Introduction
Dear customer,
By purchasing the Current Calibrator CC - 421 you have acquired a
high-precision calibration tool for you measurement device(s) desi-
gned according to the state of the art. The current source can sup-
ply up to 24 mA max. at 400 ohm. DC current measurement up to 24
mADC and loop current measurements also up to 24 mADC can be
performed with the 2-conductor loop being supplied with 12 VDC
from the device. The current calibrator can also be applied as DC
voltage source from –199.9 to +199.9 mVDC.
The current calibrator was designed according to EN 610610 – 1
(= DIN VDE 0411 / Part 1). The measurement device is EMC-tested
and thus corresponds to the requirements of the relevant national
and European guidelines. Conformity has been proved; the rele-
vant documents are in the possession of the manufacturer.
To preserve this condition and to enable safe operation, you as the
user must observe these operating instructions!
