6 Calibration
The two digital-to-analog (DAC) and the analog-to-digital (ADC) converter of
the
ADwin
system have been calibrated in factory. In accordance with the reg-
ulations for keeping the measurement accuracy in your field of application, the
systems must be calibrated in regular time intervals.
Calibration is made via software. You will find the program
<L16Calib.exe>
under the path
<C:\ADwin\Tools\ADwin-L16>
(at standard installations).
You need the following tools for the calibration:
– a digital multimeter (DMM) with a resolution of 30 µV.
– a reference voltage source with a resolution of 30 µV. Optionally you
connect DAC 1 to ADC 01(+), DAC 2 to ADC 03(+) and AGND DAC
with ADC 01(-) and ADC 03(-), for instance in form of a test connector.
You need these connections also for the calibration diagram.
– connection cables from the inputs/outputs to the reference voltage
source and to the measurement device.
Step 1
Connect your
ADwin-light-16
system with the PC and configure it with the pro-
gram
<ADconfig.exe>
.
Step 2
Start the
calibration program
<L16Calib.exe>
. The window "
ADwin-
light-16 Calibration Tool
" appears.
Select the device number of the system to be calibrated and confirm by press-
ing "
OK
".
You will get a warning, if you haven’t selected an
ADwin-light-16
system or if
you have selected one with an older firm ware version. You can ignore the
warning with "
YES
" or return to the previous windows with "
NO
".
An
overview window
appears. In the header the selected device number is
displayed.
