THZ-CInstructions for using an air constant temperature oscillator:
2Place the sample bottle firmly into the spring clip
3Power on:
Turn on the main power switch (on the right side of the body) and press the power button on the control panel
4Parameter settings:
A.Time, temperature, and speed settings:
press modify/confirm button Press again▲to3The instrument enters the parameter setting state. Press the parameter function key,▲▼Adjust the required parameter values, and once they reach the set values, press' modify 'to proceed/Confirm with the confirm button
B.Cooling coefficient setting (improving temperature control accuracy):
press modify/Confirm key, press again▲to9Press the cooling status button again, and the instrument will enter the cooling coefficient setting state,▲▼Adjust the cooling coefficient,After reaching the set value, press to modify/Confirm with the confirm button

Principles for setting refrigeration coefficient:
a.If the instrument needs to operate at ambient temperature plus 4 ℃ -60 Constant temperature state within the range of ℃,The refrigeration coefficient should be set to'2'To lower the temperature threshold,The ventilation cover on the back of the instrument should be removed,And turn the rotating window to the open state. Feeling the temperature rise too slowly during autumn and winter seasons,The ventilation cover can be opened after the temperature reaches the set value.
b.If the instrument needs to operate in 4 ℃ - ambient temperature plus 5 Constant temperature state within the range of ℃,The refrigeration coefficient should be set to'0.5',And close the ventilation cover.This work status starts the automated frost program
5run:
Press Start/Pause button: The instrument starts working. During the operation of the instrument, press'start/pause'key,The rotation of the tray can be paused.
6Shutdown:
Press the power button on the control panel2In seconds, the display screen disappears
Turn off the main power switch
7Sampling, cleaning debris, and stains

Maintenance, upkeep, and precautions:
Continuous cooling of instruments10Heating and moisture removal treatment for the day
To ensure the cooling effect, the condenser is cleaned once a month
Regularly check the fixing screws of the flask clamp to prevent noise or fixture detachment
