Probe with a double-head design, model 038-BB-5.7L. The two ends of the needle are shaped differently, with one end being pointed and the other having a flat or rounded tip.

High-brightness yellow LED SMD 0805 components supplied by manufacturers. These are ideal for use as indicator lights in various electronic applications.

AVX TPSE226M035R0125 low-impedance tantalum capacitor, with a capacitance value of 22 µF. Known for its stability and reliability in high-performance circuits.

Electronic scale crystal oscillator, 3.2 x 2.5 mm (3225 package), 16 MHz (16.000 MHz), 12 pF, with tolerance options of 10 ppm, 20 ppm, and 30 ppm.

The instruction list and ladder diagram for the real arithmetic instruction application are shown in the figure below.

Instruction List:

LD I0.0

+R A C1, VD100

/R VD100, AC0

This set of instructions is commonly used in PLC programming to perform real number calculations. The "LD I0.0" command loads the input status, while "+R" and "/R" are used for addition and division operations on real numbers. These operations are essential in control systems where precision is required, such as in industrial automation or process control.
