Page 5: After Use
especially when the voltage circuit bears the voltage of AC 100V or more ●It is strictly forbidden to use this meter to test the wire without any insulate protection has voltage exceed 35KV or convergence generatrix. ● In case that the voltage circuit to be tested bearing the voltage over 600V, the Tester shall be applied connecting insulating rod, with the hand holding on the fifth knot of it ●... -
Page 6: Introduction
Soft cloth (e.g. glasses cloth), moistened by clean, antirust and dehumidified lubricant (e.g. WD-40), instead of corrosive agent or rough issues shall be used to gently rub down the Tester ● In case that continuing use will cause safety hazard due to the performance of the Tester itself, stop using it and mothball it at once, then leave it to authorized organization for handling. - Page 7 The HV/LV high accuracy clamp ammeter can be used to measure the current and leakage current varying from 0.01mA to 1000A.HV clamp ammeter can also measure LV current. Current clamp: In order to make sure of the high accuracy, stability and reliability during perennial monitoring, special alloy is selected, latest CT technology and magnetic shield technology are adopted，which make sure almost resistance to external magnetic field.

Page 12: Switch Of Main Engine
2. Switch of main engine Press to start the engine, and LCD displays. After POWER the normal startup, the main engine will enter test receiving mode (see the picture above). The primary current is the testing data of high-voltage terminal while the secondary current the low-voltage. In case that signals are detected in both primary and secondary circuits, the main engine will show the transformation ratios on the basis of secondary circuit bearing current 5A, and indicate phase. -

3. Detection on HV current High voltage, very dangerous！Nobody but a qualified personnel after training could conduct operation on it. The operator should obey safety regulations; otherwise there will be the danger of electric shock resulting in personal injury or casualty. Only when all of the five insulating bars are connected can the high voltage line be detected, otherwise there may be the danger... - Page 14 by the high voltage detector which starts detection and feedback to the main set. Main set enter detection and data collection state after its normal starting up, If the main set receives the signal sent by the high voltage detector, there will be a live indication of current amount on high voltage end, If the main set fails to receive the signal sent by the high voltage detector, the first current is indicated to be”...

Page 16: Transformation Ratio Measurement
Clamp live wire and null line at the same time, leakage current could be detected.(note: total 2 wires) Clamp the earth wire, the leakage current could be measured(note: single wire) Clamp the main line, total current amount could be measured. (note: single wire) Where its numeral reading is not easily accessible, use high voltage detector to examine the current on low voltage wire. - Page 17 measured secondary current value is converted to be 5A, and then convert the first current based on that multiple, which is same with transformation ratio. Display【XXX/5A】 【Ratio】: The ratio between the first current and secondary current by actual measurement. 【 10kV-YYconversion ratio 】 : high voltage detector collects the secondary bus current, The ratio between transformer’s first current and mutual inductor secondary current could be...
