1. Installation and Operating Conditions
1.1. This equipment should be placed in a room with good ventilation, shading, and cool conditions.
The equipment and walls must be more than 10 cm away. Do not place flammable or explosive
materials around it.
1.2. When the equipment is used for the first time, there may be slight fumes and odors due to spray
and rust-proof coating. This does not affect the use, it will disappear after one or two uses. Therefore,
it is best to open the doors and windows for a while when using for the first time.
1.3. The power box should be in accordance with the specified voltage and be reliably grounded to
ensure safe use.
1.4. Do not place excessively indoor objects. Space for air convection must be allowed to facilitate
hot air circulation and discharge of humid exhaust gas.
1.5. When the door is opened or the item is put in for a long time, the temperature setting should be
lowered or the power switch should be turned off for 5 to 10 minutes (depending on the length of the
door opening time) to reduce the occurrence of temperature and avoid unnecessary loss.
1.6. In order to maintain the appearance of the equipment, please do not use acid or alkali and other
corrosive materials to wipe the surface, the box can be cleaned regularly with a dry cloth.
1.7. The fuse box of the equipment is equipped with a fuse. If the equipment is not energized, first
check whether the fuse tube is in good condition. Please cut off the power when checking and
replacing the fuse tube. And replace the same type of fuse tube.
1.8. The oven doesn’t have explosion-proof function, do not put flammable and explosive substances
in.
1.9. Please turn off the power after using.
2. Product Structure
2.1. External material: cold-rolled steel with anti-bacteria powder coating.
2.2. Stainless steel inner chamber, round angle structure, adjustable shelves.
2.3. Double-layer glass observation window, adjustable airtight buckle lock.
2.4. PID microprocessor intelligent temperature controller.
2.5. Over-temperature protection.

The upper row of digital tubes displays the measured temperature, and the lower row displays the set
temperature
Press the SET key shortly, the temperature setting state will be entered
The parameters can be corrected by the▼, ▲ keys, press the SET key to enter the time setting state
Adjust time by After the▼, ▲ keys, after confirm, return to normal display screen.
AT (temperature auto tuning)

7
It need to re-adjust the temperature if the temperature fluctuations is more than 5 degrees, or can’t
meet the requirements of the temperature.
For example:
After setting the required temperature of 100 degrees, press the button 5 seconds, AT indicator
is on, then enter the auto tuning state. Can’t open the door or pump, can’t reset, can’t shut off the
power in this process. The meter will automatically calculate the heating rate. AT indicator will be off
after 30 mins. the instrument will control the temperature according to new program and in order to
achieve high precision temperature control.

Description:
1) Through press   or < key, revise parameters rapidly，The necessaries being over affirms
modification according to set key, Otherwise invalidate. Think that Lock is 0, Only when SC/
SCK is parametric may revise; Think that Lock is XXXX，Except SC /SCK, all parameters may
revise.
2) SC is process value biasing, SCK is process value sloping. May amend the measurement error
that cause from sensor to other arouses. Be in appearance when not having been amended
(SC=0;SCK=1.000), While zero position error of appearance is bigger may adjust SC,SC=
Standard value －Measure value; While full degree error of appearance is bigger may adjust

8
SCK,SCK= Standard value / Measure value.
3) P for setting proportional band. When take place regular oscillation of controlled temperature, the
proportional band should be increased and if controlled temperature drifts irregularly we ought to
decrease the proportional band.
4) I for setting the integral time. When the system takes place regular oscillation ought to I for
setting proportional band. When take place regular oscillation of controlled temperature, the
proportional band should be increased and if controlled temperature drifts irregularly we ought to
decrease the proportional band. ncrease integral time and if the system controlled can not remove
the static deviation in a long time ought to decrease the integral time.
5) D for setting the derivative time. Increasing the derivative time can decrease the overshoot of the
system.
6) T is Control Period, Relay output ≮20s,SSR and thyristor output≮3s continuous output,1s.
7) AL1 is alarm value 1, Measure value giving an alarm after deflecting setting value ∣AL1∣℃,
AL1 is set up giving an alarm for being to reach the end point at 0， Upper limit alarm for AL＞0,
low Limit alarm for AL＜0.
8) At the regular time function option parameter ET is 0，No regular time function，Time sets up a
menu concealing；ET is 1 or 2，Demonstrate time setting up menu ST. If ST is 0, Do not mind
time then, ET is 1, After the electricity on the instrument, Reckon by time beginning, ET is 2,
While the temperature reaches setting value start timing. Adopt countdown way at the regular
time, Begin to reckon by time， the upper row displays the Remain in time value， Reckon by time
being over, the upper row displays STOP， Run stoppage， Export a cutoff, Have intermittent buzz
sound prompting at the same time, Push down any key but noise reduction. After press start/stop
key over 3 seconds, Can start or stop procedure work.
9) dP is that the temperature is sure to change option , dP is 0 , temperature display has no point,
dP is 1 , temperature display has point.
10) Pr is Upper limit constant temperature power percentages, Generally, The function big or
preserving heat if systematic power allocation is prejudiced is very good, Pr value responds to
small, Can prevent from rushing the temperature; Whereas Pr value responds to then big, Can
improve litre of temperature speed. One system is different generally in different setting up under
the temperature from P , I , D parameter that adjust reaches, Suggest setting up temperature
adjusting parameter being able to reflect system inertia nearby in the room temperature, But be
used for the high temperature litre of temperature is possibly slower time end, Effect adjusting Pr
value now being ok to make system can reach very good controlling within entire range.
