Your Question
What are the electrical measuring and what are they for?
This file answers all your questions. Meter, ammeter, voltmeter, etc.
Will have no secret for you.
The advantage of digital Multimeters as shown against is that they are self-protected and are not likely to "grilling" by mishandling of you (especially poor selection of ranges).
Guide positions rotary switch for the device presented
Unless indicated otherwise: black cord must be connected to the COM jack and the red test lead to V AΩ
(1) AC voltmeter (symbol V). Two ranges are present on this device:
- 200: to measure voltages from 0 to 199 Volts
- 500: to measure voltages from 0 to 499 Volts
The display is in Volts.
(2) DC voltmeter (symbol V =). With the following ranges:
- 200m: to measure voltages from 0 to 1.99 mV (view expressed in mili volts)
- 2: to measure voltages from 0 to 1.99 V (display in volts)
- 20 to measure voltages from 0 to 19.9 V (display in volts)
- Etc.
(3) Ammeter for direct current (symbol = A).
- 3 ranges of low values (2mA, 20mA and 200mA) are proposed for the measurement of DC currents is mainly used in electronics.
Ammeter for alternating current (symbol A).
- A single value range is proposed for this low-end device: 10A.
Caution: Use this position involves positioning the red lead into the 10A jack.Once the red cord is plugged into 10A and black lead on COM, your device acts as a short circuit, even if the rotary switch is in a "voltmeter" position. Plug it and a 220V outlet and you'll have a nice fireworks!
If you look closely at the photo (ref. (6)), you will notice that the cords are patched with tape because the son of the webmaster have melted as a result of manipulation of this kind.

(4) Ohmmeter (symbol Ω)
- 2M: to measure very strong resistance (from 20k to 1.99 MΩ)
- 200 k: to measure strong resistance (from 2 k to 199 kΩ)
- 2 kΩ: to measure the average resistance (20Ω of 1.99 kΩ)
- 200Ω: to measure the average resistance (from 2Ω to 199Ω)
- 200 k: to measure strong resistance (from 2 k to 199 kΩ)
- 2 kΩ: to measure the average resistance (20Ω of 1.99 kΩ)
- 200Ω: to measure the average resistance (from 2Ω to 199Ω)
- 
: used by electricians to test diodes
: used by electricians to test diodes
For home use all or nothing ("grilled" or "no toast") it is better to choose the positions 200Ω or 2 kΩ, but no more.
