Section I – Introduction
Line Voltage Selection:
The AVM-2000 is delivered with an AC Power Module for operation from 120 ±10% VAC, 60 Hz. If
the AVM-2000 is to be operated from a 240 ±10% VAC, 50-400 Hz power source, or the input
power range needs to be changed from a previous selection, an alternative AC Power Module is
required. Contact TEGAM for a selection of input Power Modules.
CAUTION: DO NOT APPLY POWER TO THE INSTRUMENT BEFORE READING THIS SECTION.
Check the Power Cord
Make sure the power cord supplied with the Model AVM-2000 is not frayed, broken, or cracked. A
damaged power cord is a fire and electrical hazard. If the power cord is damaged, it should be
replaced.
Use the Proper Fuse
To avoid fire hazard, use only the correct fuse type as specified for the AC power supply in the unit.
The correct fuse for the AVM-2000 is a 1 1/4A, 3AG Slow Blow Fuse.
The fuse is located just below the power cord socket. Before replacing the fuse, place the Model
AVM-2000 front panel power switch to the OFF position and remove power cord on the back of the
Model AVM-2000. To replace the fuse, gently slide out the fuse drawer. Remove the old fuse and
snap a new one into the fuse holder. Reinstall the fuse by simply pushing the fuse drawer back into
its original position. The fuse drawer should snap into place.
Grounding the Equipment
ISOLATED OUTPUT
Two (Red and Black) binding posts with banana sockets (4mm) are provided to connect the AVM-
2000’s ISOLATED OUTPUT to an external device. A third (Yellow) binding post connected to the
AVM-2000 case which may be connected to earth ground via other connections to the instrument.
The ISOLATED OUTPUT red and black binding posts are electrically isolated from the HI and LO
input terminals. The signal level present at the ISOLATED OUTPUT is adjustable, via the OUTPUT
LEVEL control, from ± 0.5 V to ±1.5 V full scale for the RANGE selected. The ISOLATED OUTPUT
zero reference is adjusted during the Setup mode using the OUTPUT LEVEL control.
WARNING: To avoid electrical shock or other potential safety hazards, plug the power cord into a
properly wired receptacle before using this instrument. The proper grounding of this instrument is
essential for safety and optimizing instrument operation.
WARNING: Applying more than 1100 Volts across the input terminals or from either input terminal
to common or ground results in instrument damage not covered by the warranty.
NOTE: Rapid changes in input voltage potentially can result in voltages well in excess of 1100 Volts
due to reactive effects in the supply circuit—such induced voltage may damage the instrument
.
