Power-on operation_a,operation_b = OFF,OFF.
Default operation_a,operation_b = OFF,OFF.
Power-on register values = all registers are set to 0 with the following exceptions:

Remarks
The FILTER, RMS, STAT, or PFAIL math operations are performed on all
subsequent readings. However, whenever the multimeter's configuration is
changed, the previous math results are erased and the operation starts over on
the new readings. All other math operations stay enabled until you set MATH
OFF, execute the MATH command specifying other math operation(s), or
enable post-process math operation(s) (except MMATH PFAIL or MMATH
STAT as described under the MMATH command).
•
When two real-time math operations are enabled, operation_a is performed on
the reading first. Next, operation_b is performed on the result of the first
operation.
•
When a real-time math operation is enabled, the display's half digit becomes a
full digit. For example, if you are making 4.5 digit AC voltage measurements
and then enable the SCALE math operation, the display is capable of showing
5 full digits.
•
Math registers may be written to with the SMATH command. Math registers
may be read with the RMATH command.
•
Query Command. The MATH? query command returns two responses,
separated by a comma, which indicate the enabled real-time math function(s).
Refer to "Query Commands" near the front of this chapter for more information.
