YES

If you are measuring current by probing the voltage

drop across a resistor, choose YES.

A/V (mA/V)

V/A (mV/A)

Turn the M knob to set the Amps/Volts ratio. The

range is 100mA/V ~ 1KA/V.

Amps/Volts ratio = 1/Resistor value

Volts/Amp ratio is automatically calculated.

Limit the channel bandwidth to 20MHz to reduce

display noise.

1. To set channel coupling

Taking the Channel 1 for example, the measured signal is a square wave signal

containing the direct current bias. The operation steps are shown as below:

(1) Press the CH1 MENU button to show CH1 SETUP menu.

(2) Press the H1 button, the Coupling menu will display at the screen.

(3) Press the F1 button to select the Coupling item as "DC". Both DC and AC

components of the signal are passed. The waveforms are shown as Figure

5-2.

(4) Then, press F2 button to select the Coupling item as "AC". The direct current

component of the signal is blocked. The waveforms are shown as Figure 5-3.
