IZ7007  
Circuit for electron pedometer - ergmeter  
Short characteristics  
Functions performed:  
- 5 functions for counting time and calendar with indication of hours, minutes, seconds,  
month, date ,  
- count the quantity of steps by means of evaluation and counting pulses from external  
sensor ;  
- count and indication of steps, calories, kilometers , miles during current day and night  
(mode «DAILY STEPS COUNTER»);  
- summing up at changing 24 hours, steps , calories, kilometers , miles with values  
stored previous ( mode «TOTAL STEPS COUNTER»).  
Features:  
- imbed in chip element of quartz generator with operating frequency of 32768 Hz,  
capacity, resistor, and voltage doubler;  
- operation from one battery with the voltage of 1.5V, low consumption power;  
- availability of circuits of contacts bracing suppression on buttons inputs;  
- frequency of registered pulses from external sensor at counting steps is no more than  
6Hz at duration of time between the end of previous and beginning of counted pulse no  
less than 100 ms;  
- conversion of quantity of steps into calories , kilometres and miles according to the  
following ratios:  
(10 steps  
= 0.24 calorie  
= 0.0073 klm  
= 0.0045 mile ;  
1000 steps = 24 calorie  
= 0.73 klm  
= 0.456 mile );  
- indication of distance in miles and kilometers starting from 0.001, calories, starting  
from 0.1.  
Operating temperatures range  
operating temperatures range from -0 to +70°С.
