PEN TYPE DIGITAL MULTIMETER
OPERATOR’S MANUAL
1. Overview
The pen type digital multimeter is characterized at slim size,
portable, stable performance and anti-dropping capacity. Using
6000 counts digit LCD monitor with character 12mm high, they
offer clear readings. With overall circuitry design centering on
large-scale IC A/D converters in conjunction and over-load
protection circuit, the meters give excellent performance and
exquisite making as a handy utility instrument.
The meters can be used to measure DC & AC voltage, resistance,
capacitor, positive diode voltage fall and audible continuity. If the
equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.

7. OPERATING INSTRUCTIONS
7-1 Attention before operation
7-1-1 Check battery. When the battery voltage drop below proper
operation range, the “ ” symbol will appear on the LCD display
and the battery need to changed.
7-1-2 Pay attention to the “ ” besides the input jack which shows
that the input voltage should be within the specified value.
7-1-3 The toggle switch should be positioned to desired range for
measurement before operation.
7-2 Measuring DC & AC Voltage
7-2-1 Set the toggle switch at the desired “V ” range position, it
shows symbol for testing DC voltage, if you want to test AC voltage,
push “SELECT” button switch.
7-2-2 Connect test leads across the source or load under
measurement.
7-2-3 You can get reading from LCD. The polarity of the red lead
connection will be indicated along with the DC voltage value.
NOTE:
1.“ ” means you can’t input the voltage more than 600V, it’s
possible to show higher voltage, but it may destroy the inner circuit
or pose a shock.
2. Be cautious against shock when measuring high Voltage.
7-3 Measuring Resistance
7-3-1 Set the toggle switch at the desired “ ” range
position.
7-3-2 Connect test leads across the resistance under
measurement.
7-3-3 You can get reading from LCD.
NOTE: Max. input overload: 600V rms＜10sec
1. For measuring resistance above 1MΩ, the mete may take a few
seconds to get stable reading.
2. When the input is not connected, i.e. at open circuit, the figure
‘OL’ will be displayed for the over-range condition.
3. When checking in-circuit resistance, be sure the circuit under
test has all power removed and that all capacitors have been
discharged fully.
7-4 Measuring Capacitance
7-4-1 Set the toggle switch at the desired “ ” range
position, push “SELECT” to choose Capacitance measurement.
7-4-2 Connect test leads across the capacitance under
measurement.
7-4-3 You can get reading from LCD.
NOTE: Max. input overload: 600V rms＜10sec
1. Capacitors should be discharged before being tested.
2. When testing large capacitance, it will take longer time before
the final indication ( For 100uF~60mF range, it will take about
10 seconds ).
3. When testing small capacitance (≤1uF), to assure the
measurement accuracy, first press "REL", then go on
measuring.
7-5 Diode & Audible continuity Testing
7-5-1 Set the toggle switch at the “ ” range position, push
“SELECT” to choose Diode or Audible continuity
measurement.
7-5-2 On diode range, connect the test leads across the diode
under measurement, display shows the approx. forward
voltage of this diode.
7-5-3 On Audible continuity range, connect the test leads to two
point of circuit, if the resistance is lower than approx. 50Ω, the
buzzer sounds.
NOTE: Make sure the power is cut off and all capacitors need to
be discharged under this measurement.
8. Battery replacement
8-1 When the battery voltage drop below proper operation range
the " " symbol will appear on the LCD display and the battery
need to changed.
8-2 Before changing the battery, set the toggle switch to “OFF”
position. Open the battery cover by rotary the battery cover.
8-3 Replace the old battery with the same type battery (AAA R03P
1.5V×2).
8-4 Close the battery cover and rotary the battery cover to lock it.
9. Maintenance
9-1 Use only moist fabric or small amount of detergent but not
chemical solution for cleaning.
9-2 Do not use the meter before the back cover is properly closed
and screw secured. Upon any abnormality, stop operation
immediately and send the meter for maintenance.
9-3 Please take out the battery when not using for a long time.
Above picture and content just for your reference. Please be
subject to the actual products if anything different or updated.
Please pardon for not informing in advance.
