Input impedance: About 1GΩ for mV range, about 10MΩ for
other ranges
Accuracy guarantee: 1%~100% of range; short circuit allows
least significant digit ≤5
Max input voltage: 1000V (if the voltage is >1000V, the red
indicator light will be on and the buzzer will sound an alarm; if
the voltage is >1010V , the LCD will display “OL”)
Overload protection: 1000V
