Description: 我用单片机8952和电压比较器339做了一个简单的电容容量测量表，参数大致如下：电容测量范围为1pF-9999.99uF，最小分辨力为1pF。分为5个量程，可以自动切换量程，也可手动切换。另外，有简单的频率计功能，能测量0-60MHz的数字信号频率（TTL电平）；还可以产生几个单点频率的方波信号（比如1KHz）。采用1602LCD作为显示器；4个按键控制；使用24C01保存当前设置值，不用每次开机重新设置。可单5V供电，也可9V交流供电 -I used the single-chip 8952 and the voltage comparator 339 to do a simple capacitance measurement table, parameters are as follows: capacitance measurement range 1pF-9999.99uF, the minimum resolution for the 1pF. Divided into five ranges, you can automatically switch range can also be manually switched. In addition, a simple frequency meter function, capable of measuring 0-60MHz frequency digital signal (TTL level) can also lead to several single-point-frequency square-wave signal (for example, 1KHz). 1602LCD used as a monitor 4 button control use 24C01 to preserve the current settings, do not reset each boot.

[Documents] CommunicatorP2C_Prospectus

Description: The P2C communicator is intended for remote readout of electricity meters on the level of industrial consumption according to the protocol complying to the IEC 61107 standard. It enables bi-directional data transmission from a meter to a data processing centre and vice-versa. The communicator is provided with two communication interfaces - one for the access to the meter, and another for data transmission to the billing centre. The communicator reads meters via CS interface (20 mA current loop by DIN 66348) or via RS 232 interface. Data are sent to the centre via various communication media (PSTN, ISDN, GSM or CaTV network). The SEP2W software enables parameter setting and readout of the communicators-The P2C communicator is intended for remote readout of electricity meters on the level of industrial consumption according to the protocol complying to the IEC 61107 standard.
