Page 10: Safety Information
Safety Information Safety Information This instrument is designed to conform to IEC 61010 Safety Standards, and has been thoroughly tested for safety prior to shipment. However, using the instrument in a way not described in this manual may negate the provided safety features. Before using the instrument, be certain to carefully read the following safety notes.
Page 11 Safety Information Symbols on the instrument Indicates cautions and hazards. When the symbol is printed on the instrument, refer to a corresponding topic in the Instruction Manual. Indicates DC (Direct Current). Indicates the ON side of the power switch. Indicates the OFF side of the power switch. Indicates a grounding terminal.
Page 12 Safety Information Measurement categories To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as CAT II to CAT IV, and called measurement categories. DANGER • Using a measuring instrument in an environment designated with a higher- numbered category than that for which the instrument is rated could result in a severe accident, and must be carefully avoided.
Page 13: Operating Precautions
Preliminary Checks Before using the instrument, verify that it operates normally to ensure that no damage occurred during storage or shipping. If you find any damage, contact your authorized Hioki distributor or reseller. DANGER To prevent an electric shock, confirm that the white portion (insulation layer) inside the cable is not exposed.
Page 14 Operating Precautions Handling Cords and Cables DANGER If the insulation on a cord or cable melts, the metal conductor may be exposed. Do not use any cord or cable whose metal conductor is exposed. Doing so could result in electric shock, or other hazard. CAUTION The cord and cable are hardened under the 0 degree or colder environment.
Page 15 • When storing the instrument, make sure no objects that could short-circuit the connectors are placed near them. • For battery operation, use only the HIOKI Model Z1003 Battery Pack. We do not take any responsibility for accidents or damage related to the use of any other batteries.
Page 16 Operating Precautions Attaching the Strap CAUTION Attach the strap securely at 2 locations of the instrument. If insecurely attached, the instrument may fall and be damaged when carrying. Using SD Memory Cards CAUTION • Do not remove a card while data is being written to it. Doing so may damage the card. See “10.10 Removing SD Memory Card during Recording”...
Page 17: Turning On The Instrument
• If the power does not turn on, the AC adapter or the instrument may be malfunctioning or the power cord may be disconnected. Contact your authorized Hioki distributor or reseller. • If an error during the self-test, the instrument is damaged. Contact your authorized Hioki distributor or reseller. Using Magnetic Adapter...
Page 18 • To ensure safe operation, use only the voltage cord and current sensor specified by Hioki. Displayed values can frequently fluctuate due to induction potential even when no voltage is applied. This, however, is not a malfunction.
Page 19 • Keep discs inside a protective case and do not expose to direct sunlight, high temperature, or high humidity. • Hioki is not liable for any issues your computer system experiences in the course of using this disc.

Page 21: Overview
Overview 1.1 Procedure for Investigating Power Quality By measuring power quality parameters, you can assess the power quality and identify the causes of various power supply malfunctions. The ability of the instrument to measure all power quality parameters simultaneously makes this process a quick and simple one. The following is the description of the investigation process for the power quality.
Page 22: X84; Step 3: Checking Investigation (Measurement) Locations (Collecting Site Data)
Procedure for Investigating Power Quality (4) What is the expected cause? • Abnormal voltage RMS value trends, waveform distortion, transient overvoltage • Abnormal current Leakage current, inrush current Step 3: Checking investigation (measurement) locations (collecting site data) Collect information (site data) from as many locations as possible to prepare for the investigation. Check the following: (1) Wiring (2) Declared input voltage...
Page 23 Procedure for Investigating Power Quality Configure the conditions and events required for recording. If the EVENT indicator on the screen (p. 32) frequently changes to red, too many events have occurred. When the number of events reaches 9999 during recording/measurement, subsequent events will not be recorded (trend recording continues).
Page 24: X84; Advice For Identifying The Cause Of Abnormalities
Procedure for Investigating Power Quality Advice for identifying the cause of abnormalities  Record voltage and current trends at the power circuit inlet. If the voltage drops while the building’s current consumption rises, the likely cause for power abnormality lies inside the building. If the voltage and current are both low, the cause is likely to lie outside the building.
Page 25: Product Overview
Product Overview 1.2 Product Overview The PQ3100 Power Quality Analyzer is a measuring instrument used to manage power quality and identify abnormalities of the power line to analyze the cause of the trouble. All parameters can be recorded simultaneously. Trends and power abnormalities (events) of all parameters can be recorded simultaneously.
Page 26: Features
Features 1.3 Features Long-term event waveform Waveforms for up to 11.2 s when event occurs (1 s before event, 0.2 s on recording event, 10 s after event) can be saved for power abnormality analysis. DC (Direct Current) DC voltages can be measured. AC/DC Auto Zero Sensor allows DC current measurements measurements.
