Note 1: The instrument supports full universal input; however please select one of two codes, as an external receiving resistor (250Ω) is supplied for current input. If no external receiving resistor is required, a code 8 specification product can be used for current input.

Note 2: Scaling range: -1999 ~ 9999 Unit
Span: 10 ~ 10000 Unit

Note 3: When the 08 power supply code (24V AC/DC) is selected, the sensor power supply cannot be selected.
