ELITEpro & DATApro (discontinued)

Common issues surrounding connectivity to Legacy ELITEpro meters is COM port selection. If the correct COM port is not selected, the software will be unable to contact the meter and will give the “Could not wake logger” response.

To resolve this, select Tools > PC Setup. A separate window will open where there is a Port drop down menu that you can use to select your COM port. Look for a port that references your RS-232 connection (either direct serial port or a USB-to-Serial adapter), select this port, and click “Save Changes.” Attempt to connect again.

If this does not work, ensure your cable is connected and that you have a null modem adapter between the serial connection and the meter (if you are not already using a null modem cable).

If the logger still does not connect, it may have a dead battery, damaged RS-232 pins, or simple internal damage to the meter itself that is preventing communication. More in-depth troubleshooting would be necessary to check for these possibilities, but the first and simplest test is the COM port setting. Contact technical support for additional assistance (

No, the DATApro is not compatible with ELOG 11/12. If you require replacement software for your DATApro, ELOG 2009 is compatible. Contact us for details.
These are the periods that the logger will post data for. You can use 3, 15, or 30 sec., 1, 2, 5, 10, 15, or 30 min., or 1, 12, or 24 hour interval periods with the ELITEpro. All recorded values will have a time stamp using one of the above periods.
There are two answers to this question: (1) for situations where your ELITEpro is running on battery power only and (2) in situations where your ELITEpro is using external (wall) or Line-Power. (1) A logger using battery power only will take a sample every 1 minute and then go to sleep. For example: If you are set for a 5 minute integration period, the logger will wake every 60 seconds and take a sample. After 5 minutes, the logger will average the 5 samples and record the requested data. (2) If the logger is using external power, it will take a sample every 3 seconds regardless of the specified recording interval. So for example, if you are set for a 5 minute integration period, the logger will take a sample every 3 seconds and then use all 100 samples taken to find the Average, Minimum, and Maximum readings.
When a sampling interval occurs, the ELITEpro measures 128 points along a single 360° cycle for each phase being measured. It then calculates RMS values for each point and records the product for each requested sample as determined by the setup table.
This is the process of digitizing an analog waveform. The logger has a sampling frequency of 7.68kHz (128 points per waveform). The ELITEpro uses two 12 bit A/D to sample both current and voltage waveforms simultaneously. The data points from the waveform sampling are used for all calculations.
Most likely it is because you are powering the instrument from the internal batteries. When running from the internal batteries the rate at which it will sample is once per minute. This preserves the batteries. When sampling on external power (9V transformer) the instrument senses the power and switches into a fast sampling mode (once every 3 seconds).
Every three seconds is the fastest sampling rate at which the ELITEpro can record data. In order to record at less than one minute intervals, the ELITEpro must be either plugged into a wall outlet, or, if the unit has the ‘Line-Power’ option, drawing out power through the voltage leads. One minute is the fastest sampling rate for an ELITEpro using battery power only.
The CT inputs of the ELITEpro can handle a maximum of 450mV or AC current. All of the CT’s provided by DENT Instruments are shunted to output 0-333mVAC at rated current.
The logger can use a external cell modem to provide data transfer from a remote location. Cell phone modems can be connected to the loggers serial port and provide a baud rate of 2400 baud. There is an option in PC Setup to set the software for extended timeouts for cellular communications. This feature will add timing delays and prevent dropouts. You can use AUTOPOLL, AUTOHOST or the manual dial features to retrieve logger data.
Battery life for the PRO series instruments is generally 3 years. The standard instrument uses one lithium C cell and the modem instrument uses two lithium C cells. The batteries are in holders and are easily replaceable. Contact the factory for availability and instructions. Note: Use the wall transformer whenever possible as this provides external power to the instrument and extends battery life.
The internal modem of the PRO series instruments is 14.4k baud.
The best way to calculate the memory is in the first page of a setup table. Create the set up table in ELOG and view the calculated memory from the first page of the set up table. You can alter the table easily and see how it affects total memory.
Yes! Simply set the logger to 50Hz on the first page of the Set Up Table. At 400Hz, the logger will sample at 16 times per cycle. This method works very well as long as there is little harmonic current beyond the 7th harmonic (2800Hx). 
The usual reason is that the two meters are not calculating VA and Power Factor in the same way. Some meters include harmonics in the calculation and some do not. The ELITEpro can do both depending on whether the 2 watt-element method is being used (does not include harmonics) or the 3 watt-element method (does include harmonics).
The ELITEpro is a poly-phase power meter designed to measure electrical loads up to 600V. The DATApro is a four channel logging device designed to measure data provided from outside sensors that can produce any of the following inputs; 4-20mA, 0-10VDC, electrical currents, temperature signals, or pulse signals.
Only our ELITEpro™ can monitor harmonics and waveforms and allow you to view it in real time however, the ELITEpro™ will not store this data. It will allow you to take a snapshot to attach to a file.
The standard memory is 128k (25,000 records) and the upgraded 512k memory (100,000 records) comes as an option. Memory capacity is a function of the integration interval, and recording flags set.
We are no longer offering upgrades to the legacy ELITEpro and DATApro instruments. Contact the factory for details.
3,15,30 seconds, 1, 2,5, 10, 15, 20, 30 minutes, and 1,12, 24 hours.
Three types: split-core, clamp-on and flexible (Rogowski). You may learn more about available CTs here.
Only if they are shunted to 333mV’s. This is the required input for both instruments. The CT inputs of the ELITEpro can handle a maximum of 450mV of AC current.
Recording continues using the internal battery, however the sampling rate will change from every 3 seconds to once per minute to help extend battery life. Data that has been captured will be lost if the instrument goes completely dead.
No, however you can delay start until a specific date and time.
The typical battery life with these instruments is 3 years when the integration (data collection) interval is 1 minute or longer. The battery life can be as short as 1 month if the integration interval is set to less than 1 minute. The battery is user replaceable. Contact the factory for availability and replacement instructions.
Sampling rate is the frequency measured in times per second that a logger reads each sensor. The ELITEpro™ reads once every three seconds (except when battery power is being used then it is once every minute). The integration interval is the period of time over which the samples that are read during the sampling rate, are averaged and then stored into the loggers memory.
This is the number of points on a given waveform that are measured and the values used to calculate RMS volts, and watts. The ELITEpro™ samples at 128 points per cycle regardless of how often a channel is read.
