Page 3: 1．Safety Warning
1. SAFETY WARNING Electricity is dangerous and can cause injury and death. To avoid possible electric shock, personal injury or damage of instrument, always treat it with the greatest of respect and care. If you are not quite sure how to proceed, stop and take advice from a qualified person. - Page 4 returned to your distributor for attention. 14. Do not operate the function switch while the instrument is connected to a circuit. If, for example, the instrument has just completed a continuity test and an insulation test is to follow, disconnect the test leads from the circuit before moving the function switch.
- Page 5 Measurement categories (Over-voltage categories) To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as O to CAT IV, and called measurement categories. Higher-numbered categories correspond to electrical environments with greater momentary energy, so a measuring instrument designed for CAT III environments can endure greater momentary energy than one designed for CAT II.

Page 12: 5．Continuity (Resistance) Tests
This measurement should not include the resistance of any test leads used. The resistance of the test leads needs to be subtracted from any continuity measurement. KEW 6010B is provided with a continuity null feature which allows automatic compensation for any test lead resistance. - Page 13 4． Release the test button. Press the test button and ensure the display reads zero before proceeding. While using the Continuity null function, " " appears on the LCD. The null value will be stored even if power off the instrument. The memorized null value can be cancelled by disconnecting the test leads and pushing the AUTO NULL SWITCH with the test button pressed or locked.

Page 14: 6．Insulation Tests
This charge must be removed from the system at the end of the test, a function which is automatically performed by KEW 6010B. If an alternating voltage is applied between the conductors, the system continuously charges and discharges as the applied voltage alternates, so that there is a continuous alternating leakage current flowing to the system. -
Page 15: 6． 1． 3 Conduction Current
6． 1． 3 Conduction Current Since the insulation resistance is not infinite, a small leakage current flows through the insulation between conductors. Since Ohm's Law applies, the leakage current can be calculated from applied voltage (V) Leakage current (μA) = insulation resistance (MΩ) Fig 5 6．... -
Page 16: 6． 2 Damage To Voltage Sensitive Equipment
The system is charged to the full test voltage, and will be dangerous if left with this charge. KEW 6010B provides an automatic path for discharging current as soon as the test button is released to ensure that the circuit under test is safely discharged. -

Page 19: 7． Loop Impedance Tests
○ Even though the test current in the 2000 ohm range (15mA test current) is low some RCD's may trip due to sensitivity or where there may already be additional leakage in the circuit being tested. ○ The Loop impedance in a TN system is small and therefore it is not recommended to test in the 2000 ohm range. -

Page 28: 8． 7 Testing Time Delayed Rcd's
OPERATION OF THIS TEST. Note: ● KEW 6010B calculates the Uc voltage with the impedance measured, and if the calculated Uc voltage exceeds UL, KEW 6010B indicates the warning "UcH v" on the LCD and stops the measurement. If the value is less than UL, the unit proceeds with the measurement of a RCD. -
