POWER MEASUREMENTS
For the measurement of power, the Power Adaptor (included) is required. This adaptor
consists of a three-prong plug and three-prong socket on one end (for connection to
loads under test) and a multi-plug on the other end (for insertion into meter's input
terminals).
WARNING
The power adaptor included with this item is designed to be used
with the Extech Model 382860 Power Multimeter.
DO NOT USE IT WITH ANY OTHER MULTIMETER
Test Procedure
1. The Power Adaptor must be connected to the meter before Power
measurements can be made. Once connected, set the Rotary Switch to the
Power position.
2. Connect the multi-plug side of the adaptor to the meter's input terminals. The
multi-plug is labeled with '20A' on the left, 'COM' in the middle, and 'V/ohms'
on the right. Always connect the correct contacts for all plug connections. The
labeling on the Power Adaptor matches the meter's labeled input terminals for
convenience.
3. Connect the appliance/load under test (not powered) to the socket of the
Power Adaptor.
4. Power the load under test by inserting the three-prong plug into a 117VAC
outlet. Readings can now be observed on the LCDS.
5. The maximum AC current that the meter can accept is 13A for short periods of
time (30 seconds or less). Never exceed this limit. 12A can be safely
monitored continuously.
WARNING: If the connection between adaptor and meter is incorrect, severe meter
damage will result. In addition, a risk of electric shock exists. Finally, DO NOT select
any other range other than POWER while the adaptor is connected to the meter.
Serious meter damage and injury can occur.
