WARNING
SAFETY INFORMATION
WARNING
The meter has been designed according to IEC-61010 concerning
electronic measuring instruments with a measurement category
III ( CAT III 300V ) and pollution degree 2.
To avoid possible electric shock or personal injury, follow these
guidelines:
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, vapour, or dust.
Do not apply a voltage or current higher than the selected
range's upper limit between terminals.
Before use, verify the meter's operation by measuring a known
voltage.
connecting the meter to 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 with voltage above 30 V AC RMS,
42 V peak, or 60 V DC. Such voltages pose a shock hazard.

WARNING
When using the probes, keep your fingers behind the finger
guards on the probes.
Connect the black test lead before you connect the red test
lead. When you disconnect test leads, disconnect the red 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 electric shock, do not touch any naked conductor
with hand or skin, and do not ground yourself while using the meter.
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!

INSTRUCTION
There are five scales:
The upper scale is for resistance measurements.
The second scale " " is for the measurements of DC voltage,
AC voltage ( except AC 12 V range ), and DC current.
The third scale is only for AC voltage measurements of the AC
12 V range.
The fourth scale "dB" is for decibels.
The fifth scale "BATT" is for battery test.

OPERATING INSTRUCTIONS
Points to be Observed before Operation
Before measuring, check the pointer to see whether it
exactly rests at the "0" position, and if not, adjust the
pointer with the zero set control ( Figure 3 ).
Insert the red test lead to the "+" jack and black test lead
to the "−" jack.
If the magnitude of the voltage or current to be measured is
not known beforehand, always set the selector switch to
the highest range, and then work down to an appropriate
range in order to avoid damage to the meter.
Don't touch any conductor with hand or skin to avoid
electric shock.

OPERATING INSTRUCTIONS
DC Voltage Measurement
Set the selector switch to the desired " V " range.
Connect the test leads across the circuit to be measured.
Note: The black test lead must be connected to the
negative potential of the circuit; the red test lead must
be connected to the positive potential of the circuit.
If the pointer deflects to the left of the scale, reverse
the test leads.

If the selector switch is in 12 V range position, reading is
taken from the third scale " AC 12 V".
If the selector switch is in 60 V, 120 V, or 300 V range
position, reading is taken from the second scale " ".

OPERATING INSTRUCTIONS
Resistance Measurement
Set the selector switch to the desired " " range.
Short the red and black test leads and turn the 0 adjuster
knob until the pointer rests in "0" position of the upper scale.
Note: If the pointer can't be adjusted to the "0" position,
replace the battery ( AA, 1.5 V battery ).
Connect the test leads across the load to be measured.
Reading is taken from the upper scale. To get a correct
resistance value, multiply the reading by the number
specified in the range selected. For example:
If you use "X10" range, you should multiply the reading by
10. The result is the resistance value of the tested load.
F. Decibel Measurement
Decibel is measured in the same way as AC V measurement
reading the dB scale instead.
For measurements in the AC 12 V range, the dB scale (-20 to
+22) is read directly. If the reading is higher than +22dB, use the
60 V, 120 V or 300 V range, and add a fixed sum of dB to the
respective reading as follows:
For AC 60 V range, add 14 dB to the reading.
For AC 120 V range, add 20 dB to the reading.
For AC 300 V range, add 28 dB to the reading.
Note: When measuring a signal which contains a direct current,
a 0.1 μF blocking capacitor with the voltage endurance of
more than 300 V should be connected in series.
