三. Temperature adjustment：

1. SV:  set temperature value

2. PV: the actual temperature value 

3. Δ:  increment key

4. Δ: decrease key        

5. Δ : Shift key

6. SET: Process setting key                            

Note: 

(1) In the set state, PV window shows the setting character, SV window shows the current setting value;

(2) If you want to enter the second setting area from the normal control state, you must press the SET button for more than 5 seconds;

(3) If you want to exit from the second set area to the normal control state, there are two ways: The first approach is to press the SET button for more than 5 seconds to exit; the second method is not according to any function keys of the instrument more than 30 Second, the system will automatically exit the second setting area. But the two methods are different from the exit: the first way to exit the second set area you set or modify the parameters are valid, according to the second method to exit the second set area, you set Fixed or modified parameters are invalid.

(4) In the second setting state, when OUT1 = 1, press the SET button for more than 5 seconds, the system will exit the second setting state, and automatically enter the auto-tuning optimization state, then OTU1 indicator light flashes;

(5) In the self-tuning work state, press the SET button, the system will exit the auto-tuning state, enter the set state. If you want to return to the auto-tuning state, you can set OUT1 to OUT1 = 1 again

And then press the SET button for 5 seconds to exit;

(6) When you want to prevent others from modifying your parameters, you can set the LOK value to 01 or 02 in the second setting area before exiting.

* Instrument function key Description:

SET  key: Process control key

Key: Set the bit shift key

Key: increment key

Key: decrease key  

Heating time to remind:

1. Time to remind the adjustment table, the middle of the red display is divided into: H (hour) M (minutes) S (seconds)

When the time set by H is hour, when M is set to time, the time set in S is seconds, the length of time can be set by adding or subtracting the above values. The longer the value is, the longer the value is. The shorter the time.

2. When the heating reminder time is set, press the start button, the reminder time starts counting, and the buzzer sounds the audible time.

Panel switch effect:The Increase /decrease temperature switch: turn on the total power to open the temperature switch, the device began to heat.

Total power switch: This switch is turned on after the machine power supply, this switch behind the machine.

四. On the self-tuning

(P). Derivative time (I), integral time (D) parameters are different for different temperature control objects, and PID control is used in most cases where the temperature control is very high. The traditional PID instrument, the above parameters are set by the experienced process control experts to operate the tuning, or most likely due to the parameters of the mismatch, resulting in the entire system out of control, which the majority of users to bring trouble. This series of instruments, with PID parameters from the auto-tuning function, start the function, it can automatically according to the control object, simulation expert operation automatically search, set the best parameters to achieve the best temperature control effect.

2. How to use the auto-tuning function

(1) Press the SET key to enter the second setting area, enter "Auto tuning setting status" according to the setting operation flow, set "OUT1" to "01", press the SET button for 5 seconds, the instrument will exit the setting State, into the auto-tuning state, then OUT1, When the indicator light is flashing, the "OUT1" indicator is off and the set P.I.D parameter is automatically saved in the instrument.

(2) If you want to check the setting of the P.I.D parameter, you can set it in the second setting area of the setting operation. (3) in the instrument self-tuning process, you must keep the power of continuous, and minimize interference, or you can restart the auto-tuning. (4) in the temperature control object initial heating process to start self-tuning and close to the set point (that is, the control point) to start self-tuning out of the two sets of parameters may be inconsistent, the general selection of a set of parameters is better. (5) In the case of large interference, it is possible to use the method of multiple setting to check the rationality of the parameters after the setting.
