Attentions

• For transformer with 19-step load tap switch, steps 9, 10 and 11 are tapped to the same value. The tester shall put in 17 for tap type. At this time, after step 12 is tapped, the tap position displayed on the tester is 2 smaller than the actual position.
• When error information is displayed, the power shall be turned off before clearing the error.
• Wires shall be connected well. The tester shall be earthed well!
• When the tester is in service, if the display on LCD screen is unreadable and there is no response after pressing "↑" and "↓", or the measured value is far different from the actual value, please press the Reset key or turn off the power, and then repeat your operation.
• If there is no character displayed on the screen or the color of character is very light, please turn the luminance potentiometer to an appropriate position. Luminance potentiometer is a multiturn potentiometer with 10 turns!
• Working place of the tester shall be far from strong electric field, strong magnetic field and high-frequency equipment. The smaller disturbance of electric power supply is, the better it will be, and electric power supply should use illuminating line. If distance of electric power supply is still relatively intense, AC clean power supply may be used to provide power supply to the tester, as long as the capacity of AC clean power supply is greater than 200VA.
• The tester shall be stored at a dry place with favorable ventilation. If it is stored for a long period or in a damp environment, the warm up time shall be prolonged to remove moisture before use.
