Command
Table 4-11 describes range and measurement rate commands and queries. In autorange
mode, the Meter automatically selects a range for each reading. In manual range mode,
the user selects a fixed range.
Table 4-11. Range and Measurement Rate Commands and Queries
Table 4-10. Function Modifier Commands and Queries (cont.)
Meter returns a numeric value indicating modifiers in use, where 1 = MIN; 2 =
MAX; 4 = HOLD; 8 = dB; 16 = dB Power; 32 = REL; and 64 = COMP.
If multiple modifiers are selected, the value returned is equal to the sum of the
values of the selected modifiers. For example, if dB and REL are selected, 40
is returned.
Meter enters the relative readings modifier (REL) using the value shown on
the primary display as the relative base. Autoranging is disabled. See
“Relative Readings Modifier (REL)” in Chapter 3 for more information.
Meter exits REL modifier and returns to the ranging mode and range selected
prior to selecting REL.
Meter enters REL modifier using <relative base> as the offset <relative base>
value.
<relative base> can be a signed integer, signed real number without
exponent, or signed real number with exponent. Autoranging is disabled.
If <relative base> exceeds the measurement range, an Execution Error is
generated. See “Relative Readings Modifier (REL)” in Chapter 3 for more
information.
Meter returns <relative base>. If the relative modifier has not been selected,
an Execution Error is generated.
Meter enters the autoranging mode on the primary display. If autorange mode
cannot be selected (if REL, MIN MAX or diode/continuity test is selected), an
Execution Error is generated.
Meter returns 1 if it is in autorange or 0 if not in autorange.
Meter exits autoranging on the primary display and enters manual ranging.
The present range becomes the selected range.
