2.6.2 Choose a point within the temperature control range of the product and set the SV temperature control value. When the PV measurement value is equal to the set value, keep it at a constant temperature (1～2) hours or so (depending on the product specifications, the constant temperature time may vary) , Observe that the difference between the actual measured temperature value of the standard thermometer and the measured value displayed by the controller PV should be ≤±0.5℃.

3. Operation steps

1) Temperature setting: Press the "SET" button once, the value of the SET window flashes, indicating that the temperature can be set as required, and the required temperature can be set through the "increase", "decrease" and "shift" keys. Press the "SET" key again to return to the standard display mode.
2) Timing function: Press the "SET" button twice, when the time is set to 0, there is no timing function; when the time is set to 0, the controller has a timing function, press the "SET" button, the TIME value flashes, indicating the time can be set as required. Use the "increase", "decrease" and "shift" keys to set the required time value. When the time is up, the TIME window displays the "END" buzzer, and you can press any key to silence it.

Note: ① Each time you modify a parameter, you need to press the "SET" key to confirm and the modification is effective.
② After setting all the parameters, press the "RUN/STOP" key and wait for about 3 seconds to start running.

4. Ways to improve the accuracy of temperature control

4.1 After the product has been used for a period of time, the temperature control accuracy should be checked according to the method 2.6, if it exceeds ±1℃, it can be corrected according to the following method:
4.1.1 Enter the parameter setting, find the symbol.

After the formula is calculated, it shall be modified on the basis of the original PK value at the time of delivery (Note: One correction is not accurate, and the correction can be repeated until it meets).

5. Function parameter table

In the standard state, press the SET key and the shift key at the same time for more than 3 seconds, the LCD screen displays the LK code, and you can enter the password setting level interface.
1)When LK is displayed in the output area of the LCD screen, press the plus or minus key or the shift key to make LK=0000, and press the SET key to enter the user parameter level setting.

Symbol	Name	Setting range	Description	Factory set value
tM	Setup of maxi temperature permissible by the instrument	full range	Stop heating beyond maxi temperature and give alarm.
Po	Boot mode	0～2	①When PO =0, after open the power, the controller in a stopped state, by long press star/stop key is up and running. ②When PO =1, after open the power, the controller will be running. ③When PO =2, running from last power began to run.
AL	Setup of alarm	0～100.0	When the temperature exceeds the value of SP+AL, the alarm light is on and the alarm is output (with HOLD function).
Pb	Zero adjustment (intercept)	-100.0～100.0	When the zero error of the instrument is greater and the full scale error is smaller, the value should be adjusted. As a rule with Pt100 the value is seldom adjusted.
PK	Adjustment of full scale (slope)	-1000～1000 S	When the zero error of the instrument is smaller and the full scale error is greater, the value should be adjusted. PK=4000 × (specified value－actual display value)/actual display value and as a rule with Pt100 the value is adjusted first.
PA	Onboard room temperature sensor correction	-30-30	When there is an error between the on-board room temperature sensor and the actual situation, adjust the value.
2b	The second zero correction	-100-100	When the second channel zero error is large and the full scale error is small, adjust this value. Generally, Pt100 rarely adjusts this value.
2K	Second channel full scale adjustment	-1000～1000	When the zero error of the second channel is small and the full-scale error is large, adjust the value. PK=4000× (mercury thermometer value-display value)/display value, generally Pt100 adjust this value first.

Table 2
※The products have been strictly tested before leaving the factory. When the technical indicators meet the requirements and work normally, no correction is generally required.

6. Usage of“ Over-temperature Protector” (optional)

The over temperature protector is a separate protection system. When the temperature controller encounters malfunction and causes temperature out of control and when the temperature in the working room reaches the set value, the overheat protector will cut off the heating and initiate the alarm.
(See Fig. below）working room temperature is lower than set temperature limit The protection system is released after set value and the meter is restored. Cycle repeats until problem is solved.
5.1 Set value is higher or equal to (SV+AL）+ （10～15）℃
5.2 See Fig. 6, Use ＋ and — button for over temperature setting on control panel.
To set desired temperature limit.
Example: SV=130℃, AL=10
Set the over temperature to 150℃.
