(Overflow detection Push locking (Required tool: Adjustment pin 2 mm, Art. no. 30990) ring upwards Testomat 2000 ® / ECO instruments have been factory set. Therefore, instrument adjustment during start-up is not required. All instruments from instrument number 222.899 and higher are equipped with a self-adjusting electronic circuit.
Carrying out maintenance Subsequently turn the potentiometer anti-clockwise by an approx. 1/8 turn. Check correct functioning of the overflow detection circuit via the key M = input valve: The "Analysis" LED must illuminate while wa- ter is overflowing. Press key M again for quitting. The LED must extinguish once the overflow has finished.

Carrying out maintenance Repairing or replacing the dosing pump Maintenance rate NOTE ® The dosing pump DOSIClip is a high-precision piston dosing pump, which makes up to 400 000 pump strokes per year depending on the settings (a measurement all 10 minutes x 4 pump strokes every day). To ensure proper operation for many years, we recommend sending in the pump for servicing every 2-3 years.
Special function “Adjust mode” Checking dosing When measuring the hardness, it is checked whether the yellow val- ue is at least 50 below the limit value after each (except the first) dosing stroke. Each stroke usually results in the value being reduced by 80 to 100 digits.
Press the “M” (3) key to open the input valve IN. : the “IN” LED (6) illuminates. ® Only Testomat 2000 The “ANALYSIS” (7) LED must illuminate when the water flows through the overflow borehole of the measuring chamber (If this is not the case, adjust the overflow detection as described above).
Water consumption Water consumption Water consumption of the instruments is composed of the analysis- relevant volume (18.1 ml per analysis), of the measuring water ad- justment (150 – 200 ml per analysis), the water consumption for the internal flushing time 0.5 l (500 ml /minute). and the water consump- tion for flushing after analysis (approx.
