Calculation of output currents

The entire current range (0 – 20 mA or 4 – 20 mA) is available for
one measuring point. However, the current range is divided for two
measuring points. The value from measuring point 1 is displayed in
the lower half (0 – 10 mA or 4 – 12 mA) and the value for measuring
point 2 in the upper half (10 – 20 mA or 12 – 20 mA).

The current is set to 0 or 4 mA (for 1 measuring point)
The current is set to 20 mA.
Measured value = The value shown on the display in the selected
hardness unit
Maximum value = The end value of the applied indicator
(e.g. indicator 2005 = 0.5 °dH)

Serial interface RS232

®
Testomat 2000 can also be connected to a log printer via the serial
interface RS232 to enable the printout of measuring results and error
messages. Analyses can then be continuously logged. This option is
only possible in connection with the plug-in card RS910 (Art. no.
270310).
