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 20 mA.
Measured value = the value shown on the display in the selected unit
Maximum value = the end value of the applied reagent (10 mg/l)

Serial interface RS232

®
Testomat 2000 PO4 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 RS-232 interface card
for log printer, RS910 (Art. no. 270310).
