safely Make sure the instrument is turned off after use. Take out the battery, if the instrument is expected not to be used for a long time in future. Do not put the instrument in the harsh environment of sunlight, extreme temperature and humidity. Use wet cloth of water or neutral cleanser to clean the unit, do not use any abrasive or solvent. When the instrument is wet,make sure store it after it is dried. Note Do not use the instrument if there is any abnormal run of the instrument such as broken housing and test pin, or exposed metal parts. Do not shift the test range during operating after the test pin connected. Do not disassemble this instrument by the user, please contact our service department in case of need. Do not open the battery door or replace the battery when the instrument is wet and slippery, it must be dried with dry cloth. Turn off the instrument in case of opening the battery door or replacing the battery. Warning Do not operate under environment of flammable gas, the unit may generate spark during operation which may lead to blast. Do not connect the test pin if the operator has a wet hand. Do not apply any power supply that is above the allowed limit or test range of the instrument. Do not open the battery door during operation. Dangerous Warning Earthed Electrode Under Test Rx re Where earth for mains supply is used Supply Transformer Be sure to check earthed side of a commercial power supply. Secondary Side Primary Side Red Green E C P In this method, the terminal P and C has been short connected. This simple method can also be adopted to measure voltage with the green wire connected with V connector. Use volt meter to measure voltage of the common terminal to the earth, this instrument cannot be used to measurethat, it isvery dangerous, because uncertain state of theterminal and connecting wire, the voltage may not be displayed, which leads to electric shock or damage of the unit. This unit cannot be used to measure the common power voltage, this unit is not designed for this operation, when using quick test head to measure(measure earth resistance only), the termial P and C will be short connected which will lower the input resistance of the product. 4. In operation, press PRESS TO TEST key and turn it clockwise to LOCK position can perform measure without manual operation. 5. After measurement, turn the switch to OFF if the unit is expected not to be used for a while later. AR4105A

electric power net, as well as earth voltage test in the fields of household electric power system and electric appliance application. Dustproof and waterproof struture of the product meets IEC 60529, i.e. the unit can be used under very bad weather. Big sized LCD display and backlight Simple and easy operation, wide application. High precision and economical. Auto turn-off. -11- Special attention (1).In process of measuring EV, do not press PRESS TO TEST key, otherwise the unit is in wrong operation state, and LCD displays ERR. c.Switch the level switch to 200 and press TEST key, if the reading is too small, then switch in sequence of 20 /2 level, this time the reading is the EV value; in measuring resistance, press ing PRESS TO TEST will light on the state LED indicating the state of measuring. (note:1. if the resistance of the grounded pin is too big, “OL” or “----” will be displayed, check the test wires are properly connected or the pins are frimly inserted into the soil. 2.if the test wire has resistance, the value is difference between the readings and the resistance value of wire(0.04 ) at level 2 , while the resistance value of wire can be neglected at the level 200 and level 20 . Warning: the reading may be affected if the earth pin is distorted or smeared with other substance, so clean the pin before connecting the test wires; if the pin resistance is too big, error occurs. d. The unit will turn off automatically if there is no further operaion of the key after 8 minutes.Note: Turn the switch to Off position after auto trunoff, then turn to other level for next turn on. e. Backlight: it will be turned off automatically if there is no further opertion after 30 seconds. 3. quick measure(with provided quick wire): In case that it is not convenient to use the pin, set a subject that is lowly grounded as a polarity, for example metal gullet, water supply pipe, common ground terminal of power supply,ground terminal of buildings.

For earth voltageage measuring, do not apply voltagemore than 220V to avoid damage of the unit. For earth resistance measuring, do not apply voltage to the wire terminal 1. Measuring principle(as shown in figure) The earth resistance value comes from that bycalculation of the alternative current between terminal C and terminal E andthe potential difference between terminal E and terminal P in formula: RX=V/I 2. Precise measurement(with provided test wire) a. Pin the terminal P and C into earth and aligned with the ground device in spacing 5 to 10 meters between, and connect them as shown in the followng: (note: make sure the soil to be pinned is wet, water shall be injected if the soil is dry or sanded.)

1.Battery voltage check Turn on the unit, the LCD displays all info for once, and backligh is on, then return to the selected level, if the battery icon on LCD is “ ”, that means low battery, it is necessary to replace the battery with fresh one,otherwise the unit cannot work properly. 2. Connecting test pin: Insert the pin with clip into the corresponding connector in the unit, with terminal E to the green wire, P to yellow, and C to red; or connect terminal P and C with the quick test wire(for simple test);loose connection will affect the measure result 2 Operation instruction Before measurement Auxiliary Earth Spike Green Wire Yellow Wire Red Wire Simplified Test wire (red0) AR4105A
