_____________________________________________________________________ Measurement categories (Overvoltage categories) To ensure safe operation of measurement product, IEC 61010 establishes safety standards for various electrical environments, categorized as CAT I to CAT IV, and called measurement categories. These are defined as follows. CAT I Secondary electrical circuits connected to an AC electrical outlet through a transformer or similar device.
_____________________________________________________________________ Notes on Use Follow these precautions to ensure safe operation and to obtain the full benefits of the various functions. This product cannot be used on following voltage lines. If the voltage exceeds, there will be a short-circuit DANGER accident or electrocution accident will result.
Page 10
_____________________________________________________________________ For model 9658 When conductors being measured carry in excess of DANGER the safe voltage level (SELV-E) and not more than 150 V, to prevent short circuits and electric shock while the clamp core jaw is open, make sure that conductors to be measured are insulated with material conforming to (1) Measurement Category III, (2) Pollution Degree 2, and (3) Basic Insulation Requirements for Working...

_____________________________________________________________________ 1.3 Measurement Value Recording Modes Effective value calculation To calculate effective value, measurement signal is sampled every 334 µs and operation is carried out from data with maximum 135 points to seek effective value. Maximum 135 points partitioned at complete cycle 334 µs Recording To record measurement value, calculate effective value per...
_____________________________________________________________________ 1.4 Leak Current Measurement Clamp the sensor on the conductor, so that the conductor passes through the center of the clamp core. For measurement of grounded leads, clamp the sensor on one lead only (see a). For overall measurements, clamp the sensor on the entire circuit path (see b).
Page 19
_____________________________________________________________________ If a strong current (on the order of 100 A) is flowing in an NOTE adjacent circuit, accurate measurement may not be possible. Perform the measurement at a sufficient distance from other current-carrying conductors. Do not input a current which exceeds the maximum continuous input rating.
_____________________________________________________________________ 1.5 Load current measurement Be sure to clamp only one lead of the conductor. Clamp so that the conductor is in the center of the sensor aperture. The frequency of special waveforms such as at the secondary NOTE side of an inverter can not be indicated correctly. When the current to be measured is unknown, begin measurement with the 1000 mA range selected.
_____________________________________________________________________ Chapter 2 Set Up 2.1 Replacing the Battery To avoid electric shock when replacing the batteries, first disconnect the connection cables from the object WARNING to be measured. During battery replacement, use caution not to put any foreign materials such as a metal object into the unit to avoid damage to the unit.
Page 22
_____________________________________________________________________ Installing new batteries ensures about one month of recording (when interval is set at 1 sec) and about 10 days of recording (when interval is set at 0.2 sec). (reference value with power save setting set to valid and at 20 ) Remaining battery power indicator ( ) indicates remaining battery life reducing incrementally from right.
_____________________________________________________________________ 2.2 Power Save Function Display window is automatically turned off in approximately 15 seconds after last key entry. (Sleep) However, while recording, REC/AV/ mark shows each conditions. Sleeping..Press any button to turn display on to display measurement value or to set settings. Note when interval setting display is on, sleep does not engage with no button press.
The 3638-20 measurement range is set at 100 mA, do not exceed 100 mArms. To avoid damaging the unit, do not use any other sensors except 9657/9658 CLAMP ON LEAK SENSOR as sensor connector.
