注意事項

1．在測量過程中一定不要接觸測試線的金屬部分，以避免被電擊傷。

2．測量接線一定要嚴格按說明書操作，否則后果自負。

3．測試之前一定要認真檢查設置的參數是否正確。

4．最好使用有地線的電源插座。

5．不能在電壓和電流過量限的情況下工作。

6．短路試驗時，非加壓側的短接必須良好，否則會對測試結果有影響。

7．做短路試驗時，如果高壓或中壓側出線套管裝有環形電流互感器時，試驗前電流互感器的二次側一定要短接。

8．試驗接線工作必須在被試線路接地的情況下進行，防止感應電壓觸電。所有短路、接地和引線都應有足夠的截面，且必須連接牢靠。測試組織工作要嚴密，通信順暢，以保證測試工作安全順利進行。

Attention should take 

1. Don’t touch the metal parts during the measurement test to avoid electrically damaging.

2. Wiring must be strictly measured by manual operation.

3. Be sure to carefully check before the test parameters set correctly.

4. Best to use a grounded outlet.

5. Do not limit the voltage and current in case excessive work.

6. Short circuit test, the non-pressurized side must be well short, or would affect the test results.

7. Do short-circuit test, if high or medium voltage side with an annular bushing current transformer, current transformer before testing the secondary side must be shorted.

8. Test wiring work must be grounded in the test line in the case, to prevent induced voltage electric shock. All short circuit, grounding and wire should have sufficient cross-section, and must be firmly connected. Test organization working to tight, smooth communication, in order to ensure the smooth progress of work safety testing.
