―――――――――――――――――――――――――――――――――――――― Introduction Thank you for purchasing this Hioki 9276 Clamp-On AC/DC Sensor. In order to use this product effectively and to ensure that it enjoys a long operational life, read this Instruction Manual carefully and then retain it for future reference.
When the unit is delivered, check and make sure that it has not been damaged in transit. In particular, check the accessories, core section, and sensor connector. If the unit is damaged, or fails to operate according to the specifications, contact your dealer or Hioki representative. ――――――――――――――――――――――――――――――――――...
If damage is found, contact your dealer or Hioki representative. ・ If there is any type of dust or dirt on the core contact surfaces, measurements may be affected.

―――――――――――――――――――――――――――――――――――――― Chapter 1 General 1.1 Product Overview When connected to the 3270 Current Monitor, this clamp- on sensor can output current waveforms without any need to cut the conductor being measured, simply by clamping the sensor onto the conductor. This equipment can thus be used in conjunction with a recorder, an oscilloscope, or other such equipment in order to record and measure current waveforms.

―――――――――――――――――――――――――――――――――――――― If the conductor being measured is not centered, the NOTE results may be affected by its position. (3) Confirm that the lever is completely locked. Accurate measurement is not possible if the sensor is not NOTE locked. ・ Do not exceed the maximum allowable current input. CAUTION The maximum input range differs, depending on the frequency of measured current.
