100:1 probes are commonly used to measure higher voltages. Such probes have a 100 MΩ impedance and thus divide the measured voltage by a factor of 100 when used with Moku:Lab's 1 MΩ inputs. This enables Moku:Lab, with its +/- 5V input range, to measure much higher voltages.
Moku:Lab's Oscilloscope incorporates a probe scale factor to display the measured signal with the correct scale; tap on the 'Probe' scaling factor and enter "100x". This will then correctly scale the measured voltage.
Below we see Moku:Lab's Oscilloscope measuring US main voltage of 120 Vrms at 60 Hz.
