Power Source 9V alkaline battery (6LF22)
Battery Life 140 hrs continuous operation or 10,000 one minute measurements
Battery Indicator When Green LED starts blinking, remaining life is approx 8 hours;
When LED is OFF, the battery needs to be replaced
(1): Peak factor PF = Vpeak/Vrms
(2): The residual noise affects the measurement uncertainty according to the formula:
(I measured x 0.01)

I measured
global uncertainty =
(I measured ≠ 0)
If the current measured is zero, the uncertainty is equal to the residual noise.
