key
When the current positions are V
AC
, V
DC
, mV, mA, the Hz key invokes, in turn :
- frequency measurement,
- positive duty cycle measurement (% +),
- negative duty cycle measurement (% -),
- positive pulse count (
)
- negative pulse count (
)
- positive pulse width measurements (
)
- negative pulse width measurements (
)
A long press on Hz key allows a direct selection of the voltage or current function.

defined by the user.
Long press :
Adjusts the rate varying from 00000 s (a single transmission) up to 9h
