Appendix C
The HP E1312A and HP E1412A Multimeters were designed so the default
mode of operation will deliver high accuracy readings with a minimum of
programming effort. However, many applications require high-speed
measurements. This appendix discusses two topics:
1. special non-SCPI function (
, , and
R4 R5 R6
and
2. how to increase measurement speed where reduced reading accuracy
is acceptable.
The HP E1312A and HP E1412A Multimeter have special function and
range commands for
resistance ( FRES ) shown in the following table. ACV, ACI, frequency or
period functions are not supported with these special commands.

These special commands act like a
or range. The range command acts only on the current function. For
example, if the current function is
range command changes the
R2

DCI RES FRES
R2 setting, you must send the commands
