    14.4. ELECTROMAGNETIC COMPATIBILITY Emissions and immunity in an industrial setting compliant with IEC 61326-1. For electromagnetic emissions, the instrument belongs to group 1, class A, under standard EN55011. Class A devices are intended for use in industrial environments. There may be difficulties ensuring electromagnetic compatibility in other environments, because of conducted and radiated disturbance.

  • Page 95: Current Sensor Specifications (After Linearization)

    15.3.5. CURRENT SENSOR SPECIFICATIONS (AFTER LINEARIZATION) Sensor errors are offset by a typical correction inside the instrument. This typical correction, applied to the phase and amplitude, depends on the type of sensor connected (detected automatically) and the gain in the current acquisition channel used. The RMS current measurement error and phase error are additional errors (which must therefore be added to the instrument errors), indicated as influences on the calculations carried out by the analyzer (powers, energies, power factors, tangents, etc.).

  • Page 97: Maintenance

    16. MAINTENANCE Except for the battery and the memory card, the instrument contains no parts that can be replaced by personnel who have not been specially trained and accredited. Any unauthorized repair or replacement of a part by an “equivalent” may seriously impair safety. 16.1.
  • Page 98 Remove the cover. Figure 16-2 Tilt the top of the battery outward and remove it from its compartment. Figure 16-3 Disconnect the battery connector without pulling on the wires. The instrument retains the date-time function for approximately 24 hours without the battery. Spent batteries must not be treated as ordinary household waste.

  • Page 99: Memory Card

    16.4. MEMORY CARD The instrument accepts SD (SDSC), SDHC, and SDXC type memory cards. The card supplied with the instrument can store up to 8GB. (Note, however, that the maximum size of a trend recording is 2GB.) Before removing or inserting the memory card, ensure the instrument is disconnected and powered OFF. Write-protect the memory card when you remove it from the instrument.
