IV. Operational Approach

1. After unpac king the inst rument, car efully remove the pac kaging, an d

chec k whethe r the instrument accessories are com plete and fr e e of

da m a g e agains t the instrument packing li st.

Not e : If the instrum e nt accessories are not complete or th e accessories are

da m a g ed, plea se contact our co m pany as soon as possible.

2. Place the low-tempe r ature ba t h and hi gh-temperature bath on the le ft

an d right sides of the control box, and add an ap propriate am ount of

medium; put the input refrigerat o r (cold he a d) into th e low-temp er ature

ba t h an d fix it; connect the respect ive load pl ugs to the i r corr e sponding

sock ets.

Not e : The medium in the constant te mperature bath must be higher than

th e heating tube to avoid dry heating of the heating tub e .

3. Insert the measuring cyli n der contai n ing the sample in t o the me asuring

cylinder fix ture and fix it, then plug th e rubber plug with the fo am head rod

an d the measu ring cylind e r tightly, an d connect the fo u r ai r nozzle s on the

control box with the foa m head rods respec t i vely. .

4. Tur n on th e power sw itch and the stirring swi t ch, an d then turn on the

swi t ch of the inp u t refrigerator and the gas source switch. When the

te mperature reaches the set tempe r a ture point, pe r form the test accordi n g

to the standard requirements. The valve can be ad justed to contr o l the gas

fl o w by adj u sting the four flow meters.

5. Afte r the test is over, the switch of the input refrigerator and the air

source switch should be cut off, and then the main engine stirring and

po w e r switch sh ould be cut off.

V. Use of temperature control meter

After the instrum ent is powere d on, the upper digital tube of the digital

di splay tempe r a ture control meter disp l ays the main control temperature

meas urement value, and the lower di g ital tub e di splays th e main control

set value.

If the upper row shows OVER, it means the sensor is open or the inpu t

signal exceeds the measurement range.

Set value change method

Pres s th e key, the up p er row di splays SP. Press th e ▲ or ▼ key

to make the lower row display the required va lue. Press ag ain

or go to standard mode.

Con t rol parame t e r change me thod

Pres s the key for more than 4 se c onds, th e upp e r row dis plays

th e prompt of the cont r o l param eter, and press the ▲ or ▼ key to mak e

th e lower ro w display the requi red value. Co ntinue to press the key, the

up per ro w wi ll displa y the pr ompts of ea c h parameter in turn, pr ess th e

▲ or ▼ key to make each control par a meter the required value. Press

th e key for mor e than 4 se conds to retu r n to the standa r d mode.

(It wil l automatica lly return to the st andard mode after 1 mi nute

without ke y press)

After pressing the ▲ key for 8 seco nds, the AT light flashes , and the me ter

star ts auto-tuning. After the auto-tuning is finished, the AT li ght goes out to

ob t ain a set of PID parame t e rs with a faster temper a ture rise . The meter

controls ac c ording to th e new PI D parameters.

After pres sing th e ▼ key for 8 seconds, the AT light flashes, and th e

in strument star ts aut o - tuning. Af ter the auto-tuning is fi nished, the AT ligh t

go es out, and a set of PID parameters that can overcome the

ov er-te mperature is obtaine d. The inst rument controls accord ing to the

ne w PID parameters.

Th e new PI D parameters can be checked on the inst rument.

During the aut o - tuning process , press the ▲ or ▼ key for 8 sec onds an d

th e n the AT light will go ou t , the auto-tuning will be ter m i nated, and th e

meter will co ntrol acc ording to the original PID param eters.

VI. Use of timer

When timing is needed, adjust the chronograph to the timing state and press the

"timing" button.

Timer operation: ①Turn on the "timing" button on the right side of the timer panel, and

the screen displays numbers. ②Set the time period switch according to the time required

for the test (the one with a horizontal line under the English letter is the countdown time

period switch, such as S, h, etc.). ③Press the "timing" button on the right side of the panel,

the timing is cleared, and there is no display on the screen; press it again, the button pops

up and the timing starts. ④After the timing is over, the buzzer will alarm.

VII. Fault analysis and Troubleshooting

Under normal circumstances, turn on the power switch, the power indicator light is

on, and after starting up, if the above process is found to be abnormal, it can be

analyzed and handled according to the following situations:

VIII. Precautions

1. Th e instru m ent should be placed in a ventilated and dry place . Keep the

in strument clean. Pay attenti o n that the elect ric contr ol part should not

en t er water or get we t .

2. The ground wi re shou ld be connected before use, and often che ck

whe t h er the grounding is go od.

3. When ins t alling, pa y specia l attent i o n to han d le with care to prevent

collision.

4. Never energize wh e n there is no med ium in the bath.

5. The tilt of the drop -in refri gerator should not be gr eate r th an 45 degrees .

6. It is strictly forbidden to sta r t the input refrige rator freque ntly. It must be

tu r n ed on again after 30 minutes after each sh utdown.

7. Since the refrigerator and the cold head are co nnected by a stainless

steel hose, th e r e is an insu l ation tube on th e outer ja cket of the ho se.

Ple ase pay attention when un pac king and in stalling: do not push, pull,

sque e ze or forcibly tw ist the hose, and it is stric t l y prohibi ted to hit the

ev aporat o r to avoid re f rigerant lea kage. The minimum bend i ng radius of

th e hose shall not be les s than 100 mm.

8. Wh e n the instrument br eaks down, you sho uld ask ex perien ced

pr o f essionals to repair it or notify our co mpany, and do not disassemble it

at will.

9. The warr a n ty pe r iod of this instrum ent is one year.
