Introduction
This product is a battery-powered, true-rms, autoranging digital multimeter with a 6000 counts
LCD display and a backlight.
Safety Information
To avoid possible electrical shock, fire, or
personal injury, please read all safety information
before you use the product. Please use the
product only as specified, or the protection
supplied by the product can be compromised.
• Examine the case before you use the product.
Look for cracks or missing plastic. Carefully look
at the insulation around the terminals.
• The measurement must be made with correct
input terminals and functions and within the
allowable measuring range.
1
• Do not use the product around explosive gas,
vapor, or in damp or wet environments.
• Keep fingers behind the finger guards on the
probes.
• When the product has already been connected
to the line being measured, do NOT touch the
input terminal that is not in service.
• Disconnect the test leads from the circuit before
changing the mode.
• When the voltage to be measured exceeds 36V
DC or 25V AC, the operator shall be careful
enough to avoid electric shock.
• Misuse of mode or range can lead to hazards,
be cautious. “ ” will be shown on the display
when the input is out of range.
• Low level of a battery will result in incorrect
readings. Change the batteries when battery
level is low. Do not make measurements when
the battery door is not properly placed.

mode. In manual range mode,
each
push
increases the range; when the
highest
range
is reached, the next push will lead
to
the
lowest range. To exit the manual
range
mode,
Long push forexit.

Push
this button to enter the relative
mode.
The
product will store the present
reading
as
a reference for subsequent
readings.
The
display is zeroed, and the
stored
reading
is subtracted from all
subsequent
readings
. Push again to exit the
relative
mode
.
Push
