HIOKI PW3360-21 Clamp On Power Logger

Extensive measurement capabilities in a compact package
Similar to its sister product, the PW3360-21 is 43% smaller by volume than the product it replaces ( Model 3169-20/ 21) , yet it is capable of recording power variations over extended periods of time despite this compact size. Used with a genuine Hioki SD card, it can record up to one year of measurements at one-minute intervals. The logger is designed primarily for use in applications involving the verification of energy-saving results.
The Clamp On Power Logger’ s compact size allows it to be installed in confined spaces inside electrical panels, and its broad operating temperature range of -10° C to 50° C, which exceeds that of previous devices ( 0° C to 40° C) , enables measurement in harsh environments. It can measure targets ranging from single-phase lines to three-phase/ four-wire, 400 V lines.
Graph display that provides an instant understanding of power utilization ( new feature)
With the launch of the PW3360-21, Hioki has added new functionality for displaying demand and trend graphs in both loggers. This feature makes it easy for operators to assess power use.
Demand refers to average power utilization over a specified interval, e.g., 30 minutes, and is used to determine the basic rate for electrical fees. Consequently, careful management of demand provides a means of lowering electrical fees. A demand graph can be used to check the maximum demand value and the time at which it occurred, aiding in demand management.
Users can also select one of the logger’ s measurement parameters* for which to display changes in the power trend as a graph using the PW3360-21’ s trend graph feature, allowing assessment of changes in power utilization based on the operating status of the equipment in question.

Quick Set navigation helps prevent measurement mistakes
To measure power at a high level of reliability, it is necessary to properly configure settings and correctly connect the instrument to the circuit being measured. Hioki’ s Quick Set navigation function provides instructions for configuring settings and wiring modes, checking connections, and starting recording, all in a series of easy-to-understand steps. In this way, the instrument eliminates erroneous settings and connections and offers robust support for reliable measurement. The ability to display color-coded three-phase connection and vector diagrams on its color display makes it easy to visualize the measurement circuit at a glance.
Leak current measurement and pulse input for expanded capabilities
Combined with an optional clamp leak sensor, the PW3360-21 can be used to measure leak current. If a clamp leak sensor is used in combination with a power measurement clamp sensor, the logger can make power measurements and test for current leaks at the same time. In energy-saving programs at manufacturing plants, power consumption per unit of production is managed based on production volume and power data. The PW3360-21 accepts pulse input for tracking production volume count information, allowing it to simultaneously record power and pulse count data.
The LR8431-20 uses a high-brightness QVGA TFT wide LCD, ensuring waveforms are easy to see.
Continuous operation, even in locations where AC power is unavailable
When measuring or logging power in a setting such as an electrical substation, AC power supply may not be readily available. By using the optional PW9002 Battery Set, the PW3360-21 can be driven on battery power for a full work day, or approximately eight hours. Additionally, the PW9003 Power Supply Adapter can be used to draw power from measurement lines, facilitating continuous power measurement.
