TPI DIGITAL CLAMP-ON METER TERMINOLOGY
>> Agency Approval: Test equipment with the CE or UL mark have
passed through tests and are designed with operators safety in mind.
>> Auto Range: Meter automatically selects the appropriate range after
the function has been selected.
>> Trim Mode: A feature that stabilizes the display when measuring
unstable or fast moving signals.
>> Basic DC Accuracy: Important specification affecting the overall
accuracy of all functions on a DMM.
>> Resolution: A measurement of how small of a signal a meter can
display. This specification must be taken into account with accuracy to
determine the overall capability of a DMM.
>> True RMS: Allows accurate measurement of non-sinusoidal AC volt-
age and current found in many control and switching power supply
circuits.
>> Analog Bar Graph: Provides the ability to see rapidly changing
signals too fast for the digital display to see.
>> Min/ Max/ Peak: Record and display the minimum and maximum
readings measured. Also dispplay the peak voltage or current reading.
This feature is useful when looking for trends over a long period of
time or when measuring in rush current.

erminology
>> Sleep/Auto Off: Automatically powers instrument down after 30
minutes of inactivity to preserve battery life. Meters with sleep mode
will still acquire data during this time
>> Data Hold: Freezes the reading on the display. This feature is useful
when recording readings on paper or when in hard to see locations.
Triple display meters can hold two readings on the display at the same
time.
>> Peak Hold: Measure and freeze on the display the maximum voltage
or current reading. This feature is useful when measuring in rush
current.
>> Relative Mode: Displays measured value as a percentage of the
stored value. This feature is useful for component checking.
>> Audible Continuity: Audible beep indicating a complete circuit
connnection
>> Non-Contact Voltage Detection: Meters with this capability have a
sensor that detects the presense of voltage when the meter is held next
to a voltage source.
>> % Harmonic Distortion: Indicates if the signal under test is clean or
distorted
>> Category I: Usually electronic equipment or
equipment where measures have been taken to limit
transient over voltages.
>> Category II: Single phase loads like appliance
personal computers, television sets, and other
household loads. Outlets located more than 30 feet from a
CAT III source or more than 60 feet from a CAT IV source.
>> Category III: Distribution level fixed installations like
distribution panel devices, short branch and feeder
circuits, three phase loads, and single phase
commercial lighting.
>> Category IV: Equipment and lines located on the power
line side of a service panel or where a low voltage
connection is made to utility power
