further checking, or use a circuit breaker to cut off the power supply. Continuance of abnormal state
will result in fire caused by overheating.
9.The electric power supply must be cut off under following situations:
9.1.When opening the door of power box. Without cutting off power supply, the opening of the door
will probably result in electric shock.
9.2.When replacing the fuse. Replacing the fuse without cutting off the power supply will probably
result in electric shock.
9.3.When the malfunction occurs. Mishandling will result in the further damage of the equipment or
accidental injury.
9.4.When not using for a long period of time. The dust accumulated on the outlet may leads to fire
cause by electric leakage.
9.5.When moving the equipment. Moving the equipment connected with power supply will
probably result in electric shock.

Special attention:
The unit has a timer range of 1~999minutes. When the
time parameter is setted as 0 , the unit will keep
running constantly.
Simplified instruction on the setting of constant temperature control mode
The program can be set up to 10 temperature control segments; one ramp step and one hold step for each
segment, and can be run up to 99 times in cycle.
1. Stop the current operation by pressing the "R/H/S" button first; the indicator of "Run" goes off.
2. Press "Set", then press "Increase" and enter code "2", press "Set" again to enter the page of "Segment 1
Ramp Time" (RT). Then press 'Increase/Decrease' button to enter the desired value, and press "Set" again
to confirm. The "Ramp End Temperature" (RET) and "Hold Time" (HT) of each segment can be set in the
same way. (Each segment contains 3 parameter settings, "RT", "RET", "HT")
6.Setting of parameter under the constant temperature control mode 3. For the program with less than 10 segments, user should set a terminating point for the whole
program; simply press "Decrease" to set the "RT" of the followed idle segment as "end", then the
whole program terminates there. Otherwise, set it as "cycle", if repeat running of the whole
program is needed. For example, for a program with only two segments, after finishing setting the
"Segment 2, Hold Time", user should press "Set" to enter the page of "Segment 3, Ramp Time";
then press "Decrease" and set it as "End", if only once operation is needed, alternatively, set as
"Cycle" if multiple repeat operation.
4. Keep pressing "set" to skip the pages of the rest idle segments settings, and enter the page of
"hold segment deviation", enter the deviation temperature limit.
"Hold Segment Deviation (HSD)" is the temperature deviation limit for the condition of entering
the "Hold" step.
4.1. If "HSD" is set as "0", the program enters the "Hold" step on time priority, which means no
matter if the actual temperature reaches at "RET", the "Hold" step will be triggered as soon as the
"RT" dues.
4.2. If "HSD" is set as "N", (N>0), then the program will enters the "Hold" step on temperature
priority, which means the "Hold" step will only be triggered when the actual temperature reaches
at RET¡À N , no matter if the "RT" run out.

According to the diagrams shown above, In both cases of A and B, because of the power
limitation of heaters, it can only be heated up to 35 from 30 for the 5 mins of R1, still
5 lower than the "RET".
In Case A, it goes straight to the "H1"step,which includes another 5 mins to heat up to
40 , leaving the actual retaining time only 5 mins instead of the nominated, 10mins.
In case B, it will keep heating up to 39.9 (40 -0.1 ), and then the "Hold" step starts
for exactly 10 mins, which is 5 mins longer than that in Case A.
If it's the same situation in Segment 2, in Case A, the whole program runs 30 mins in total,
while 40 mins in Case B.
5. Press "Set" to enter the page of "Programme Parameter, Cycle", press
"Increase/Decrease" to set the times of repeat running of the whole program. The running
is to be repeated only if the segment setting ends with "Cycle" mentioned in 2.3.
6. Press "Set" again to finish setting of program control mode.
If a "Pause" of the running program needed, simply press "R/H/S", and
the "Run" indicator twinkles, and press it again to resume. To restart the
program, press the "R/H/S" and hold for 3 seconds to quit the existing
program first, the "Run" indicators goes off, and press "R/H/S" again to
restart the whole program.
Case B: HSD=0.1
