    Safety Summary The following safety precautions apply to both operating and maintenance personnel and must be followed during all phases of operation, service, and repair of this instrument. Before applying power to this instrument: • Read and understand the safety and operational information in this manual. •...
  • Page 3 You must ensure that each accessory you use with this instrument has a category rating equal to or higher than the instrument’s category rating to maintain the instrument’s category rating. Failure to do so will lower the category rating of the measuring system. Electrical Power This instrument is intended to be powered from a CATEGORY II mains power environment.
  • Page 4 • In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or finely-divided particulates. • In relative humidity conditions outside the instrument’s specifications. • In environments where there is a danger of any liquid being spilled on the instrument or where any liquid can condense on the instrument.

    before touching any internal parts. Verify the voltage-sensing device is working properly before and after making the measurements by testing with known-operating voltage sources and test for both DC and AC voltages. Do not attempt any service or adjustment unless another person capable of rendering first aid and resuscitation is present. Do not insert any object into an instrument’s ventilation openings or other openings.

  • Page 23: Ratio Setup

    Menu 2.13 Ratio Setup This setting has the effect of scaling the measured value of the current and voltage. For example, a 116V signal becomes 232V when the “Voltage Ratio” is set to 2. The Ranges are not effected by this setting, so the 150V range is still shown and used.

  • Page 24: Measurement Setup

    Measurement Setup Central to setting the proper range of the instrument is the Crest Factor. Crest factor is the ratio of the peak value of a waveform to the RMS value of the waveform. For example, a perfect sine wave crest factor RMS value is 0.707*Peak. The crest factor is the inverse of the normalized RMS value, 0.707 = 1.414.

    Measurement Setup Note: Measurement accuracy is improved by minimizing the range for a given input signal. 3.4 Auto Voltage and Current range The measurement range adjusts automatically according to the input signal, and uses same ranges as in Fixed range mode.

  • Page 31: Waveform Display Function

    Waveform Display Function The 5335C power meter displays waveform representations of the sampled data measured. This function is designed to be similar to an oscilloscope with many of the typical functions of oscilloscopes available, like trigger, run/stop and single trigger. The capture of data is not limited to that displayed onscreen, the measurement interval is also involved. For example, measuring a 15Hz signal with the interval set to 0.1s does not allow for stable measurement of the frequency.
