“BAD ELEC” is displayed when after cleaning, the electrode’s performance has not
improved. Replace the probe.
y
“WRONG STANDARD TEMPERATURE” is displayed when buffer temperature is out
of range. The calibration buffers are affected by temperature changes. During
calibration, the instrument will automatically calibrate to the pH value corresponding
to the measured temperature but compensate it to the value of 25 °C.
y
When “CONTAMINATED BUFFER” is displayed, replace the buffer with a new one and
continue the calibration.
y
“VALUE USED BY CUST 1” or “VALUE USED BY CUST 2” message is displayed when
attempting to set a custom buffer of the same value as the one previously set. Make
sure that set custom buffers have different values.
