  If the Testomat Analytical Instruments show error E2, indicating a measuring fault, begin by checking if the indicator bottle is empty and ensure the indicator matches the quantity in the bottle. Only use approved indicators for the Testomat 808, as others can cause errors. Also, verify the stirring bar is present and turns, the pump supplies indicator, and the dosing needle isn't blocked or has a damaged O-ring. Make sure suction and pressure hoses aren't drawing secondary air, and check the suction lance for air bubbles escaping from the dosing needle.

  If your Testomat Analytical Instruments display error E4, it indicates insufficient LED power or light. Here's what you should check: * First, see if the water is turbid, as turbidity affects measurements. * Inspect the measuring chamber/sight glass for soiling. * Consider the possibility of a damaged sensor or LED. * Ensure the water level isn't too low. * Confirm the measuring chamber and LED fitting are correctly installed, as transport can loosen them. Also, you may need to perform a visual adjustment according to the Testomat 808 maintenance instructions.
