Dranetz True RMS Precision Digital Multimeter Kit, PowerLogger® 10 - 600V

Features & Applications:

This Dranetz True RMS precision digital 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. 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.

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. 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.

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. 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. 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). 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.
