Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20℃ +68.
2) The set pressure range is the settable pressure range for Set Value 1 (P-1) and Set Value 2 (P-2).
3) The settable range is the settable pressure range for Set Value 3 (P-3) and Set Value 4 (P-4). It caters to the auto-reference function and is much wider than the rated pressure range.
4) The auto-reference function acts only on Set Value 3 (P-3) and Set Value 4 (P-4) of Comparative Output 2.
