ADLINK ND-6018 - Manual (Page 97)

Data Format and Input Range • 89
Two’s complement hexadecimal: CD27<CR>
((-2/5) x 32768) = -13107.2 = CD27H
Example 3:
• Input Range is ±10 V
• Input is +4 Volts
Two’s complement hexadecimal: 3333<CR>
((4/10) x 32768) = 13107.2 = 3333H
Example 4:
• Input Range is Type K thermocouple (range 0 °C to 1000°C)
• Input is 406.5 °C
Two’s complement hexadecimal: 3408<CR>
((406.5/1000) x 32768 ) = 13320.2 = 3408H
