1. Introduction
FS9952_LP1 is a high performance, low power consumption and 3½ digits (1999 Counts) Analog to Digital
Converter that built-in the microprocessor (ADC+MCU). It includes the 8 bits microprocessor, low noise and
high stability OPAMP, AC rectifier OPAMP, voltage promotion and regulated voltage power, high regulated
bandgap, auto measurement switch and function control circuit, buzzer driver circuit, clock oscillation circuit,
backlight display control/driver circuit, LCD display driver circuit and so on.
With the microprocessor, FS9952_LP1 can do the logic function control when goes through the I/O ports.
By using the codes of MEA1～MEA4 pins, it can assemble various measurement functions, as well as
construct fully auto measurement meter and fully manual measurement meter through the code settings. For
the settings of Range, Select, Manual Hold, Max Hold, BLCTR and Power ON/OFF keys, you can act the
measurement mode select, function switch, reading hold, backlight display, power on/off and so on functions by
triggering these keys.
FS9952_LP1 has the AC/DC and ℉/℃ power on first select function that is decided by SELECT1 status.
This is for the convenience of user to enter the required measurement mode during power on.
With regard to the auto power off function, when there is no action within 15 minutes on the switch or keys
of the meter, the system will enter the sleep mode automatically to save the power. If it is not necessary to use
the auto power off function in the process of using the meter, it can be cancelled during using.
FS9952_LP1 is made by large integrated circuit technology so that rise greatly up the reliability of the
product, and make the design be simple and the volume be small. With small operating voltage and low power
consumption, it is convenient to use the power supply of battery, especially suitable for the use on the palm
mode meter.
FS9952_LP1 is truly a microprocessor-embedded and multifunctional measuring ADC so that just less
external components added, it can be a high accuracy, lots functions and low cost measuring meter.

3. User Development Function
FS9952_LP1 is a microprocessor-embedded ADC with the development system. Users can self-define the
functions of the meter according to their needs, as well as compose and revise the software for new
development to make it has different functions and style to suit the applications of themselves.
