Factory Software Calibration
t is recommended that a 16-bit A/D card is used to calibrate the PISO-DA/PIO-DA series cards.
The I-7000 series is a set of precise remote control modules and the I-7017 is an 8-channel
16-bit precision A/D module (24-bit sigma-delta A/D converter). Two I-7017 modules are
used for voltage output calibration and another two for current output calibration.
The steps required to calibrate the voltage for channel_n are as follows:
Step 1:
DaValue=0
Step 2:
Send the DaValue to channel_n on the PIO/PISO card
Step 3:
Measure the voltage of channel_n on the I-7017
If this value is >= -10 V, then go to Step 5
Step 4:
Increase the DaValue, then return to Step 2
Step 5:
MinV[n]=DaValue-1
Step 6:
DaValue=0x3fff
Step 7:
Send the DaValue to channel_n on the PIO/PISO card
Step 8:
Measure the voltage of channel_n on the I-7017
If this value is >= +10 V, then go to Step 10
Step 9:
Increase the DaValue, then return to Step 7
Step 10:
MaxV[n]=DaValue
Note: MinV[n] and MaxV[n] are described in
