the electrode, use fresh buffers, and verify the meter settings. The electrode may need filling solution, conditioning, or replacement. Consult the electrode manual for further guidance.
Why are pH calibration points too close on my EUTECH INSTRUMENTS 2700 Measuring Instruments?
When calibrating pH on your EUTECH INSTRUMENTS Measuring Instruments, custom pH buffer calibration values must be at least 1.0 pH unit apart.
Why is DO reading slow to stabilize on EUTECH INSTRUMENTS 2700?
If your EUTECH INSTRUMENTS Measuring Instruments DO reading is very slow to stabilize, ensure the stirrer motor is on during solution measurement and the temperature is stable. If the electrode is old, the gold cathode may be tarnished—buff it with a disk or pencil eraser. You might also need to replace the membrane and electrolyte and recondition the electrode.
Why does the 2nd conductivity calibration point replace the 1st on my EUTECH INSTRUMENTS 2700?
If the conductivity 2nd calibration point replaces the 1st on your EUTECH INSTRUMENTS Measuring Instruments, remember that only one point per range can be calibrated. Re-consider your SINGLE or MULTI Cal Points setting.
How to fix TDS standard mismatch on EUTECH INSTRUMENTS 2700 Measuring Instruments?
To correct the TDS value on your EUTECH INSTRUMENTS Measuring Instruments when the standard does not match, adjust the TDS factor as needed. Refer to “Calculating TDS Conversion Factor”.
Why does my EUTECH INSTRUMENTS Measuring Instruments ion display read '- - -'?
If your EUTECH INSTRUMENTS Measuring Instruments ion display reads '- - -', a 2-point Ion calibration is required because no calibration is stored in memory.
