6.3 Analog output module calibration
The output current of analog output modules can be calibrated by using
a low calibration value and a high calibration value. The analog output
modules can be configured for one of two ranges: 0-20 mA and 4-20 mA.
Since the low limit of the 0-20 mA range (0 mA) is internally an absolute
reference (no power or immeasurably small power), just two levels are
needed for calibration: 4 mA and 20 mA.
1. Apply power to the ADAM-5000 system including the analog output
module for about 30 minutes.
2. Assure that the module is correctly installed and that its configuration
is according to your specifications and that it matches the output range
you want to calibrate. You can do this by using the ADAM utility
software.
3. Connect either a 5-digit mA meter or voltmeter with a shunt resistor
(250 ohms, .01 % and 10 ppm) to the screw terminals of the module.
