but the parser assumes that the two implied keywords are there. For the same reason, you can query the immediate

resistance value with:

RES?

Note When sending a query, do not enter a space between the keyword and the question mark.

The newline character < nl > or EOI terminator sends the parser back to the root level. Many controllers automatically send

this character at the end of each program output string. To program the resistance range and the TLEVel value, you could

send:

RES:RANG 1000 < nl >

RES :TLEV 5000 < nl >

Note There is an alternate way to do this, which is shown under ''Traversing the Command Tree.”’

Using the NRf+ Format

Referring to Figure 3-2, note that all parameters are of the <NRf+ > type. This allows you to easily set a numeric parameter

to its maximum or minimum value. If you wanted to increase the immediate resistance of the presently selected range to its

maximum value, you could send:
