• Clean the probe and the membrane.
• Make sure that there are no air
bubbles in the membrane.
• Disconnect the probe and then
connect the probe again.
• Connect a different probe to verify if
problem is with probe or meter.
• Make sure that the buffer used
matches the buffer specified in
configuration.
• Replace the buffer solution.
• Make sure of the temperature
specification in configuration.
E6 The calibration
solutions have
different
temperatures. Make sure that the calibration solutions
have the same temperature.
