6.1 General information
The digital-to-analog (DAC) and analog-to-digital (ADC) converters of the
ADwin
systems are calibrated in factory. According to the regulations for mea-
surement accuracy, we recommend calibrating the systems in regular time
intervals.
Qualified personnel
Programming, start-up and operation, as well as the modification of program
parameters must be performed only by appropriately qualified personnel.
Qualified personnel are persons who, due to their education, experience
and training as well as their knowledge of applicable technical stan-
dards, guidelines, accident prevention regulations and operating condi-
tions, have been authorized by a quality assurance representative at the
site to perform the necessary acivities, while recognizing and avoiding
any possible dangers.
(Definition of qualified personnel as per VDE 105 and ICE 364).

Tools
The following tools are necessary to calibrate the system:
– a reference voltage source with an accuracy of:
• 10µV for calibration of 18-bit converters
• 30µV for calibration of 16-bit converters
• 100µV for calibration of 14-bit converters
– a digital multi meter with an accuracy of:
• 10µV for calibration of 18-bit converters
• 30µV for calibration of 16-bit converters
• 100µV for calibration of 14-bit converters
– connecting cables from the input/outputs to the reference voltage and to
the measurement device
Caution: Risk of electric shock.
ADwin-Pro
systems have a power supply device, which gives
access to high-voltage lines and connectors if the system is open.
The ventilation slots are wide enough to pass through an align-
ment tool of 2.5 mm (=0.1inch).
Calibrate the system only when it is closed!
Do not pass any conductive objects through the ventilation slots!
