How to read a digital multimeter

When viewing the measurement results of the digital multimeter, how to get the correct reading is to multiply the reading by the gear multiple, and the unit is ohm.

Take the VC9808A+ multimeter as an example:

Resistance file (Ω) (same for other models)

1. The maximum display value of the 200Ω gear is 200Ω (indication value 150.1=150.1Ω). Note that the indication value of short-circuiting two test pens should be subtracted.

The maximum display value of 2.2KΩ gear is 2KΩ (indication value 1.1=1.1KΩ)

3. The maximum display value of 20KΩ gear is 20KΩ (indication value 15.1=15.1KΩ)

4. The maximum display value of 200KΩ gear is 200KΩ (indication value 156.1=156.1KΩ)

So on and so forth.

It is divided into 7 gears (200Ω, 2KΩ, 20KΩ, 200KΩ, 2MΩ, 20MΩ, 200MΩ) current gear (A) gear (AC-DC common gear, when using the black test lead is inserted in the COM hole, the red test lead is inserted in the mA hole, more than 200mA To be inserted in the 20A hole)

The maximum display value of 1.2mA gear is 2mA (display value 1.751=1.751mA);

The maximum display value of 2.20mA gear is 20mA (display value 17.51=17.51mA);

3. The maximum display value of 200mA gear is 200mA (display value 189.2=189.2mA);

4. The maximum display value of 20A gear is 20A (display value 17.51=17.51A).
