Sometimes people call this tool with the name megohmeter or megger.<\/span> When used as a voltage leak test (due to leakage of insulation) it requires a voltage of 9V supplied by 6 UM-3 batteries each producing a voltage of 1.5V.<\/span> Via DC to DC Converter voltage of 9V will be raised up to 1000V.<\/span> Test results can be read on two flow paths on a scale board.<\/span><\/p>\n

The upper groove is used for reading resistance measurement of resistance<\/i> from 0-2000 M\u03a9, lower groove is used to read the result of voltage measurement from 0-600V.<\/span> When measuring the voltage leakage, the ideal reading result on the papan scale board is infinity (\u221e), this means there is no leakage in the utilization of the utility voltage.<\/span><\/p>\n

a.<\/b><\/span> Getting Started<\/b><\/span>
\n 1. Before measuring the AC voltage check the meter’s designation on the scale board.<\/span> The needle must be at the zero or (\u221e) position.<\/span>
\n 2. If required by using a minus screwdriver (-), set the needle positioner in the zero adjustment<\/i> so that the needle on the scale board actually points to a zero.<\/span>
\n 3. Before making a measurement check the battery condition, set the left switch at B.CHEK<\/i><\/b> position, set the right switch in position M\u03a9<\/b> .<\/span>
\n 4. If necessary the battery can be replaced.<\/span>
\n 5. When measuring AC voltage never touch the tip of the investigator cable ( probes<\/i> )!<\/span> You can be stung by high voltage electricity.<\/span>
\n 6. When measuring AC voltage, battery is not needed.<\/span><\/p>\n

b.<\/b><\/span> Measuring Isolation<\/b><\/span>
\n 1. Make sure the circuit to be measured is in the “OFF”<\/b> position and not connected to the AC voltage source.<\/span>
\n 2. Set the left switch in the “ON M\u03a9”<\/b> position of the right switch in position “M\u03a9” POWER ON<\/b> Indicator will work.<\/span>
\n 3. Insert the high-voltage (red color) probes<\/i> cable into the jack<\/i> marked “M”<\/b> , the black probes<\/i> cable into the black holes (on the right of the hole marked “M”<\/i> ). .<\/span>
\n 4. Connect the black probes<\/i> cable (using the clip alligator) to the “common” or ground of the circuit to be measured.<\/span> For TV, connect to TV chassis.<\/span>
\n 5. Touch the investigator cable (probes) high voltage to the point to be measured (copper wire from the power cord for example).<\/span> In order to avoid electric shock, keep your finger position on the back of the safety.<\/span>
\n 6. Read the measurement results on the scale board.<\/span> Sometimes the measurement results are less satisfactory.<\/span> This occurs because the contact between the tip of the investigator cable ( probes<\/i> ) with the point to be measured is less than perfect.<\/span>
\n 7. If there is no leak in the insulation that wraps the power cord (or other electronic circuit), the needle will still point to infinity (\u221e).<\/span>
\n 8. If there is a leak in the insulation that wraps the power cord (or other electronic circuit), the needle moves to the right.<\/span><\/p>\n

c.<\/span> AC Voltage Measurement<\/b><\/span>
\n 1. Set the left switch in “OFF (ACV)” position<\/b> , set the right switch in ACV position.<\/span>
\n 2. Insert the investigator cable ( probes<\/i> ) into the ACV jacks<\/i> .<\/span>
\n 3. Connect the investigator cable ( probes<\/i> ) to the point containing the AC voltage.<\/span>
\n The measurement results are read on the scale board.<\/span><\/p>\n

d.<\/span> Safety and Safety Tool<\/b><\/span>
\n 1. Remember one thing!<\/span> High-voltage electric shocks can make a current of 10 milli-Ampere enter the heart and stop the heartbeat of humans.<\/span> DC and AC voltages below 35 Volts still contain a danger to humans.<\/span> High electricity is even more dangerous.<\/span><\/p>\n

2. The output voltage of the M\u03a9 mode can be up to 1000V, but the current that accompanies it is not large so it is not so dangerous, however Insulation Tester<\/i> contains high electric shocks, so never touch the tip of the probes<\/i> cable.<\/span><\/p>\n

3. If you want to improve the Insulation Tester<\/i> and open the case<\/i> , remember one thing that there may still be a voltage as high as 1000 Volts at the points of the circuit.<\/span> Some points may still contain large currents, as well as investigator cables ( probes<\/i> ) still contain high voltage, avoid direct contact.<\/span><\/p>\n

4. Do not use Insulation Tester to measure AC voltage above 600 Volt.<\/span><\/p>\n

5. When checking whether the leak insulation (resulting in a leakage), make sure the circuit to be checked is free from the power grid or other power source.<\/span><\/p>\n

Avoid direct contact with points in high-voltage circuits such as “ON-OFF”<\/b> switches, fuse, transformers, and so on.<\/span> At these points sometimes there is still a high voltage, although the plane to be measured has been turned off ( “OFF”<\/b> )<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
