OPERATING MANUAL
This kind of mini digital multimeter with test leads attached to its
cover will give you years of satisfactory service. Before using your
new instrument, please read this Operating Manual completely and
familiarize yourself thoroughly with all functions and connections.
SAFETY RULES
The meter has been designed according to IEC-61010 concerning
electronic measuring instruments with a measurement category
(CAT 11 500V) and Pollution degree 2.
.&..
WARNING
To avoid possible electric shock or personal injury, follow these
guidelines:
a. Do not use the meter if it is damaged. Before you use the meter,
inspect the case.
b. 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.
c. Do not use the meter if it operates abnormally. Protection may
be impaired. When in doubt, have the meter serviced.
d. Do not operate the meter around explosive gas, vapor, or dust.
e. Do not measure more than the rated voltage which is marked on
the meter.
f. Before use, verify the meter's operation by measuring a known
voltage.
g. When measuring current, tum off circuit power before connecting
the meter in the circuit. Remember to place the meter in series
with the circuit.
h. When servicing the meter, use only specified replacment parts.
i. Use with caution when working above 30V ac rms, 42V peak, or
60V de. Such voltages pose a shock hazard.
j. When using the probes, keep your fingers behind the finger guards
on the probes.
k. Connect the common test lead before you connect the live test
lead. When you disconnect test leads, disconnect the live test
lead first.
1. Do not operate the meter with the back cover or portions of the
case removed or loosened.
m. To avoid false readings, which could lead to possible electric
shock or personal injury, replace the batteries as soon as the
low battery indicator ( ·� " ) appears.
n. This meter is designed to be indoor use.
o. 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 Ill and IV.
Caution
To avoid possible damage to the meter or to the equipment under
test, follow these guidelines:
• Disconnect circuit power and discharge all capacitors before
testing resistance, diode and continuity.
• Use the proper 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.

OPERATING INSTRUCTION
DC VOLTAGE MEASUREMENT
Set the function switch at
V
position.
Set the range switch at desired position. If the magnitude of voltage
is not known beforehand, set the switch at the highest range and
reduce until satisfactory reading is obtained.
Connect test leads to device or circuit to be measured. Voltage
value will appear on the display along with the voltage polarity.
When the range switch is in 500V position, a "HV" sign will appear
on the display to remind you of high voltage measuring.
Special attention should be paid.
