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. When the clamps and
test leads are connected to the circuit under test the user can view up to ten power
measurement displays. Also, up to 20,000 data sets can be automatically stored by the
analyzer/datalogger. Stored readings can later be transferred to a PC. Real-time logging
(readings recorded and transferred to PC at the same time) is also supported. Careful
use of these instruments will provide years of reliable service.
Features
DANGER
During high voltage measurements, incorrect measurement procedures could result in
injury or death, as well as damage to the meter. Please read this manual carefully and be
sure to understand its contents before using the meter.
SAFETY SYMBOLS
This symbol printed on the meter alerts the operator to consult
corresponding manual topics before using related meter functions
Dangerous voltages
CAUTION
• The meter is designed for indoor use and can be safely used at temperatures
o o
ranging from 32 to 122 F (0 to 50 C).
• Do not store or use the meter where it will be exposed to direct sunlight, high
temperature, high humidity, or condensation. If exposed to such conditions, the
meter may be damaged, the insulation may deteriorate, and/or the meter may
no longer meet the published specifications.
• The meter is not waterproof or dustproof
• Do not use the unit where it may be exposed to corrosive or explosive gases
Preparation Safety
WARNING
• To prevent electrical shock, do not allow the meter to become wet and do not
handle the meter with wet hands.
• When working with live circuits, take all suitable precautions against accidents,
including the use of electrical safety gear such as rubber gloves, rubber boots,
and safety helmets.
Connection Safety
WARNING
• To prevent electrical shock, turn the power off before connecting the test leads.
• In order to prevent electrical shock and short-circuits, shut off the power to the
line under test before connecting the line under test to the voltage input
terminals.
CAUTION
The measurement input and synchronizing input are not isolated from each other.
Connecting either one means that the other is exposed and live with a danger of
electrical shock present. To avoid electrical shock, connect both terminals.
WARNING
To avoid electrical shock and/or meter damage, use caution when connecting test
leads to live components. The jaws of alligator clips can create a short circuit
between closely spaced live parts. Avoid making connections to feeder conductors or
bus bars at elevated potentials.
• Follow all city, state, and local codes. Obey posted instructions.
• Never assume that a circuit is de-energized, check it first.
• 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.
Weight: Meter: approx. 25.8 oz (730g); Current probe: approx. 11.6oz (333g)
