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.

Self-calibration: the sensor probe can automatically calibrate the zero point, automatically eliminate the system error introduced due to the zero point and drift, ensure the accuracy of each measurement, and at the same time eliminate the cumbersome verification each year.
Fast gas saving: After the boot into the measurement state, the determination time of each SF6 gas exposure point is about 2 min.
Self-locking joint: the original German imported self-locking joint, safe and reliable, no leakage.
Data storage: Large-capacity design, can store up to 200 test data.
Curve function: The large screen curve shows the dew point measurement process.
The display is clear: the color LCD directly shows dew points, microwater(ppm), ambient temperature, environmental humidity, time and date.
RS232 interface: Can be connected to the PC serial port for data transmission.
Built-in power supply: built-in 4Ah rechargeable lithium battery, enough to work continuously for 10 hours at a time.
