How do I read this?

[DUBER]

For context, I'm trying to measure the current from my E scooter hall effect sensor. 

I believe my sensors work off binary as in one hall effect sensor is on at any one time. Rather than analogue. 

Idk if I'm reading the current measuring device right, but I think it's giving me around 4.8v or 4.9 for the main power cables.

Looks like that is on the 4.8 volt mark to me. Since you are on the 10 VDC range you should be reading the 10 VDC scale obviously, so you are reading it correctly.

@DUBER those first two are slightly less, they look closer to 4.6, but it could be the angle of the picture? I primarily looked at the last one. Doesn't sound like your measurement is that critical.

Well, you are NOT measuring current (uA, mA, or A) right now.

You are measuring voltage (mV, V, etc).

 

Since you set the scaling to 'DC' and '10V' then you read the 0 ~ 10 set of numbers, and the "middle?" scale.

It is reading 4.2V.
Red is for AC voltage, black is for DC voltage.

If you want to measure voltage, you connect the + and - wires in parallel.

 

If you want to measure current, you connect the + and - wires in series.

Voltage, not power.

Whoops, brain moving faster than the fingers.

Good catch.

thank you so much! @-rascal-

i'm going to try again but measure the current now!

Wait, can I even measure current. I'm so confused now why does AC.v work?

Depends on how your E-scooter is wired to work.

Make sure you are measuring the correct part of the circuit.

 

Just an example (because I don't own an E-bike or E-scooter):

 

If your E-scooter is anything like what is in the video, the DC input, is used to power a three-phase motor.

As a result, you will get AC readings on the output side.
