CLEANING
Clean the instrument by using a damp cloth. Do not use abrasive cleaners
or solvents.
Take care to keep the sensor lens clean at all times. Clean the lens using a soft
cloth or cotton swab with water or rubbing alcohol only, and allow the lens to
dry before use.
STORAGE
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.
DISPOSAL / RECYCLE
Do not place equipment and its accessories in the trash. Items
must be properly disposed of in accordance with local regulations.

I. Max/Min Hold
Press to enter Max/Min mode; the largest and smallest values will be
saved while in this mode.
Press repeatedly to alternative between the maximum and minimum
readings.
Press for 2 seconds to return to live reading and clear the stored
maximum and minimum values.
J. Hold/Auto Hold/Backlight
•
Hold captures the current displayed value.
Auto Hold captures the first stable displayed value, until a new stable
value is measured. The meter will then capture the new value and emit
a beep (V, Ohm, Temperature and Amp functions).
Press to hold current input on the display.
•
Press again to enter Auto-Hold to capture stable values.
Press again to return to normal operation.
•
Press and hold to activate display backlight.
Using lights drains the battery significantly.
K. L. Battery/Fuse Replacement
When
indicator is displayed on the LCD, batteries must be replaced.
•
Remove rubber boot, back screw and replace 2 x AAA batteries.
This meter uses 440mA/1000V (69192) and 11A/1000V (69191)
fast blow fuses.
M. Magnetic Hanger Accessory
(Optional, sold separately)
•
Slide magnetic adapter into protective rubber boot.
Attach instruments to metal for hands-free use.
N. Bar Graph
The bar graph shows an approximate analog representation
of a measurement.
•
The bar graph responds much faster than the digital display.
The scale of the bar graph is zero to the maximum reading of
the selected range.

WARNINGS
To ensure safe operation and service of the tester, follow these instructions.
Failure to observe theses 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 or fuses while the probes
are connected.
•
Use caution when working with voltages above 60V DC, or 25V AC
RMS. Such voltages pose a shock hazard.
•
To avoid false readings that can lead to electrical shock, replace
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 individual
protective equipment to prevent shock and arc blast injury where
hazardous live conductors are exposed.
