Thermistor setting Program
CM1-TH08A is used to measure the temperature by calibrating thermistor resister. Please refer to the manual of thermistor module”
Registering NEW Program
Select [ File – New program..], and input " Program Name"
Select the [OK] button.
Writing a thermistor program
Example of writing a thermistor program
After Registering NEW program, below the box appear.
Register " BASE" and " Slot " which set thermistor.
Setting Channels
Setting Tab: This is used to set "Status", " Digital Range" ,"Digital Filter", "Average OP" and "Device"
Drag a mouse, you can select many channels.
If you want only one channel, select a channel by clicking a mouse.
By using a ctrl-Key, you can select channels what you want.
Select "EDIT", below the box appear
Select or unselect the blank, "enable"
Check the blank "Enable", you can change values.
Digital Range : it is used to convert the max/min temperature to digital value by a temperature converting table.
Digital Filter : It is used to set up in case of hunting by outside noise for converted temperature.
It is restricted converted ranges before storing converted temperature.
Range of set value : 0 ~ 70 %
Example : Values which stored the buffer memory is present values by adjusting Digital Filter.
Present Value = Present value + (formal value – present value) * Digital Filter(%) / 100
Average : It is used to set up calibrating value for average times
Range of set value : 0 ~ 255 sec.
Device : It is used to store converted temperature in CPU memory.
Enable domain: X, Y, M, L, K, D
Type of stored data: °F, ℃, digital value
Example: If you set like above the box, you can store ℃ value in D100.
Table Tab : It is used to input the temperature, and resistance of a thermistor
Please register the values refer to temperature-resistance table by provided manual from thermistor cooperation.
Center P. temperature = Max. Temperature – (Max. Temperature – Min. Temperature) / 2
In case of inputting the temperature-resistance table incorrectly, converted temperature value is out of range (0.3%)
Example : Max. temperature = 100℃, Min. temperature = -20℃
100 – (100 - (- 20) / 2 = 100 – 60 = 40℃
Register temperature values (Max. = 100℃, Center = 40℃, Min. = -20℃), and then Input resistance values of each temperature
Resistance value is except for a decimal point
Cable resistance: It is used to settle a resistance of cable resistance.
