  • Page 8: Safety Notes

    Safety Notes Safety Notes This meter is designed to comply with IEC 61010 Safety Stan- dards, and has been thoroughly tested for safety prior to shipment. However, mishandling during use could result in injury or death, as well as damage to the meter. Be certain that you understand the instructions and precautions in the manual before use.
  • Page 9 Safety Notes The following symbols in this manual indicate the relative impor- tance of cautions and warnings. Indicates that incorrect operation presents an extreme hazard that could result in serious injury or death to the user. Indicates that incorrect operation presents a signifi- cant hazard that could result in serious injury or death to the user.
  • Page 10 Safety Notes Measurement categories (Overvoltage categories) This device complies with CATIII (600 V), CATII (1000 V) safety requirements. To ensure safe operation of measurement devices, IEC 61010 establishes safety standards for various electrical environments, categorized as CAT I to CAT IV, and called measurement catego- ries.

  • Page 11: Usage Notes

    Follow these precautions to ensure safe operation and to obtain the full benefits of the various functions. Setting Up the 3290-10 • This meter should be installed and operated indoors only, between 0 and 40°C and 80% RH or less.
  • Page 12 Before using the meter the first time, verify that it operates normally to ensure that the no damage occurred during storage or shipping. If you find any damage, contact your dealer or Hioki representative. Before using the meter, make sure that the insulation on the probes is undamaged and that no bare conductors are improperly exposed.
  • Page 13 Usage Notes • The maximum continuous-input limit is obtained from the tem- perature increase due to self-heating during measurement. To prevent damage to the clamp-on sensor, do not input a current exceeding this limit. • The maximum continuous-input limit varies depending on the clamp-on sensor and the frequency of the current to be mea- sured.

    2.1 Attaching the Strap 2.1 Attaching the Strap Using the 3290-10 with the strap attached improves operability. Fasten the two straps together into one. Attach each end to the 3290-10 as shown in the figure above.

  • Page 35: Connecting Power

    • Handle and dispose of batteries in accordance with local regulations. Remove the batteries when operating from external power. When the batteries are installed, the 3290-10 will turn on even if the polar- ity of the external power is reversed, damaging the meter. • The indicator appears when battery voltage becomes low.

  • Page 36: Connecting The Ac Adapter (Optional)

    (such as with new batteries), the batteries power the meter until battery voltage decreases, at which point operation switches to the AC adapter. Connecting the AC Adapter Confirm that the 3290-10 is turned off. Remove the dust cap over the AC adapter jack, and plug in the AC adapter securely.

  • Page 37: Using External Power

    2.2 Connecting Power 2.2.3 Using External Power • To avoid electric shock and short-circuit accidents when connecting the optional 2m external power cable, first be sure the meter is turned off. • The external voltage requirements are 8.4 to 15.6 V DC at 1.2 VA.
  • Page 38 • When using the external power, note that current of approxi- mately 3 mA is consumed regardless of whether the power switch of the 3290-10 is on or off. • While operating from the external power, the remaining battery charge indicator (bar graph) indicates the loaded output volt- age (about 6V) of the external power.

  • Page 39: Connecting The Clamp On Ac/Dc Sensor

    • When disconnecting the output connector of the clamp-on sen- sor from the 3290-10 sensor jack, be sure to hold it by the metal part and pull it upward. Because the connectors lock, pulling or twisting the cable can damage the cable.

  • Page 43: Basic Measurement Procedure

    Basic Measurement Procedure • To avoid short circuits and potentially life-threatening haz- ards, never attach the clamp to a circuit that operates at more than 600V, or over bare conductors. • Clamp sensor should only be connected to the secondary side of a breaker, so the breaker can prevent an accident if a short circuit occurs.
  • Page 44 • Be sure to read the instruction manual for the clamp sensor to be used before starting measurement. • The hall element is used for the detector of the clamp-on sen- sor. The hall element tends to drift with age or due to the ambi- ent temperature.

  • Page 64 4.3 Measuring Current Sensor Temperature Characteristics The 9691, 9692 and 9693 CLAMP ON AC/DC SENSORs employ a Hall-effect element for current detection.

Zero-Point Temperature Characteristics Because of the individual differences between Hall-effect ele- ments, the actual offset and rate of change cannot be specified.

    7.1 Cleaning Maintenance and Service • Calibration and repair of this meter should be performed only under the supervision of qualified technicians knowledgeable about the dangers involved. • If the protective functions of the meter are damaged, either remove it from service or mark it clearly so that others do not use it inadvertently.

  • Page 134: Repair And Servicing

    • If damage is suspected, check the "Troubleshooting" section before contacting your dealer or Hioki representative. • If uncertain whether the problem can be attributed to the 3290-10 or clamp sensor, request that both be repaired. • The minimum stocking period for replacement parts is five years after end of production.
