Instrument operating instructions and matters needing attention

⑴The instrument must be reliable grounding, power entrance lead into AC220V power.

⑵Open tank cover, and take out the test cell, we should shut the tank cover, when heating and testing the dielectric loss.

⑶The cover is protective and when you open it, will interrupt the heating and high pressure.

⑷During the test, there is high pressure and high temperature. Do not contact the test cell, cable and socket when the power is electrify and testing.

⑸Take care in order to avoid sprinkling the oil into the slot of test cell and the top panel when injecting and discharging oil.

⑹If it appears dead stop faults phenomenon while testing, turn the system back on, and restart the instrument.

Use the appropriate power supply cables.

Only use the product-specific power supply line in accordance with the product specification. Be right to disconnect and connect.

The instrument must be adequately grounded.

In addition to the power line grounding conductor grounding, product shell’s grounding columns must be grounded

In order to prevent electric shock, the grounding conductor must be connected with the ground.

Before connecting with the input or output terminals of the product, make sure that the product is properly grounded.

Note that rating value of all terminals.

To prevent fire or electric shock hazard, please note that all rating values and markings in the product.

Before connecting this product, please read the product manual in order to further understａnd the information about rating values.

Use the appropriate protective tube.

Use only the protective tube in accordance with provisions of this product type and rating.

Do not operate when there is any suspicion of failure. If you suspect this product is damaged, please contact our repair staff to check, and do not continue the boot operation.

Align the locating slot when the internal electrode into the external electrode.

Do not operate in humid environments.

Do not operate in explosive environments.

Keep the surface clean and dry.

Special notice: This instrument has high voltage output, improper use can compromise personal safety, prior to the use of this instrument, be sure to read the instruction manual carefully!
