Check Probe / Check Buffer
“CHECK PROBE CHECK BUFFER” is displayed when the electrode's slope exceeds the
highest accepted slope limit. Inspect the electrode and make sure the buffer solution is
fresh. Clean the probe to improve response time.

Wrong Buffer Temperature
“WRONG TEMP” is displayed if the temperature of the buffer 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.
