Notes on the use of kinematic viscosity tester
1. Before use, it must be reliably grounded. When the glass cylinder is not filled with water, it must not be powered on. 2. The bath liquid in the bathtub shall be free of impurities and floating objects to avoid blocking the test hole. 3. The interval between restarting the instrument and using it is more than 15 minutes. The instrument can only be used after 45 minutes when it is started in a cold state. 4. When using a full immersion thermometer to calibrate the temperature, the effective scale of the thermometer shall not expose the liquid level of the constant temperature bath

Precautions for high voltage digital megger
High voltage digital megger consists of medium and large scale integrated circuits. This meter has high output power, high short circuit current and multiple output voltage levels (each model has four voltage levels). The working principle is that the DC voltage generated by the battery power supply in the machine through DC/DC conversion goes from level E to level L through the tested object, thus generating a current from level E to level L. After I/V conversion, the divider completes the calculation and directly displays the measured insulation resistance value on the LCD
