Introduction Congratulations on your purchase of the Extech 382090/382091 1000A 3-Phase Power Analyzer Datalogger. Model 382090 is for use with 60Hz power systems. Model 382091 is for use with 50Hz power systems. This package includes four (4) clamp-on meters and four (4) alligator clip leads that connect to the analyzer/datalogger. - Page 3 Safety This Operation Manual provides information and warnings essential for operating the Model 382090/382091 in a safe manner. Before using this meter, be sure to carefully read the following safety information. DANGER During high voltage measurements, incorrect measurement procedures could result in injury or death, as well as damage to the meter.
- Page 4 Always set up the measurement first and then connect test leads to the circuit. • Make connections to the meter first, before connecting leads to a live circuit. • Connect the ground lead first, then the voltage leads and the current probe. Disconnect in reverse order. 382090 382091 V4.0 09/07...
