regulations and directives.The instrument must only be operated in a
technicallyawlessandreliablecondition.Theoperatorisresponsi-
ble for the trouble-free operation of the instrument.When measuring
aggressive or corrosive media that can cause a dangerous situation
if the instrument malfunctions, the operator has to implement suitable
measures to make sure the instrument is functioning properly.
During the entire duration of use, the user is obliged to determine the
compliance of the necessary occupational safety measures with the
current valid rules and regulations and also take note of new regula-
tions.

3.2 Principle of operation
The VEGAPULS C 21 SDI-12 can be operated on any data logger
with SDI-12 interface.The sensors are powered via the +12 V cable
of the three-wire connection cable. The device is therefore particu-
larly suitable for battery-supported applications requiring low power
consumption as well as applications with a signal and supply cable
for several sensors.
