Output
None
3-element floating point array.
Nominal power supply values, plus or minus a volt or so.
Volts
The present value of the +15 V power supply.
The present value of the -15 V power supply.
The present value of the +5 V power supply.
The present power supply voltages. Of course you will be lucky to read this
variable if the third element is significantly different from 5V as it would stop the
Neuron chip from working: if it is different it probably indicates that the ADC or its
reference voltage is faulty.
IOVOLTSWAS
output
None
3-element floating point array.
Nominal power supply values, plus or minus a volt or so.
Volts
Stored values of the power supply voltage array IOVOLTS.
Stores the values of the power supply voltages at manufacturing check out time.
Compare the present values to this in order to see what has changed. Only write
into this if the electronic hardware has been changed. There is a special function
in the manufacturing data screen which automatically stores this and other such
variables.
