3. SAFETY PRECAUTIONS
Correct knowledge of electric measurements is essential to avoid unexpected danger such as operator's injury or damage to the instrument. Read the following precautions carefully for safety measurements.
3-1. WARNINGS
WARNING 1. Checks of the Instrument and Test Leads
Before measurement, check if there are no damage to the instrument and the test leads. Dust, grease and moisture must be removed.
WARNING 2. Prohibition of High Power Line Measurement
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 30V AC or 42.4V DC, and ground goes up to 0.5mA or more.
WARNING 3. Warning for High Voltage Measurement
Even for Low Power Circuits of electric/electronic appliances, such as heating elements, small motors, line cords and plugs, High Voltage Measurements are very dangerous. To avoid electric shock hazard, pay careful attention not to touch any part of the circuit.
WARNING 4. Warning for Dangerous Voltage Measurement
For dangerous high voltage measurement, strictly observe the warnings below
(see Fig. 1).
●
●
●
●
●
Do not hold the instrument in your hands.
Keep safety distance from the circuit to be measured and the test leads not to touch the dangerous voltage.
Attach black and red alligator clips to the test lead pins.
Shut down the power of the circuit when connecting test leads to the circuit to be measured.
After finishing the measurement, shut down the power of the circuit again and discharge the all capacitors. Then, detach alligator clips (test leads) from the circuit.

4-1. RANGE Switch
Set RANGE Switch to an appropriate measurement range. When measuring uncertain voltage or current, firstly set the switch to the highest range enabling to measure an approximate value. Then, change the switch to an appropriate range.
Notes for the appropriate range selection
Voltage and Current : Place the pointer right side of the meter scale (between the center and the maximum scale).
Resistance : Place the pointer around the center of Ω scale.
WARNING
●
●
Before starting the measurement, confirm that the RANGE Switch is set to the correct position. Do not measure any voltage except in the DC.V and AC.V ranges to avoid electric shock hazard and serious damage to the instrument.
To avoid electric shock hazard or serious damage to the instrument, detach test leads from the measuring circuit before changing RANGE Switch to another position.
4-2. Meter Scale (How to read)
Ω scale
DC/AC scale
Common use for;
DC Voltage (DC.V)
AC Voltage (AC.V)
DC Current (DC.mA/A)
TEMP( ℃) scale Fig. 6
1. DC/AC Scale : AC/DC Voltage, DC Current
(V, μA, mA, A)
Select appropriate scale from "0 - 6", "0 - 12", or "0 - 30" according to the selected measurement range applying the certain multiple.
Examples :
120V DC range : Read "0 - 12" scale multiplying by 10.
60 μA DC range : Read "0 - 6" scale multiplying by 10.
600mA DC range : Read "0 - 6" scale multiplying by 100.
2. Ω Scale : Resistance
( Ω)
Multiply the scale value by the measurement range value.
Examples : ×1 range : Read the scale value directly.
×100 range : Multiply the scale value by 100.
×1k range : Multiply the scale value by 1,000.
3. TEMP ( ℃) Scale : Temperature
( ℃)
Read the scale value directly.
4-3. Meter Mirror (How to see the pointer)
The mirror to help the correct reading avoiding the reading error. Read the meter scale from the position that the meter pointer and its image in the mirror overlap each other. This position is directly above the meter pointer.
Meter scale must be read viewing the pointer from directly above, but the clearance between the pointer and the meter scale often causes reading error if the point of view is moved off to the side.
4-4. Zero Adjustment Screw
Use to take zero adjustment in Voltage and Current measurements. Check if the meter points to "0" line on the left side of DC/AC scale before starting the measurement. If it is not on the line, turn Zero Adjustment Screw until the meter points to "0". This adjustment is necessary for accurate reading.
4-5. 0 Ω Adjustment Knob
Use to take 0 Ω adjustment in Resistance and Temperature measurements. Refer to "5-5. Resistance Measurement ( Ω)" and "5-6. Temperature Measurement (℃ )" for details.
4-6. Input Terminals ・Test Leads
Insert black test lead to −COM terminal, and insert red test lead to ＋ or 12A terminal.
NOTE : Insert red test lead to 12A terminal for 12A DC measurement. For the other measurements, connect it to ＋ terminal.
