The single-phase comes equipped with a TaskCard that allows it to operate in four modes, including Scope Mode, for real-time viewing of waveforms; Meter Mode, for second-by-second measurement of up to 16 parameters; Event Recorder, to view recorded event data for immediate problem solving and troubleshooting; and Time Plots, to graph and display measurements. Company Profile Email Us. Combining ease of use and light weight less than 4 poundsthe hand-held is an 8-channel, 4-voltage and 4-current tool that can be operated in either battery or AC mode to measure, analyze and record power quality, harmonics and energy data simultaneously on 3-phase systems. When they need to know is how their power system is doing; the answers are there.

Wait sufficient time when Stopping monitoring to allow unit to process all data. Observe the unit after starting a survey for several journal intervals and make sure the compact flash card is not filling up too quickly.

This is an indication of a possible threshold set too tight. These values are optimized for clean utility power. You can turn these off or increase the limits. Turn off the unit while monitoring is ON Never delete files, rename files or format the compact flash card in the PC. Copying hostcode. Leave hostcode.

Only Scope mode. There is only one Frequency reading for each unit. It is not measured per channel You can enter Nominal values in the Nominal Values setup screen if you need to set up the unit without measurement connections If you find your data card will read data files in the unit but Windows will not recognize the card at all, you probably have a corrupt card. Many successful file recoveries have been done using shareware File Recovery programs.

Please have your serial number ready to give to our Customer Support person. Can I use any Compact Flash cards in my unit? Our application requires an extraordinary card that may not be available at the local computer store. A certain brand and model number that happens to work today may not work when bought at a future date. Dranetz qualifies the cards before they are shipped. We check and verify every card delivered from every supplier to make sure it meets the needs of the instrument.

Product performance may be compromised and Technical Support is not available for unauthorized cards. Why did my memory card fill up so fast?

It could be one of two reasons: 1. You have collected data at a high rate indicating a Power Quality problem and the data you have stored should be sufficient to analyze for a solution.

Your thresholds are set too tight for this particular survey. More than likely the Transient Limit section is the cause of this. The threshold defaults for Power Quality Mode are set up for typical Utility power, generally clean and stable. If you are monitoring a UPS input or output or other rectifier loads there is a good chance your voltage waveform has notching. This notching can and will cause multiple events every cycle.

Power Quality monitors are not designed to measure events every cycle when this waveform distortion is steady state.

Transient, by definition, is undesirable and momentary in nature. You should exercise caution when increasing thresholds, you do not want to set them too loose and lose valuable data.

You may see some increment but you should see long blocks of time in between. Not incrementing should be the norm. Another area to look at is your Journal Limits. Please check the website often to see if there are firmware and PC software upgrades. As a final check, before you select Start Now, view your setups and make sure the settings are what you expect.

You can find this file in your Windows directory. PES always displays 3 years before the mid-year, and 2 years after. Save the PES. Restart PES.
