Hysteresis: Even if the battery voltage rises, the status gauge will not increase
once it has decreased until the power is turned o󰀨 and on again.
A measurement cannot be taken when the status gauge is 0 (the measured
value will not be displayed).
(2) Live line warning display
Operation Displays the voltage between the + & − terminals and the measurement status
with the warning lamp on the MEASURE key.
This function works for all functions except when o󰀨.
