This meter has been designed according to IEC-61010
concerning electronic measuring instruments with a mea-
surement category (CAT II 600 V) and pollution degree 2.
To avoid possible electric shock or personal injury, follow
these guidelines:
Warning
Do not use the meter if it is damaged. Before you use
the meter, inspect the case. Pay particular attention
to the insulation surrounding the connectors.
Inspect the test leads for damaged insulation or exposed
metal. Check the test leads for continuity. Replace
damaged test leads before you use the meter.
Do not use the meter if it operates abnormally.
Protection may be impaired. When in doubt, have the
meter serviced.
Do not operate the meter around explosive gas, vapor,
or dust.

connecting the meter in the circuit. Remember to place
the meter in series with the circuit.
When servicing the meter, use only specified
replacement parts.
Use caution when working above 30Vac rms, 42V peak,
or 60Vdc. Such voltages pose a shock hazard.
When using the probes, keep your fingers behind the
finger guards on the probes.
When making connections, connect the common test
lead before you connect the live test lead. When you
disconnect test leads, disconnect the live test lead first.
Remove the test leads from the meter before you open
the battery cover or the case.
Do not operate the meter with the battery cover or
portions of the case removed or loosened.
To avoid false readings, which could lead to possible
electric shock or personal injury, replace the battery as
soon as the low battery indicator ( " " ) appears.
When in Relative Mode, the symbol " " is displayed.
Caution must be used because hazardous voltage
may be present.
When in MIN mode, the symbol "MIN"is displayed.
Caution must be used because hazardous voltage
may be present.

s.
Do not use the meter in a manner not specified by this
manual or the safety features of the meter may be
impaired.
Remaining endangerment:
When an input terminal is connected to dangerous live
potential it is to be noted that this potential at all other
terminals can occur!
CATII - Measurement Category II is for measurements
performed on circuits directly connected to low voltage
installation.(Examples are measurements on household
appliances, portable tools and similar equipments .)
Do not use the meter for measurements within
Measurement Categories III and IV.

e.
Disconnect circuit power and discharge all capacitors
before testing resistance, diode, capacitor, temperature
and continuity.
Use the proper terminals, function, and range for your
measurements.
Before measuring current, check the meter's fuses and
turn off the power to the circuit before connecting the
meter to the circuit.
Before rotating the range switch to change functions,
disconnect test leads from the circuit under test.
Remove test leads from the meter before opening
the meter case or the battery cover.
Because of anti-interference designs, the meter may
stop working in strong interference environment. Turning
on the meter again can solve this problem.

18. Bar graph
http://www.all-sun.com

Using the Bar Graph
The bar graph at the bottom part of the LCD is a analog
display only for the measurements of ac/dc voltage, ac/dc
current and resistance. The length of its lit segments is
proportional to the present reading on the LCD. The bar
graph is unavailable for the other measurements. The bar
graph is like the needle on an analog meter. It has an
overload indicator ("") on its right and a negative polarity
indicator ("") on its left.
Because the bar graph updates about 30 times per second,
which is 10 times faster than the digital display, the bar
graph is useful for making peak and null adjustments and
for observing rapidly changing inputs.
The number of lit segments indicates the measured value
and is relative to the full-scale value of the selected range.
In the 600V range, for example, the major divisions on the
scale represent 0, 100, 200, 300, 400, 500 and 600V. An
input of - 100V lights the negative sign and the segments
up to the "10"on the scale.
