5. Analog Output Calibration
5. 1. Calibration
The NuDAM analog output module needs to be calibrated. It
has a factory default calibration . User can use NuDAM
Adminstration utility to do any type of calibration.
5. 2. Analog Output Module Calibration
What do you need to do calibration ?
1. One 5 1/2 digit multimeter
2. A resistor 250 Ω (Accurary is 0.01 %).
3. NuDAM Aministration Utility
Calibration Procedure
1. Select output range to 0 ~20 mA or 4~20 mA.
2. Put the resistor 250 Ω to the NuDAM-6021 (+ IOUT (Pin.1)
and -IOUT (Pin.2))
3. Put 5 1/2 digit multimeter to measure + IOUT (Pin.1) and -
IOUT (Pin.2) .
4. Send the “Analog Data Output #(Addr)(OutData)”
command with output value is 4 mA. For example if the
address is 0x03 then the command is #0304.000
5. Use “Trim calibration $(Addr)3(Counts)” command to
adjust until the output value to 1 V (4 mA).
6. Send “4mA Calibration $(Addr)0” command to the analog
output module to complete the 4 mA calibration.
