Calibration Procedure for ND-6018 Firmware Rev E1.00 and
e1.00
1. Power off the module.
2. Connect the default pin to GND.(Because the calibration procedures
must be run under default mode).
3. Power on the module and use utility searching the module.
4. There must a “*” before the address ID.
5. Disable open detect function by sending command “ $00O0”.
6. Only enable Ch0.
7. Select the correct input range. Different input range has to apply different
calibration voltage.
8. Apply the correct offset voltage to channel 0 , detail voltage value, see
table 5-1.
9. Send “ Offset Calibration $(Addr)1 ” to analog input module five
times.(Actually, the address now is “00”, so the command is “$001”).
10. Apply the correct span voltage to channel 0 , detail voltage value, see
table 5-1
11. Send “ Span Calibration $(Addr)0 ” to analog input module five times.
(Actually, the address now is “00”, so the command is “$001”).
* T h e a p p l y s o u r c e m u s t b e a p r e c i s i o n s o u r c e . T h e e r r o r r a n g e i n
±50uV is best.
CJC Calibration Procedure for Firmware E1.00 and e1.00
1. Power off the module.
2. Connect the default pin to GND.(Because the calibration procedures must
be run under default mode).
3. Power on the module and find the module.
4. Ensure that the NuDAM units has been powered up for at least 30 minutes
and is located away from sources of heat, in still air at constant temperature.
5. Place a calibrated temperature meter, with a resolution of 0.1
°
C, in close
proximity to the CJC sensor of the NuDAM module.
6. Send command “ Read CJC Status $(Addr)3 ” to read temperature of CJC,
then compare the temperature returned from the CJC sensor with the
calibrated temperature. (Actually, the address now is “00”, so the command
is “$003”).
7. If the difference is less than
±
0.1
°
C
,
the CJC offset is correctly calibrated, if
it is greater or less, proceed to step 8.
