The standard sequence of the experimental operation of the walk-in high and low temperature test chamber

 The walk-in high and low temperature test box has a wide range of applications in daily laboratory tests. First of all, we can turn it on by the user’s power supply. After turning on the walk-in high and low temperature test box, some operating procedures and steps need to be followed The instructions for the relevant models of walk-in high and low temperature test chambers are for operation. Before operating the low-temperature impact test chamber, it is necessary to understand the principles of the walk-in high and low temperature test chamber in order to better perform the operation experiment on the instrument.

  Before operating the walk-in high and low temperature test chamber, first turn on the user's power supply and then turn on the power supply. The location is on the side of the control cabinet. After waiting for 60 seconds, check whether there is a phase sequence alarm. Turn on the cooling water pump power switch, and then turn on the cooling water inlet and outlet switches (check whether the drain switch is closed before opening), 1 Observe the readings of the water inlet water pressure gauge and the water outlet water pressure gauge after minutes. The water pressure should be between 0.2~0.6Mpa, and the pressure difference should be greater than 0.2Mpa, and the water temperature should not be greater than 28℃. If humidity operation is required during the test, It is necessary to turn on the power switch of the humidifier and the water pipe switch, set the test parameters on the operating panel of the incubator, and then set the over-temperature protection operation test box. If an alarm occurs in the middle of the test, it should be dealt with according to the fault alarm handling in the "Installation and Maintenance Manual".
