Important safety information Installation Always completely disconnect the relevant plant part before in- stalling the instrument or connecting/disconnecting it to/from the power supply. Secure the plant against reconnection. WARNING Only connect the instrument to the mains voltage specified on the rating plate.
Scope of delivery Scope of delivery ® 1x Testomat 2000 1x plastic bag with two screw caps with a hole and inserts for the screw caps of the reagent bottles 1x operating instructions Performance specifications ® The process photometer Testomat 2000 Fe is used for automatically monitoring the dissolved iron content (II)+(III) from 0 to 1.0 mg/l using a colourimetric analysis principle.
Application instructions Application instructions Wait at least 5 seconds before switching the instrument on and then off again at the main switch. ® Trouble-free operation of Testomat 2000 Fe is only possible ® when using Heyl Testomat 2000 reagents FE2005A and FE2005B ! Faults or problems resulting from the use of other rea- gents will not be accepted as a warranty or fair dealing claim.
Installation Installation Risks resulting from incorrect installation! ® WARNING Install Testomat 2000 Fe at a location where it is protected against dripping or splash water, dust and aggressive substances – e. g. in a switch cabinet or on a suitable wall. ...
Installation Connecting the water inlet and outlet Information for trouble-free operation The water pressure must be between 0.3 bar and 8 bar. NOTE Avoid strong pressure fluctuations. The measuring water temperature must be between 10°C and 40°C. Higher water temperatures can damage the parts which come into contact with the water (e.g.

Entering further basic program data Entering further basic program data For selecting and entering data for these functions, please proceed as described under "Entering basic program data". Internal flushing To ensure that the analysed sample represents the current value, the sampling line must be sufficiently flushed.
Entering further basic program data Interval pause If the analysis is started via a timer, the interval between two anal- yses (plus flushing time) is determined by the interval pause. The shortest interval can be 0 minutes. In this case, analyses are carried out continuously.
Entering further basic program data Hysteresis The respective limit value output only switches after the first, second Suppression of or third bad analysis (suppression of the first or the second measured bad analyses value). This increases the reliability of the analysis evaluation, e.g. after the measuring point has been switched over or if the sampling line has not been flushed sufficiently.
