    User’s Manual Edition, 2018 2018 Copyright by Prokit’s Industries Co., Ltd. © 1. General Information This digital multimeter is designed and manufactured in compliance with IEC-61010 safety requirements on electronic measuring instruments and hand-held digital multi-meters. It is compliant with IEC-61010 requirements pertaining to CAT IV 600V, CAT.
  • Page 3 * The meter is prohibited from being used in the vicinity of any explosive gas, vapor or dust. * The measurement must be made with correct input terminals and functions and within the allowable measuring range. * To prevent the meter from being damaged, the value to be input shall not exceed the extremes allowed by each measuring range.

  • Page 4: Safety Symbol

    * When appears, the batteries must be replaced immediately. The low level of a battery will result in incorrect reading on the meter, which is likely to bring electric shock or personal injury to the operator. * In measurement, category III voltage and category IV voltage shall not exceed 1000V and 600V respectively.

  • Page 5: Input Protection Measures

    * The designated replacement parts must be used at the moment of maintenance. * The operator must cut off all relevant power supplies before opening the meter. At the same time, the operator must avoid damage to the meter's elements by ensure that he himself doesn't carry any static. * The meter can only be calibrated, repaired and maintained by professionals.
