Master M830B Meter: How to Check Li-Ion 3.7V, 1450mAh Camera Battery Status - Settings & Parameters

It's two sentences for you, it's magic for me.
I have a new Master M830B meter
I bought myself batteries for a digital camera. I put on and nothing. Load, put and nothing.
I want to check it, I have the above-mentioned meter, but I do not know how to handle it and how to read the obtained measurement (zero practice and theory).
Before I "get it in my pocket" I would like to check the batteries if they are ok

The battery is Li-Ion 3.7V, 1450mAh.

What do I check - the intensity? tension? to check the batteries? assuming that it is loaded - it would be nice to get to know what you are doing ... and not to ruin it at the same time ...

What result should oscillate with a good battery?

I will be grateful for indicating WHAT PARAMETERS TO SET THE KNOB OF THE METER AND IN WHICH INPUTS insert the wires, according to the instructions on this page.

... The drawing shows all the markings.

The battery is probably marked (+) and (-)
Now just turn on the meter position DCV 20 and measure the voltage
as for the intensity - switch to the 10A position and the red cable of the meter in the 10A DC hole - in fig (5) black (-) of course.
that's probably all

Probably measuring the current in this way will damage the fuse in the meter (if it has one. If not, you will damage the meter). To measure the current, the ammeter must be connected in series between the source and the load.

greetings

only if a colleague will measure the intensity, this will be done by this akumlatorka and it will certainly affect his life. So I advise against measuring the intensity by connecting the meter leads to the battery

so the intensity will not measure? However, can it be checked somehow?
"connect in series between the source and the load" - I could ask for my simple, non-electric mind, what should I do ???

I tried with the voltage shows zero when I put it "dry" to the battery.
Probably because it is written to measure the voltage "turn on the power of the measuring circuit". So I have to put the meter when, for example, charging the battery in the charger or something?

Maybe there is a safe way to discharge the batteries?

Maybe in diffrent way. What kind of camera is it? Is the battery (battery) you bought the same as it should be in this camera? It is almost impossible for the voltmeter connected to the battery to read evenly zero. If this is the case, the battery has a short circuit, which qualifies it for a complaint. If it is slightly more than zero, it has been over-discharged, which may result in a decrease in durability, and even irreversible damage.
Again. What camera? What battery? What charger?

Greetings.

Olympus mju300 camera
battery / rechargeable battery PLi-12B
charger, probably some universal 350mAh (all set with Allegro) - shop

The charger is green with orange light.
Green means that there is electricity in it and after inserting the (weak) battery it should jump into orange and start charging until it charges and the green light is on, which means charging.

For me, after inserting the battery into the charger, right after the purchase, the green one burns non-stop, despite the fact that the camera does not burn.

Yes, for example, the meter in the DCV 20 position is 0.00 / -0.00, but the battery is not connected to any power source ...

Added after 25 [minutes]:

I did the same operation (voltage) on another Minolta XT battery and it jumped out 4.15.
Also, I do not know how to read it in relation to this battery that I just bought where nothing moves and is all zero ??
One more thing. Can such a battery / its value in the measurement (0.00) damage the camera?

By the way, what does this value of 4.15 on the second battery mean? Is it ok? The battery is a 3.7V 750mAh lithium-ion battery, the original Mionolta ...

If a colleague measured the voltage on the contacts of a different battery, but of the same type, and the result was 4.15, it means that this battery is good. However, the one that shows 0.0, I would rather advertise.

if there is a voltage of 4.15v on the 3.7V battery, it means that it is charged and the latter either has discharged and requires charging or is damaged, although the second version is more reliable for me

Rather, no battery will show zero. Try to advertise is probably included.

If any battery shows 0V it is rubbish. In this case, advertise.

Batteries should always be checked under some load, i.e. with a resistor. As long as checking with a meter
will directly give you an indicative assessment, but you can be fooled. The voltmeter has a high resistance
in order not to disturb the tested system. Battery measurement on open contacts shows
voltage as it would be when connecting a ~ 100 Mega ohm resistor, i.e. with a negligible load.
If we connect the battery with a resistor selected so that the current is close to what it is in
a good battery - powered device and we will measure the voltage, then we will be able to judge
battery condition. Measuring the voltage with a good battery will show a value close to the nominal value. Bad measurement
even one that seemed good when measured with open contacts, will show a significant voltage drop
with a tendency to further decline. Battery manufacturers provide characteristics of voltage drop over time
at load with different values of resistors.
