Changing MATH function
• If you started with only a basic measurement function selected, you can enable a
MATH function, but only the voltage, current, or resistance component of the calcula-
tion will be stored in the buffer. The results of the MATH function will not be stored.
• If you started with a MATH function enabled, you can select a different MATH func-
tion. The results of the new MATH function are stored in the buffer.
• If you started with REL and/or LIMITS enabled, the buffer will stop storing readings if
you select a MATH function. Storage will continue if you return to the original configu-
ration.
See Section 7 for more information on MATH.
Changing REL or LIMITS
• If you started with only a basic measurement function selected, you can enable REL
and/or LIMITS, but only the voltage, current, or resistance component of the operation
will be stored in the buffer. The results of REL and/or LIMITS are not stored.
• If you started with a MATH function enabled, only the result of the MATH calculation
will be stored in the buffer if REL and/or LIMITS is enabled.
• If you started with REL and/or LIMITS enabled, you can change REL and or LIMITS.
The results of new REL and/or LIMITS are stored in the buffer.
See Section 7 for REL information and Section 11 for details on LIMITS.
