If you are using this product for the first time, please pay attention to the following items:

When the instrument is turned on, it automatically enters the measuring state. At the beginning of the measurement, the flow valves on the panel are opened completely, and then the flow is regulated by the needle valve of the measuring pipeline on the instrument. When the measurement is completed, the operation is reversed.

The equipment has built-in large capacity lithium battery, which can work continuously for more than 10 hours after being charged.

When the dew point meter is not used for a long time, there will be some air left in the test pipeline and chamber. Therefore, during the first test, the high humidity gas in the dew point meter will affect the test speed, because the moisture in the air needs to be taken away before the SF6 gas is saturated. So we will find that when we test the second SF6 electrical equipment and measure it later, the speed will be very fast (3-5 minutes).

When printing data, it is recommended to plug in AC220V power supply to increase battery life (printer selection).

In case of high temperature, we suggest that the time of measurement should be arranged as far as possible when the temperature is lower in the morning, because the higher temperature will affect the accuracy of measurement.
