5.1.1 Voltage
Voltage measurement range of SPM90 is 2~1000V. Users should be noted
this to prevent saturation of internal measurement circuit, which may cause
inaccurate measurement.
Note: If “U ERR V” is displayed when voltage is over 50V, it means
that wires on port 1 and 2 are reversely connected.
