  • Page 6: Safety Information

    2. SAFETY INFORMATION 2-1. Safety Requirements This meter has been manufactured and tested in accordance with IEC 348 and DIN57411/VDE0411 Part 1: Safety Requirement for Electronic Measuring Apparatus, Safety Class II. This manual contains information and warnings which must be observed to assure safe operation and maintain the meter in safe condition.

  • Page 7: Safety Warnings

    2-3. Safety Warnings 2-3-1. To prevent electric shock hazard and/or damage to the meter, do not measure voltage exceeding 1000V DC or 750V AC. 2-3-2. To avoid damage to the meter and/or injury, observe the input limits as stated in Table 1. 2-3-3.

  • Page 8: Preparing For Operation

    3. PREPARING FOR OPERATION 3-1. Installing the Battery Your meter requires a 9V battery for power. The symbol appears when the battery voltage drops to certain limits. For proper operation, replace the battery as soon as possible. Continued use with a low battery will lead to abnormal readings.

  • Page 9: Using The Test Probes

    3-2. Using the Test Probes Use only the type of test probes supplied with your meter. These test probes are rated for 1200 volts. Cautions: • Although the replacement test probes are rated for 1200 volts, the maximum rating of your meter is 1000 volts DC and 750 volts AC. If you try to measure DC voltages above 1000 volts or AC voltages above 750 volts rms, you might damage your meter and expose yourself to a serious shock hazard.
