A.W. Sperry Instruments AWS DIGISNAP DSA-2002 User Manual

Sec.6.1 Safety Procedures
The following safety precautions must be observed to
insure maximum personal safety during the operation,
service and repair of this meter:
at
10.
Bae
Read these operating instructions thoroughly and
completely before operating your meter. Pay
particular attention to WARNINGS which will inform
you of potentially dangerous procedures. The
instructions in these warnings must be followed.
. Always inspect your meter, test leads and accessories
for any sign of damage or abnormality before every
use. If any abnormal conditions exist (eg. broken test
leads, cracked cases, display not reading, etc.), do not
attempt to take any measurements. Refer to Return
for Repair section.
. Never ground yourself when taking electrical
measurements. Do not touch exposed metal pipes,
outlets, fixtures, etc., which might be at ground
potential. Keep your body isolated from ground by
using dry clothing, rubber shoes, rubber mats or any
approved insulating material.
. To avoid electric shock use CAUTION when working
with voltages above 40Vdc or 20Vac. Such voltages
pose a shock hazard.
. Never exceed the maximum allowable input value of
any function when taking a measurement. Refer to the
chart on page 5 for maximum inputs.
. Never touch exposed wiring, connections or any live
circuit when attempting to take measurements.
. Do not attempt to operate this instument in an
explosive atmosphere (i.e. in the presence of
flammable gases or fumes, vapor or dust).
. When testing for the presence of voltage, make sure
the voltage function is operating properly by reading a
known voltage in that function before assuming that a
zero reading indicates a no-voltage condition.
. Calibration and repair should be performed by
qualified maintenance personnel.
Do not attempt calibration or service unless another
person, capable of rendering first aid and
resuscitation is present.
Do not install substitute parts or perform any
unauthorized modification of the instument. Return
the instrument to A.W. Sperry Instruments for service
and repair to insure that safety features are
maintained.

Sec.6.2 AC Current Measurements
WARNING
The DIGISNAP Series are designed to take current
measurements on circuits with a maximum voltage
difference of 500Vac/dc between any conductor
and ground potential. Using the DIGISNAP for
current measurements on circuits above this
voltage may cause electric shock, instrument
damage and/or damage to the equipment under
test.
Before measuring current, make certain that the
test leads are removed from the instrument.
. Set the Range Selector Switch to the 2000Aac range.
The letter A will appear on the display indicating the
current function.
CAUTION
The DIGISNAP is overload protected up to 3000A. Do
not take current readings on circuits where the
maximum current potential is not known. Do not
exceed the maximum current that this instrument is
designed to measure.
. Open transformer jaws by pressing against the trigger.
. Enclose one conductor in the transformer jaws and
release the trigger (see Fig. 3). The jaws should be
completely closed and the conductor centered in the
jaws before taking a reading.

indicated reading is below 200A, set the Range Selector
Switch to the 200A range.
