DS-100C Operating Manual IVPC Software Reference page 27
Read I & V “B”
This command reads the DS-100C current and voltage analog-to-digital
converters (ADCs), and repeatedly outputs their 16 bit integer values until
another command is received. Note: Any command sent to it to stop this
command is ignored. Typically this command is used to calibrate the DS-Tracer.
Note: These values may or may not have had offset correction applied
depending on the whether the “Z” parameter is passed (see below).
Format
“B,n1,n2,[Z]” n1 = Voltage gain code 0,1,2, or 3.
n2 = Current gain code 0,1,2, or 3.
Z = Use current offset values (see auto
zero)
Gain Codes
0 = 1X used for 600 V, not used for current
1 = 10X used for 60 V, 100 A
2 = 100X used for 6 V, 10 A
3 = 1000X not used for any measurements
Example
command “B,0,1” or “B,0,1,Z”
response “*”
response “3045” Voltage A/D Output.
response “2839” Current A/D Output.
delay
response “3046”
response “2838”
Continues until any other command is received..
Auto Zero I & V “Z”
This sets the current circuit offset to the current reads form the PV voltage and
current channels. Therefore this command should only be used when the current
