Instruction Manual
DIGITAL CLAMP MULTIMETER

Overall, Safety Standards, Safety Symbols, Notices Overall
This digital AC clamp meter is a stable and reliable instrument with micro smart IC and dual integral AD transformer as the core, coming with full range overload protection circuit. It can be used to test AC, AC voltage, resistor, diode, circuit continuity.
Safety Standards This instrument has been designed and manufactured
with safety standards of IEC61010 , IEC61010-2-032, dual insulation CAT III 600V and pollution class 2.
Safety Symbols Warning symbols, cautiously operate. High voltage danger symbol. Allow to be used nearby by conductors which are not dangerous with life. Dual insulation (Class II safety equipment) Ground.
Notice Read the manual carefully , especially notice the
contents with symbols. Please follow the instructions. If the test pen needs to be replaced, replace a new
one with the same model number or same specifications

Accessories Check the instrument and test pen before use. If exposure of test leads, broken cover, abnormal display are found, do not use it. In test, do not touch the terminal not in use. When test DC voltage higher than 60V or AC voltage higher than 30V, do not reach your fingers beyond safety barrier. When the measured range is unknown, put the test range at the maximum. Do not test voltage higher than maximum range. The test lead should be away from tested circuit before switch range selector. Before test diode in live circuit, cut off the power and discharge all capacitors. Do not expose the instrument in strong light, high temperature or damp environments. Do not touch naked circuit lines, connectors or measured circuits.

Instructions Instructions AC and DV Voltage Measurement Insert the read test lead into the ” ” jack and black test lead into the “COM” jack. A.DV Voltage Measurement Turn the rotatory range selector to , connect the test lead to voltage to be measured. Read measurement value and polarity of red test lead from display. B. AV Voltage Measurement Turn the rotatory range selector to , connect the test lead to voltage to be measured. Read measurement value from display.
Caution: *If the measured voltage range is not known in advance, turn the rotatory range selector to maximum. Then decrease gradually to get satisfactory resolution. *Beware of electric safety in measuring high voltage.
AC current measurement 1.Turn the rotatory range selector to AC current ; 2.Clamp the jaw around the conductor to be measured. Do not more than one conductors at the same time. 3.Read measurement value from display. Notice *If the measured current range is not known in advance,

Instructions turn the rotatory range selector to maximum. Then decrease gradually to get satisfactory resolution.
Resistor Measurement 1.Insert the read test lead into the ” ” jack and black test lead into the “COM” jack. 2.Turn the rotatory range selector to” “, press “SEL” button to switch to , place the test probe tips into contact with the sample to be measured. 3.Read measurement value from display. Notice: *If the measured sample has higher resistance beyond maximum range, “OL” will be display. Please change to use a meter with higher measurement range. *When measuring a resistance, make sure power is off and all capacitors are fully discharged. *When measuring resistance over 1M OHM, it might take a few seconds to stabilize the reading.
Diode and Continuity Test Insert the read test lead into the ” ” jack and black test lead into the “COM” jack. Polarity of red test lead is “+”.

Instructions, Auto Off
1. Turn the rotatory range selector to” “, press “SEL” button to switch to . Bring the red test lead in contact with positive electrode and black test lead in contact with negative electrode. Read forward voltage drop value from the display. 2. Turn the rotatory range selector to” “, press “SEL” button to switch to . Place the test leads in contact with two points of measured circuit. If the resistance is less than 50 OHM, the beeper emits continuous sound.
Auto Off The unit powers off automatically when stay idle over 25 minutes to save power.
