What to do if I see fluctuation in measured value with horiba HP-200 Measuring Instruments?

If you observe fluctuations in the measured value, several factors could be responsible: * Air bubbles may be adhering to the electrode. Ensure no air bubbles are generated in the solution. * A fast flow rate might be creating air bubbles. Try controlling the flow rate. * Fluctuations in the solution level can change the wetted area of the electrode. Install the HP-200 to prevent solution level fluctuations. * A sudden change in solution temperature can cause fluctuations. Install the HP-200 in a location with stable temperatures. * A loose screw on the terminal block can cause fluctuations. Firmly tighten the screw. * Moisture on the terminal block can cause fluctuations. Remove any moisture. * A dirty terminal block can cause fluctuations. Clean the terminal block.
