Читаю значение:

```auto
modbus_client --debug -mtcp 10.0.0.79 -a1 -t 0x04 -r 10
Connecting to 10.0.0.79:502
[00][01][00][00][00][06][01][04][00][0A][00][01]

<00><01><00><00><00><05><01><04><02><00><18>
SUCCESS: read 1 of elements:

```

Применяю scale 10:

Читаю, ожидаю значение в десятичные 10 раз больше:  
Получаю:

```auto
modbus_client --debug -mtcp 10.0.0.79 -a1 -t 0x04 -r 10
Connecting to 10.0.0.79:502
[00][01][00][00][00][06][01][04][00][0A][00][01]

<00><01><00><00><00><05><01><04><02><00><F4>
SUCCESS: read 1 of elements:
	Data: 0x00f4 

```

0x18\*10 ~ 0xf4  
Получил ожидаемое.
