Command Usage Tips
• The commands included in the Reg sub-menu can take a long
time to execute in logarithmic,
power regression calculation when there are a large number of
data samples.
n
Base-
The BASE-N Mode lets you perform arithmetic calculations, negative
value calculations, and logical operations with binary, octal, decimal,
and hexadecimal values.
All calculations in this section are performed in the BASE-N
Mode (N4).
