HP E1312A/E1412A Resolution Using Special Functions
and Ranges

Resolution Example

Appendix C
Resolution remains a function of the NPLC parameter set at the time a
special function or range is used. The NPLC setting is fixed throughout use
of the special functions and ranges unless you change the setting with the
[SENSe:]< function
CONFigure command using a resolution that changes the NPLC setting. The
resolution will track the NPLC setting as shown in Tables 3-1, 3-2, and 3-3
beginning on page 70.
The following table shows range and NPLC settings for power-on and after
a module reset. Changing a range within one function does not place other
functions at that range setting. Each function operates independently.

Note
Refer to Tables 3-1, 3-2 and 3-3 in Chapter 3, to determine what resolution
will result following a special function or special range change. The NPLC
setting remains fixed for each function during execution of the special
function and range commands (e.g., may differ from function to function).
Assume the power-on state where the multimeter function is DC Voltage,
10V range, with an NPLC setting of 10 PLCs providing 10µV resolution
(see Table 3-1 on page 70). Use the special range command R5 to change
the DC Voltage range to 300V. The NPLC setting remains at 10 PLCs
providing a resolution of 1mV (see Table 3-1 on page 70).
Use the special function command
Resistance. The range goes to the resistance power-on state (1k
Resistance, NPLC = 10); it does not change with the previous
command. NPLC remains at 10 PLCs providing resolution of 1m
The special range commands do not affect other functions except in the
