DISPlay, FORMat, and SYSTem
Bit 2 (Math) — Set to 1 when measurement performed with CALC1 enabled.
Bit 3 (Null) — Set to 1 if null for CALC2 is enabled.
Bit 4 (Limits) — Set to 1 if a limit test (CALC2) is enabled.
Bits 5 and 6 (Limit Results) — Provides limit test results:
Bit 6
0
0
1
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 on
tus value of 138 has a binary equivalent of 01001010, which indicates that bits B1, B3, and
B7 are set. Therefore, the reading is 1.04056µA with null (REL) and the AVG filter
enabled. The reading was taken 223.6299 seconds after the instrument was turned on. The
voltage source was on and set to +123.45V.

Parameters
For normal byte order, the data format for each element is sent as follows:
Byte 1
For reverse byte order, data is sent as follows:
Byte 4
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.
