1: Refer to Appendix 1 for the reference resistance values of the platinum temperature-measuring resistors.
2: Use the following expression to calculate the theoretical value of the digital value.
Digital value = User range settings offset set value
3: Use the following expression to calculate the theoretical value of the digital value.
Digital value = User range settings gain set value
4: There are two identical areas consecutively. (Buffer memory addresses 160, 161 both have the 3-wire type CH. 1 Industrial shipment settings offset input
values.) Set the same value in each area.
(Example) The following values (theoretical values) are set when user offset/gain adjustment is made at the
offset set temperature of -180
temperature-measuring resistor connected.
