Check List Testomat 2000
Dear customers and service technicians,
This check list cannot replace your expertise or extensive experience in fault resolution. It is intended to support fast and systematic error diagnosis
and error documentation. This list does not claim to be complete. We are therefore always grateful for any advice and information you may be able
to provide. General user instructions can be found on the rear of this check list.
The Instrument Manufacturer
Block 1 / Plant and instrument data
Plant type
Block 2 / Error message and error history
What does your instrument's error history display?
("i" and "Enter" key => operating instructions)
Does an error message appear on the display?
For example, "Mf. analysis", "Low water level", etc.
(See operating instructions: "Error messages /
Troubleshooting")
Block 3 / Visual inspection and functional test
Is the instrument connected to the mains voltage specified on the rating plate?
Does a message appear on the display?
Does the instrument display a plausible measured value?
(possible manual measurement ___________ value)
Are the measuring chamber and sight-glass windows clean?
Are the measuring chamber and the water-carrying hoses free of leaks?
Is the indicator's expiry date still valid?
(See expiry date printed on the indicator bottle)
Is the water pressure within the specified range (400 ml/min)?
(See the type plate on the instrument)
Does the drain hose prevent the risk of backwater?
(No "syphoning effect"!!)
Is the drain hose free of blockages?
(Microorganisms caused by contamination, etc.)
Does the set flushing time/quantity of flush water ensure that only freshwater
is measured?
Are the hoses at the dosing pump free from air bubbles?
(Operate the pump manually / Carry out a manual analysis)
CARRYING OUT A (MANUAL) ANALYSIS
Does the water column rise evenly up to the overflow borehole when filling the
measuring chamber (5 mm below the upper edge of the measuring chamber)?
(If not: check the water pressure, water throughput/flow controller)
Does the indicator pump dose correctly when starting an analysis?
(LED at the pump illuminates!)
Have the indicator and water been mixed properly in the measuring
chamber after the dosing process?
Check the magnetic stirring bar! =>see maintenance manual "Adjust mode"
PROGRAMMING DATA / OPERATING CONDITIONS
Have the limit values been set correctly? (Within the measuring
range/according to the performance limit of the plant?)
Is the Testomat instrument always supplied with mains voltage – except
during maintenance work/emergency situations?
(Temporary shutdown only via the "Standby" key or the "Stop" input!)
Please refer to "Error messages / Troubleshooting" in the operating instructions for further information on error messages and possible causes
of faults.
Further functional tests (e.g. overflow detection and amplification setting => "Special function Adjust mode") and service instructions can be found
in the maintenance manual.
After completing these checks, experience shows that it can be assumed that the checked functions (Block 3) are in effective working order if you
have answered all the questions with "Yes". We recommend you to carry out these checks during each inspection or if faults occur.
