U, V and AUTO keys are used to set the measurement
range. AUTO key toggles ranging mode between “Auto”
and “Hold”. U and V keys are used to increase or
decrease the measurement range, if the current ranging
mode is “Auto”, then the ranging mode is changed to
“Hold” at the same time.
* Note：
When ranging mode is set to HOLD, the measurement
range is fixed at current range. Overload symbol “-----” will
be displayed if the impedance under test exceeds the
