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.
Place the pointer right side of the meter scale (between
the center and the maximum scale).
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.
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.

Internal Resistance : DC Voltage 20kΩ/V, AC Voltage 10kΩ/V
※NOTE 1 :
※NOTE 2 : Temperature measurement requires the optional 810-02 temperature probe.
Continuous measurement in 12A DC range is restricted up to 1 minute.
More than 1 minute interval is necessary for the next measurement.
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.
Before measurement, check if there are no damage to the instrument and the test
leads. Dust, grease and moisture must be removed.
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.
Detach test leads from the measuring circuit before changing RANGE Switch to
another position or removing rear case for battery or fuse replacement.

WARNING 7. Maximum Input Observance
WARNING 6. Correct Selection of Range Switch
WARNING 5. Warning for 12A DC 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.
Children and the persons who do not have enough knowledge
about electric measurements must not use this instrument.
Do not measure the electricity in naked of barefooted to
protect yourself from electrical shock hazard.
Be careful not to get hurt with the sharp test lead pins.
Away the instrument from hot and humid conditions like in
the car. Do not apply hard mechanical shock or vibration.
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.
Remove the battery when the instrument is out of use for a
long time. The exhausted battery might leak electrolyte and
corrode the inside.
