1. The water bath should be placed flat on a fixed platform, the power supply voltage must be consistent with the voltage required by this box, the power socket should use a three-hole safety socket, and the ground wire must be connected before use.
2. According to the experimental requirements before the experiment, add an appropriate amount of clean or purified water to the water tank to the partition or higher. Then place the experimental vessel on the shelf and close the hole cover.
3. Turn on the power, put the power switch to the "ON" end, and turn the temperature "set-measure" switch to the "measure" end, the green light is on, the power supply is heating normally, then turn the temperature setting knob according to the desired temperature Set the temperature. At this time, "LED" displays the set temperature value. When the set temperature is higher than the water temperature of the water tank, the instrument starts to heat up. When the green light is on, the heater starts to heat. When the red light is on, the heater stops heating. The red and green lights alternately jump to indicate the constant temperature state. If you need to change the temperature, turn the setting knob at any time. When using, the temperature displayed by "LED" is the actual required temperature.
4. Turn the temperature "set-measure" switch to the "measure" end, the system automatically measures the temperature of the reagent in the water tank. At this time, the temperature displayed by the "LED" is the actual required temperature.
Water bath maintenance
1. When using the water bath, it must be reliably grounded, and water should not overflow into the control box.
2. Do not have no water or the water level is lower than the electric heating tube in the water bath to prevent the electric heating tube from bursting.
3. Carry out maintenance inspection of the instrument once a month, and fill in maintenance records in time.
Water bath cleaning
1. After each use, immediately clean the instrument, hang the logo, and fill in the use record in time.
2. After each use, put the water in the water bath clean, use a brush to brush away the coarse debris in the water bath, and clear the pot. Wipe the inner and outer surfaces of the water bath with a soft cloth, then wipe dry with a cleaning cloth.
3. Effect evaluation: There should be no water droplets on the inner surface of the equipment, and the outer surface of the equipment should be bright and clean without stains.
