FCC INFORMATION

NOTE: This equipment has been tested and found to comply with the limits for

a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

To ensure safe operation and service of the tester, follow these instructions.
Failure to observe these warnings can result in severe injury or death.

• Before each use, verify meter operation by measuring a known voltage
or current.

• Never use the meter on a circuit with voltages that exceed the category
based rating of this meter.

• Do not use the meter during electrical storms, or in wet weather.

• Do not use the meter or test leads if they appear to be damaged.

• Ensure meter leads are fully seated, and keep fingers away from the
metal probe contacts when making measurements.

• Do not open the meter to replace batteries while the probes are
connected.

• Use caution when working with voltages above 60V DC, or 25V AC RMS.
Such voltages pose a shock hazard.

WARNINGS

• To avoid false readings that can lead to electrical shock, replace

CAUTION : Changes or modifications not expressly approved by the

manufacturer responsible for compliance could void the user’s authority to
operate the equipment.

batteries if a low battery indicator appears.

• Unless measuring voltage or current, shut off and lock out power before
measuring resistance or capacitance.

• Always adhere to local and national safety codes. Use Personal

BATTERY REPLACEMENT

Protective Equipment (PPE) to prevent shock and arc blast injury.

• When indicator is displayed on the LCD, batteries must be replaced.

• Remove the back screw and replace 6 x AAA batteries.

Turn instrument off and disconnect test leads. Clean the instrument by using
a damp cloth. Do not use abrasive cleaners or solvents.

Remove the batteries when instrument is not in use for a prolonged period
of time. Do not expose to high temperatures or humidity. After a period
of storage in extreme conditions exceeding the limits mentioned in the
Specifications section, allow the instrument to return to normal operating
conditions before using it.

• Non-Contact Voltage Detection key is used to detect power
with a sensor located at the tip of the clamp head and indicates
positive response with an audible alarm and visual LED indicator
light just above the “NCV” button.

• Do not use non-contact voltage detector to determine if there
is current in the wire. Detection operation could be affected by
socket design, insulation thickness, type and other factors.

• Voltage indicator light may also light when voltage is present on
the meter’s input jack or from external interference sources such
as motors, flashlights etc.

• Press to enter Max / Min mode; the largest and smallest values
will be saved while in this mode.

• Press repeatedly to alternate between the maximum and
minimum readings.

• Press for 2 seconds to return to live reading and clear the stored
maximum and minimum values.

Note: Select range prior to selecting Min/Max to capture large
values

The UEi LRA Inrush is programmed to properly capture the starting
current for compressor motors.

• Select AC Amps

• Select the range capable of capturing the maximum value

• Press and hold LRA Inrush for two seconds – INRUSH will now
be shown on the screen

• Activate compressor and read value on the display

• Press and hold LRA Inrush for two seconds to exit

• Press repeatedly to cycle through manual ranges.

• Press for 2 seconds to return to auto ranging mode.

• AT is displayed on LCD only during auto ranging mode.

Note: Select range prior to Min/Max for best results.
