Multifunctional mechanical scale with LCD display, watch communication tester, and watch repair tool (EU plug)

For conventional ST, the instrument can react automatically. For Special BE AN, you can select manually.
The instrument automatically calculates the velocity deviation, amplitude, and error, and displays them in real time based on the data. Select "±99.9s/d" in the item numbers for displaying results, which allows adjusting the rate deviation accuracy down to 0.1s/d.
The clock frequency diagram can be displayed on the LCD screen.
Depending on different clocks, the instrument automatically adjusts the optimal signal level during the test.
The sampling period can be selected as 2 seconds, 4 seconds, 8 seconds, 12 seconds, 20 seconds, 30 seconds, or 60 seconds, and the average value of the corresponding period is considered the exact clock value.
