IMPEDANCE METER / FREQUENCY COUNTER **2A

Technical specification：

1、Power：AC **0V±*0%, *0Hz to *0Hz. For other specifications, please specify when placing an order.

2、Resistance／Impedance measuring range：

a、0 to **0 Ω , Resolution 0.1 Ω

b、**0 to 4K Ω, Resolution 1 Ω

3、Precision：DCR：≦±( 0.2% + 1 digit ) ; *：@******************** 0.4% + 1 digit ) ;

4、Frequency range of the built-in oscillator： *0Hz to 8KHz, continuous adjustable.

5、Dimension：*6 ( W ) × *6 ( D ) × *3 ( H ) cm.

6、Weight：4.5KG.

1、Model***2A can measure the voice coil DC resistance value of the loudspeaker, Headphone, and receiver, As well as the AC impedance value of the afore-mentioned products.

2、With its built-in frequency oscillator, Model***2A does not need to connect with an external signal generator, Instead it can be able to measure the AC impedance value of the pre-measured products.

3、Its built-in frequency oscillator has a frequency range from *0Hz to 8KHz, Which is continuously adjustable. ( It can also connect with an external frequency oscillator, To set the frequency value of the intended measured AC impedance value, a Frequency range from *0Hz to *0KHz is allowable.)

4、With Model***2A, users can preset their own qualified upper and lower limits, which are very suitable for speedy Q.C. in the production line.

5、Model***2A has 2 LCD digital display windows, which can display directly the impedance value and frequency value respectively.

6、It can serve as a frequency counter, which is used to test the output frequency of other frequency oscillators, measurement range of frequency： *0Hz to **0KHz.
