4.2.4 External trigger
BUS trigger: use RS232C or USB bus control to trigger the instrument.
EXT trigger: use START signal pin in HANDLER interface to trigger the instrument.
4.3 Limit Operations
Limit operations set and control the values that determine the HI / IN / LO status of subsequent
measurements. Limits can be applied to all measurement functions except continuity. The limit test is
performed after percent math operations. Unit prefixes are applied before the limit test, for example:
Low Limit = -1.0, High Limit = 1.0
A 150mV reading equals 0.15V (IN).
Low Limit = -1.0, High Limit = 1.0
A 0.6k
Ω
reading equals 600
Ω
(HI)
You can configure the multimeter to beep or not when readings are outside of the limit range.
