To prevent an electrical shock hazard to the operator and/or damage to the
instruments, read this instruction manual carefully before using the
Multitester. WARNINGS with the symbol on the Multitester and this
instruction manual are highly important.
Important Symbols
The symbol listed in IEC 61010-1 and ISO 3864 means "Caution
(refer to instruction manual)".
WARNING :
The symbol in this manual advises the user of an
electrical shock hazard that could result in serious injury or even
death.
CAUTION :
The symbol in this manual advises the user of an
electrical shock hazard that could cause injury or material damages.
Do not measure High Power Line that might exceed 2kVA. Measurement on
High Power Line is very dangerous. It sometimes includes High Surge
Voltage that could cause dangerous arcs of explosive short in the instrument
and could result in serious injury to the operator. When measuring high
voltage, even for Low Power Line (Low Energy Circuit), take extra care to
avoid electrical shock hazard and/or damage to the instrument.
Thank you for purchasing KAISE "MODEL KF-20 ANALOG MULTITESTER". To
obtain the maximum performance of this instrument, read this Instruction Manual
carefully, and take safe measurement.
Inspect the instrument and acessories for transport damage. If there is any
damage or missing items, ask your local dealer for replacement.
Confirm that the following items are contained in the package.

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 cleansing
fluid like gasoline or benzine. If necessary, use silicon oil or
antistatic fluid.
Avoid the multitester from hard mechanical shock or vibration,
high temperature and strong magnetic field.
Remove the batteries when the multitester is out of use for a
long time. The exhausted batteries might leak electrolyte and
corrode the inside.

Measurement exceeding the specified maximum values of each measurement
range is prohibited.
Always confirm that
RANGE
Switch is set to the correct position. Do not measure
voltage in DC-mA,
Ω
and BAT. ranges.
Detach test leads from the measuring circuit before rotating
RANGE
Switch or
opening rear case for battery or fuse replacement.
WARNING
Detach test leads from the circuit before rotating
RANGE
Switch to avoid electric
shock hazard and serious damage to the instrument.
Select suitable scale from "0 - 6", "0 - 12", or "0 - 30" applying certain multiple.
Reading examples :
Multiply the scale value depending on the measurement range.
Reading examples :
Read the scale directly.
For accurate measurement, read following notes carefully.
DC 0.3V range :
Read "0 - 30" scale multiplying by 1/100.
DC 120V range :
Read "0 - 12" scale multiplying by 10.
DC 60uA range :
Read "0 - 6" scale multiplying by 10.
DC 300mA range :
Read "0 - 30" scale multiplying by 10.
"x 1" range :
Read the scale directly.
"x 100" range :
Multiply the scale value by 100.
"x 1k" range :
Multiply the scale value by 1,000.
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.
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.
This instrument is applicable for Low Energy Circuit measurements only.
Do not use for High Power Line (High Energy Circuit) measurements such as
Distribution Transformers, Bus Bars and Large Motors.
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 Multitester, Test Leads, and any part of the circuit.
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.
For dangerous voltage measurement, strictly observe the warnings below.

Before measurement, confirm that meter points to "0". (zero-adjusted)
Select proper range referring to
「
5-1. 6-(1) Range Selection
」.
Read the meter from directly over the pointer.
Measurement in strong magnetic field or on iron plate causes reading error or
meter sensitivity wrong.
Once-a-year periodical calibration is necessary to maintain tolerance accuracy
and to take safety measurements.

Set the switch to a desired measurement range.
To measure uncertain voltage or current, firstly measure the approximate
value at the highest range, then change the switch into the suitable range.
For correct voltage and current measurements, select the range to point the
right side of the meter scale. (between center scale and maximum scale)
For correct resistance measurement, select the range to point around the
center of
OHMS
scale.
