WARNING 1. Checks of Body and Test Lead

WARNING 3. Warning for High Voltage Measurements

WARNING 4. Dangerous Voltage Measurement Procedure

WARNING 2. High Power Line Measurements is Prohibited

Before measurement, confirm the body of this instrument and handle insulators of the Test Lead have no cracks or any other damages. Dust, grease and moisture must be removed.

Do not hold multimeter in your hands. Keep safety distance from power source or circuit to be measured not to touch the dangerous voltage. Attach black and red alligator clips to test lead pins. Turn off the power of the circuit to be measured when connecting test leads. After measurement, before detaching alligator clips (test leads), turn the circuit power off and discharge the all capacitors.

●

For dangerous voltage measurement, strictly observe the warnings below.

3-1. WARNINGS

Correct knowledge of electric measurements is essential to avoid unexpected danger such as operator's injury or damage to the instrument. Read carefully and observe the following precautions for safety measurements.

3. SAFETY PRECAUTIONS

Even for Low Energy Circuits of electric/electronic appliances, such as heating elements, small motors, line cords and plugs, High Voltage Measurements are very dangerous. Do not touch any part of the circuit.

Do not measure High Power Line (High Energy Circuits) such as Distribution Transformers, Bus Bars and Large Motors. High Power Line sometimes includes High Surge Voltage that could cause explosive short in the instrument and could result in shock hazard. Generally, shock hazard could occur when the current between the circuit, that involves more than 33V rms or 46.7V DC or peak, and ground goes up to 0.5mA or more.

WARNING 1. Correct Selection of Function Switch

WARNING 2. Maximum Input Observance

WARNING 3. Test Lead Detachment

Do not measure anything that might exceed the specified maximum input values.

Always confirm that FUNCTION Switch is set to the correct position. Do not measure voltage except at Voltage measurement function.

Detach test leads from measuring circuit before changing measurement functions or removing rear cover for battery or fuse replacement.

In case of live-line measurement, strictly observe the warnings below

Do not hold multimeter in your hands. Keep safety distance from power source or circuit to be measured not to touch the dangerous voltage. Black test lead : Attach black alligator clip and connect to − (earth) side of the circuit. Red test lead : Connect to ＋ (positive) side of the circuit.

●

3-3. GENERAL WARNINGS AND CAUTIONS

Children and the persons who do not have enough knowledge about electric measurements must not use this instrument. Do not measure the electricity naked or barefooted to protect yourself from electrical shock hazard. Be careful not to get hurt with the sharp test lead pins. Do not polish the case or attempt to clean it with any cleaning fluid like gasoline or benzine. If necessary, use silicon oil or antistatic fluid. Away the instrument from hot and humid conditions like in the car. Do not apply hard mechanical shock or vibration. Remove the battery when the instrument is out of use for a long time. The exhausted battery might leak electrolyte and corrode the inside.

Press Level Key during IP RPM measurement. Input sensitivity level is changed as Level 3→2→1→4. (default setting is Level 3). Sensitivity level is shown with the number of " " under the bar graph. Change of input sensitivity is effective in the following cases. When measured value is unstable, reduce the current input sensitivity level. When measured value is "0", increase the current input sensitivity level.

Insert black test lead to COM terminal and insert red test lead to RPM/Temp＋/Ω/V/ terminal. Set FUNCTION Switch to " " and press Select Key until " MΩ " appears on LCD. If the resistor to be measured is connected in a circuit, turn off power to the circuit and discharge the all capacitors. Then, disconnect one side of the resistor. Connect test leads to the resistor (or circuit) to be measured. Read the measurement value on LCD. After finishing the measurement, set FUNCTION Switch to "OFF".

Do not measure voltage in position. This will cause electrical shock hazard to the operator and/or serious damage to the instrument. In case in-circuit resistance is measured, turn off power to the circuit being measured and discharge the all capacitors. Discharge high-capacity capacitor through appropriate resistance load. Read "3. SAFETY PRECAUTIONS" carefully before measurement.
