measure the voltage drop across certain resistor.
Press "CH1", or "CH2", or “CH3”, or “CH4” to choose target channel, then check "Measure Current On",
via or to set the A/V ratio (Amps/Volts ratio).
Amps/Volts ratio = 1/Resistor value.
vi. how to use automatic measurement
From Function menu, via , enter into "Measure" option.
When moving the mouse at the main display area, on the left, will appear, click it, the Measure menu
will hide; another click will show the Measure menu.
Automatic measurement available in 20 options under Measure menu. From the left-bottom of the main
display area, up to 8 measurement options could be accommodated.
All of 20 automatic measurement options go in Vpp, Vmax, Vmin, Vtop, Vbase, Vamp, Vavg, Vrms,
Overshoot, Preshoot, Frequency (abbreviated as “Freq”), Period, Rise Time, Fall Time, Delay A→B ,
Delay A→B , +Width, -Width, +Duty, -Duty.
The “Measure” option covers several useful functions -
Show All: When choosing Channel 1, or Channel 2, or Channel 3, or Channel 4 from "Show All", one
window will be called out, to show all of involved measurement values from Channel 1, or Channel 2, or
Channel 3, or Channel 4.
Add measurement: Check CH1, or / and CH2, or / and CH3, or / and CH4, or / and all of them firstly, the
measurement results will come in full details at the left-bottom of the main display area. Provided any/all
of the current 8 measurement options not the required, another 8 measurement options possible to add
for each channel. The new measurement option(s) will replace the current one(s) in the order of first till
last.
Note: The measurement results of both channels possible to come together.
Remove measurement: Uncheck certain measurement option (20 options in total) to remove it.
Mouse-click "Remove All" button to remove all of 20 measurement options.
