The new Hioki Model PW3360-20 clamp-on power logger is a highly compact, hand-held power line analyser suitable for single-phase and three-phase, three-wire and four-wire circuits with voltages to 780 volts. The Hioki Model PW3360-20 is ideal for service work in remote areas by virtue of its optional rechargeable battery pack. LAN connectivity provided by the http server function permits display on a PC of measured values and also set up of measurement conditions via free software available from Hioki. The instrument’s USB port allows direct connection to a PC, which then allows recognition of the internal memory and SD cards. A range of current clamps provides measurement to 5000 amps, and power measurement to 9 Megawatt. Leakage clamp transducers are available permitting simultaneous measurement of up to three, single-phase circuits. Measurement parameters include voltage, current, frequency, power, apparent power, reactive power and power factor, as well as integrated demand. Data storage is via SD memory card allowing retention of several months’ data. Operation of the Hioki Model PW3360-20 is particularly intuitive, the operator being guided through the set-up by means of sample-schematics indicating the correct way of connecting current clamps and voltage connection leads, and screen-displayed, life-like, illustrated connectors to be used. In addition the operator is guided by short text messages indicating the measurement sequence to be followed. ... read more
