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.
O : Circuits which are not directly connected to the mains power supply.
CAT II : Electrical circuits of equipment connected to an AC electrical outlet by a power cord.
CAT III : Primary electrical circuits of the equipment connected directly to the distribution panel, and feeders from the distribution panel to outlets.
CAT IV : The circuit from the service drop to the service entrance, and to the power meter and primary overcurrent protection device
(distribution panel).
O: Device which is
not directly
connected to the
mains power supply

５．Preparation for Measurement
５−１ Checking Battery Voltage
① Set the function selector switch to any position other than "OFF".
② When the display is clear without "BATT" showing, proceed to measurement.
③ When the display blanks or "BATT" is indicated, replace the batteries according to section 8: battery replacement.
NOTE
● It is possible that display is kept in blank while the function selector switch is set to a position other than "OFF". This is due to sleep function which automatically powers the instrument down in a certain period of time after the last switch operation. To operate the instrument in this case, set the switch back to the "OFF" position, then to the desired position, or press any button.
５−２ Checking Switch Setting and Operation
Make sure that the function selector switch is set to the correct position, the instrument is set to the correct mode and the data hold function is deactivated. Otherwise, desired measurement cannot be made. (See section
6 for measurement instructions and section 7 for notes on functions.)
̶ 11 ̶
６．Measurement
６−１ Current Measurement
WARNING
● Do not make measurement on a circuit above 750V AC. This may cause shock hazard or damage to the instrument or equipment under test.
● Transformer jaw tips are designed not to short the circuit under test. If equipment under test has exposed conductive parts, however, extra precaution should be taken to minimize the possibility of shorting.
● Do not make measurement with the battery compartment cover removed from the instrument.
● Do not make current measurement with the test leads connected to the
V/ Ω and COM terminals.
● When measuring current is not less than 1000A, make sure to stop measurement within the maximum measuring time shown below.
Otherwise, transformer jaws may heat to cause a fire or deformation of molded parts, which will degrade insulation.
1000 〜 1500 Ａ：15min. 1500 〜 2000 Ａ：５min.
● Keep your fingers and hands behind the barrier during measurement.
