reading
e.g. at end of range the maximum crest factor is 4.5
Warning on the display when the crest factor is exceeded: i=
in the least significant digit.
Excluding ranging:
asynchronous start synchronous start
NM 08s 05s
HRM O7s 07s
Including ranging:
asynchronous start
synchronous start
Synchronous start means that the input signal and the start command
are given simultaneously (e.g, in EXT START mode).
