Knowledge of precautions for the use of heating and cooling integrated machine

Wuxi Guanya heating and cooling integrated machine is a commonly used refrigeration, heating and temperature control system in pharmaceutical and chemical laboratories.
So, what aspects should be paid attention to when using heating and cooling integrated machine? 1.
Check before starting the power cord The plug of the power cord has been reliably inserted into the power socket, and the power cord is grounded reliably
.

2.
Temperature setting 1.
Turn on the power switch, all indicator lights and digital tubes are on
.

After about 5 seconds, the number displayed on the instant temperature display window (PV) is the instant temperature of the metal module, and the number displayed on the set temperature display window (SV) is the last used set temperature
.

2.
Press the (SET/SET) key once, and the number on the left of the setting temperature display window (SV) will flash.
Use the up and down keys to change the flashing number to the desired value
.

 　　3.
Press the (SET/SET) key again, the flashing digit moves to the right one place, and use the up and down keys to change the flashing digit until it reaches the desired value
.

 　　4.
Press the (SET/SET) key again, the flashing number moves one digit to the right, and also use the up and down keys to change the flashing number until the desired value to complete the temperature setting
.

Or press the (SET/SET) key again to restart the setting from the left
.

 　　5.
After the temperature setting is completed, the digital flickering phenomenon disappears, indicating that the local system enters the running state and operates according to the currently set temperature value
.

 　　3.
Precautions 1.
Before and after each use, use a cotton swab dipped in distilled water to clean the cone hole of the module to ensure that the test tube is in full contact with the cone hole wall
.

 　　2.
In the process of setting a new temperature, the local system still operates according to the last set temperature value, until the SV window stops flashing numbers
.

 　　3.
If the difference between the displayed temperature (PV) and the temperature measured by the third party is more than 0.
1℃, the custodian of the machine will correct the temperature error
.

 　　4.
During the use of the thermostat, do not press the (Calibration/ADJ) key
.

 　　5.
If it is used in the experimental operation at a constant temperature of 4 °C for more than 4 hours, the condensed water of the module must be removed
.

The method is: unplug the power plug to cut off the power supply, then unscrew the two black knobs on the module, take out the module, use a soft cloth to remove the condensed water on each contact surface, and then install and reset the module
.
