the readings are unstable, it may be necessary to
replace the electrolyte solution in the probe head.

2. Pour out the old electrolyte solution from the
probe head.
3. Fill the probe head with fresh electrolyte
solution.
4. Replace the probe head and tighten securely,
do not overtighten.

A damaged diaphragm can cause the calibration
check to return incorrect results (see the “Calibration
Check” section) or cause the readings to be
unstable or inaccurate. The diaphragm may be
damaged if it comes into contact with a solid
object, or is subjected to impacts. The diaphragm
is integrated into the probe head.
