| PowerLogger 10 - Precision Digital Multimeter, Power Meter PowerLogger10 multimeter is a power quality troubleshooting tool, as well as a high performance precision instrument for laboratory use, service and training. With a display range of 300,000 counts, as well as outstanding accuracy and long-term stability, it fulfills all requirements for use in calibration and R&D laboratories. The instrument can be utilized on-site for precision maintenance and calibration tasks thanks to battery operation. Features The momentary measured value and up to two additional values are displayed simultaneously, for example: - Momentary, minimum and maximum measured values
- Frequency and RMS value of AC measuring voltage
- Momentary measured values as well as active power, voltage and current
- Maximum value for periodic power with date and time
High Resolution and Precision 5¾ places ( 309,999 counts) for DC measured quantities and 4¾ places ( 30,999 counts) for AC measured quantities allow for precision reference measurements and use as a calibration standard for testing devices and assemblies. RMS Value with Distorted Waveshape The utilized measuring method allows for waveshape independent RMS measurement (TRMS AC and AC+DC) up to 100 kHz, and up to a crest factor of 5. Additional Functions Continuity testing with acoustic signal, events counting (number and duration), counting of zero-crossings, stopwatch, data-compare and extended-range capacitance measurement. Type J and K thermocouples and platinum sensors can be connected thanks to the integrated temperature measuring function. Overload Protection The instrument is safeguarded for up to 600 V in all measuring functions by overload protection. An acoustic signal is generated if the upper voltage or current range limit is exceeded. FUSE appears at the display if the fuse for the current measuring ranges blows. Calibration Certificate The multimeters are furnished with an internationally valid DKD calibration certificate. After the specified calibration interval has elapsed (recommended interval: 1 year), the multimeters can be recalibrated in our own, or any other accredited DKD calibration laboratory. Infrared Data Interface The device can be remote configured, and momentary and saved measurement data can be read out via the bidirectional infrared interface supplied as standard equipment. The RS232 or USB interface adapter as well as DranWin 10 software, are required to this end (see accessories). Device driver software for LabView is available upon request. Automatic Blocking Sockets (ABS) * Automatic blocking sockets prevent incorrect connection of measurement cables and inadvertent selection of the wrong measured quantity. This significantly reduces danger to the user, the instrument and the system under test, and in many cases eliminates it entirely. Automatic Measured Value Storage with Comparison * The DATA function automatically saves the digitally displayed measured value after settling in. Acoustic signaling is also used to indicate whether the new measured value deviates from the initial reference value less or more than 33% of the measuring range. Power Saving Circuit The device is switched off automatically if the measured value remains unchanged for a period of approximately 10 minutes, and if none of the controls are activated during this time. Automatic shutdown can be deactivated. Connector Jack for External Power Supply Our NA5/600 can be connected for long term measurement, especially in memory mode operation, and for power disturbance recording. As opposed to common plug-in power packs, the NA5/600 includes a regulated output with minimal residual ripple and coupling capacitance to the mains input, as well as a highly insulated power cable. Measurement accuracy influences are thus minimized, and there is no impairment of electrical safety. * Patented Additional Functions for PowerLogger 10 Power Measurement The PowerLogger 10 is a compact power meter for direct and alternating current in single-phase systems. The electrical circuit can be connected either directly, or via a current transformer. If a current transformer is connected to the multimeter (mA or A input), all current and power displays are represented with the correct value based upon the selected transformation ratio of 1000:1 or 10,000:1. Universal power measurement includes the following measuring functions: active, reactive and apparent power, power factor and energy. Beyond this, the mean power value can be generated over a specified time period (e.g. 15 min.), and the corresponding maximum value can be recorded along with time of occurrence. Power Disturbance Recording The PowerLogger 10 is equipped with a function for acquiring and recording power disturbances which is unique amongst the handheld multimeters. This allows for simultaneous, continuous recording of voltage characteristics and event-triggered recording of voltage dips (> 10 ms) and voltage transients (> 0.5 ms). One of two different recording and analysis modes can be selected: - If a power disturbance occurs, its type, time of occurrence, duration and maximum value are entered to an events list (capacity: 250 events, volatile memory), whose contents can be viewed at the multimeter display.
- Same as above plus additional recording of measured values to internal measured value memory when events occur (capacity: approx. 60,000 measured values). Memory contents can be read out with DranWin 10 software and analyzed in detail.
Memory Mode Operation The PowerLogger 10 is equipped with a quartz-movement synchronized measurement data memory (128 kB), which has enough capacity for 13,000 to 120,000 measured values depending upon configuration. This allows for utilization of the instrument as an autonomous real-time data logger. Measurement data recording is executed either: - In a time controlled fashion with an adjustable sampling interval within a range of 0.5 ms (for V DC only) to 10 minutes (see sampling rate in the table on page 3)
- Dependent upon measured value in the event of exceeded limit/delta value
- As an individual measured value by pressing a key
Memory contents can be read out by a PC with the help of the RS232 or the USB adapter, and can be analyzed and documented with DranWin 10 analysis software. |
