Model 6485 Picoammeter Instruction Manual DISPlay, FORMat, and SYSTem 13-7
Bit 7 (Overvoltage) — Set to 1 if measurement performed with an overvoltage condition
on the input.
Bit 9 (Zero Check) — Set to 1 when zero check is enabled.
Bit 10 (Zero Correct) — Set to 1 when zero correct is enabled.
Example — The ASCII data string contains all three data elements. The status value of
138 has a binary equivalent of 01001010, which indicates that bits B1, B3, and B7 are set.
Therefore, the reading is 1.04056uA with null (REL) and the AVG filter enabled. The
reading was taken 223.6299 seconds after the instrument was turned on.
C) FORMat:BORDer <name>
Parameters NORMal = Normal byte order for IEEE-754 binary format
SWAPped = Reverse byte order for IEEE-754 binary format
For normal byte order, the data format for each element is sent as follows:
Byte 1 Byte 2 Byte 3 Byte 4
For reverse byte order, data is sent as follows:
Byte 4 Byte 3 Byte 2 Byte 1
The “#0” header is not affected by this command. The header is always sent at the begin-
ning of the data string for each measurement conversion.
The ASCII data format can only be sent in the normal byte order. The SWAPped selection
is ignored when the ASCII format is selected.
NOTE The SWAPped byte order must be used when transmitting binary data to any
IBM PC.
