00.0Ω. When the leads are not connected the display w ill read infinity indicated by “OL”. This w ill ensure that test lead are under w orking condition. 2-4 Rotary Switch positions Turn the Tester on by selecting any measurement Lift ＜ 1000v,500v,250v,125v (4000MΩ) OFF 400Ω/BZ, 1000VDC,750VAC ＞ Right 2-5 Buttons and a display Indicators a). Button HOLD/MAX.MIN : Instant-pressing the “HOLD” button the 1st time, the current values will be hold in the primary display., but it will return in the 2nd pressing ; pressing 2 seconds ,it will enter directly into the “MAX”status, and one another instant-pressing will switch to the “MIN”, if instant-pressing once more, it w ill recycle ,but exit if pressing 2 seconds again. LOCK :In the insulation resistance testing function ,press the “LOCK” button ,and then push down the “ TEST” key, it w ill occur the high-voltage and enter the insulation resistance testing status. Press the “TEST” button once more ,it w ill shutoff the high-voltage and exit from the insulation resistance testing status. TEST : In the insulation resistance testing function ,pressing and holding the “TEST” button, The meter w ill bring high-voltage, and enter into the insulation resistance testing, being free from the “TEST” , it w ill cutoff the high-voltage and exit form the insulation resistance testing. ZERO/LIGHT :Iinstant-pressing the “ZERO/LIGHT” button in the 1st time, the current values in the primary display w ill be set zero,(mainly used for 400Ω, the low resistance testing), ,it will return

“LIGHT” status, and the LCD backlight light up. After 15 seconds, the backlight is shut off automatically, the same as pressing for 2 seconds within 15s. b) Display Indicators The Primary Display：Indicate the current function testing values The Secondary Display： It shows the output DCV while you test the insulation resistance, and the battery voltage w hile the ACV The Analog Bar：indicate the current function testing value in synchronous with the primary display. :While testing the insulation resistance, the symbol “ “ flashes frequently if the voltage is over 30V. •))) : While testing the insulation resistance, the symbol” •))) “ flashes frequently and the buzzer warns continually if the outside voltage is over 30V. the symbol “ •))) “ is indicated w hile LOΩ≤35Ω and the BZ w arns continuously. LOCK：Push down the “LOCK” button while you test the insulation resistance and the symbol “ ” is indicated. LOBAT：The display shows “LOBAT” when the voltage drops below 7.5V MAX/MIN:Stand for the maximum or the minimum. ZERO : Digital zero adjusting。 HOLD :The digital holding function for the primary display. AC，DC，:The indicator for the voltage property. V，MΩ，Ω The measured dimension units。

a)Turn the function switch from the “OFF” position to the left（4000 MΩ/1000V---4000/ MΩ500V---4000 MΩ/250V---1000 MΩ/125V）,and chose one of the voltage-block( there are 4 ranges namely, 4 MΩ40 MΩ400 MΩ4000 MΩ, can be sw itched automatically for every voltage-block.) b)Connect tw o testing lines to the tested； c)Push down and hold the “TEST” button /or press the “ LOCK” keystoke first and then the “TEST” button, if the tested is electriferous and its voltage ( AC/DC) is over 30V, it w ill refuse work and no high-voltage testing occurs, simultaneity, it shows “>30V” on the LCD, the symbol “ ” flashes, and the buzzer warns frequently. if the tested is diselectriferous or its voltage is low er than 30V, it will enter into the formal testing process and brings the high-voltage. on the primary display, the insulation resistance in MΩ is indicated in-phase w ith analog bar; on the secondary display, the tested insulation voltage in V (DC) is indicated, the symbol “ ” flashes and the buzzer warns frequently d)Being free from the “TEST” button or pushing down the “TEST” button in the “LOCK “ status can exit from the “LOCK” status and shutoff the high-voltage，synchronously, the resistance values is indicated in the primary display w ill be held, and the secondary display still be in the status of monitoring the insulation voltage for the tested. e)Subsequently, discharge the balance insulation voltage of the tested through the inner sw itch of the meter. Turning the function sw itch can exit automatically from testing status during the process。

MEASUREMENTS a). Set the range sw itch to 400Ω/BZ Position b). Connect the red test lead to the V Ω terminal and black to the COM terminal. c). Connect the tips of the test leads to both ends of the circuit under test. read resistance in Ω on the LCD. The two ranges(40.00/400.0Ω) can be switched automatically; the primary display of the resistance in Ω, flashes in synchronous w ith the analog bar. d). When the impedance on circuit is below approximately ≤35Ω.It w ill indicate by a continuous beeper. e) The current is from 200 to 220mA while the tested resistance is 0Ω f) The high voltage symbol “ “ flashes along w ith a primary display of “>30V” and the buzzer warns frequently if the voltage (AC/DC) is more than 30V. 5.AC/DC VOLTAGE MEASUREMENTS a). Set the range sw itch to ACV or DCV position b). Connect red test lead to “V Ω” terminal and black test lead to terminal “COM”. c). Connect test prods of test leads IN PARALLEL to the circuit being measured. d). Read the voltage value on LCD.

The meter w ill automatically enter the “sleep mode” if there is no function change or button press for 10minutes, but it w orks as soon as you turn the rotary function switch or push down any button. 7.POWER TOOLS AND AMALL APPLIANCES This test w ould also apply to other similar equipment that has a line cord. For double insulated power tools, the megohmmeter lead shown connected to the housing would be connected to some metal part lf the tool(e..g chuck,blade). Note: The sw itch of the device must be in the “ON” position and the main pow er should be disconnected. MOTORS AC-Disconnect the motor from the line by disconnecting the w ires at the motor terminals or by opening the main sw itch. If the main switch is used and the motor also has a starter then the starter must be held, by some means, in the “ON” position. In the latter case, the measured resistance will include the resistance of the motor, wire and all other components between the motor and the main sw itch. If a w eakness is in dicated, the motor and other components should be checked individually. If the motor is disconnected at the motor terminals, connect one megohmmeter lead to the grounded motor housing and the other lead to One of the motor leads. DC-Disconnect the motor from the line. To test the brush rigging, field coils and armature connect one megohmmeter lead to the grounded motor housing and the other lead to the brush on the commutator. If the resistance measurement indicates a w eakness, raise the brushes off the commutator and separately test the

megohmmeter lead to each of them individually, leaving the other connected to the grounded motor housing. The above also applies to DC Gemerators.

avoid errors due to leakage from other equipment. Check each conductor to ground and /or lead sheath by connecting one megohmmeter lead to a ground and /or lead sheather and the other megohmmeter lead to each of the conductors in turn. Check insulation resistance between conductors by connecting megohmmeter leads to conductors in pairs.
