Page 3: １．Safety Warnings
１．Safety Warnings Make sure to read through this instruction manual before using this instrument. ●The instrument has been designed, manufactured, and tested according to: IEC 61010, pollution degree2, CAT．Ⅲ, 300V IEC 61010, pollution degree2, CAT．Ⅱ, 600Ｖ This instruction manual contains warnings and safety rules which must be observed by the use to ensure safe operation of the instrument and to retain it in safe condition. - Page 4 Following symbols are used on the instrument and in the instruction manual. Attention should be paid to each symbol to ensure your safety. Refer to the instructions in the manual. This symbol is marked where the user must refer to the instruction manual so as not to cause personal injury or instrument damage.
- Page 5 CAUTION ●Make sure that the function selector switch is set to an appropriate position before making measurement. ●Be sure to set the function selector switch to the “OFF” position after use. When the instrument will not be use for a long period of time, place it in storage after removing the battery.

Page 13: ５．Operation
５．Operation ５−１ Preparation (1) To Check battery set the function/range switch (5) To the desired position. If the display is clear without symbol “B”showing, battery voltage is sufficient. If the display blanks or“B”is indicated, replace the battery in accordance with the battery replacement procedures as described in section 6. - Page 14 CAUTION ●Transformers jaws , especially their tips, have been precisely adjusted to obtain maximum accuracy. Take sufficient care to avoid shock, vibration or excessive force when handing the instrument. ●When a foreign substance is stick in the jaw tips or they cannot properly engage, the transformer jaws do not fully close.
- Page 15 Note：When measuring large current, observe the time limit specified in section 3, Specifications. Otherwise, the transformers jaws may overheat, resulting in damage to the instrument. ― 13 ― GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com...

Page 16: ５−３ How To Use Peak Hold Function
５−３ How to Use Peak Hold Function 10ms or 100ms response time can be selected for peak hold measurement. Make selection according to your application needs. (1) With the transformer jaws clamped onto the conductor under test, slide the peak hold switch from the OFF position to the desired peak response time position. - Page 17 Note 2：If it is necessary to read the display away from the conductor in a peak hold measurement, press the data hold switch (2) first and then remove the instrument from the conductor. Otherwise, the peak hold reading may be higher than the actual value due to the electrical noise caused by the opening and closing of the transformer jaws.

Page 18: ５−４ How To Use The Frequency Selector Switch
５−４ How to Use The Frequency Selector Switch KEW SNAP 2413F has a very good frequency response because of the electromagnetic property of its transformers jaws. Therefore, it measured, AC current not only of fundamental frequency of 50Hz or 60Hz, but of high frequencies and harmonics superimposed on the fundamental frequency. -
Page 19: ５−５ How To Use Data Hold Function
５−５ How to Use Data Hold Function Push in the Data Hold button to freeze the reading. This is especially useful for taking a reading in a dimly lit or hard-to-reach locations. The display can be observed away from the conductor. Push the button again to release the reading. - Page 20 ― 18 ― GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com...

６．Battery Replacement Replace the battery when B symbol appears on the LCD display. (1) Set the function/range switch to the OFF position. (2) Unscrew and remove the battery compartment cover from the rear of the case. (3) Install a new 9V battery of type 6F22 or equivalent observing correct polarity. -
Page 22: ７．Cleaning
７．Cleaning Use a damp cloth detergent for cleaning the body of the instrument. To avoid possible deforming or discoloring, do not use solutions containing solvent. CAUTION ●Never use paint thinner, benzene or other solutions containing solvent for cleaning the instrument. Otherwise, deforming or discoloring of the instrument body may result. -
