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 resistance value 1.51336
3: Use the following expression to calculate the theoretical value of the digital value.
Digital value = User range settings gain resistance value 1.51336
4: There are two identical areas consecutively. (Buffer memory addresses 160, 161 both have the 3-wire type CH. 1 factory default offset 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 -200 and the gain set temperature of 850 with a Pt100 type platinum
temperature-measuring resistor connected.
