Kaise KF-20 Instruction Manual

ANALOG MULTITESTER
INSTRUCTION MANUAL
KF-20
FOR SAFETY MEASUREMENTS!!
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.
WARNING
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.

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 carefully and
observe the following precautions for safety measurements.

3-1. WARNINGS

WARNING 1. Checks of Body and Test Lead
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.
WARNING 2. High Power Line Measurements Prohibited
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.
WARNING 3. Warning for High Voltage Measurements
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.
WARNING 4. Dangerous Voltage Measurement Procedures
For dangerous voltage measurement, strictly observe the warnings below.
(refer to fig.1)
Turn off the circuit to be measured.
1.
2. Plug black test lead to "- (COM)" terminal and red test lead into "+" terminal.
3. Attach black and red alligator clips to test lead pins.
Set RANGE Switch to desired DC or AC voltage range.
4.
5. Connect black alligator clip to - (earth) side and red alligator clip to + (positive)
side of the measuring circuit.
6. Do not hold Multitester and test leads in your hands. Keep safety distance
from power source or circuit to be measured not to touch the dangerous
voltage.
7. Turn on the circuit to be measured, and read the meter.
8. Turn off the circuit again. Detach alligator clips after confirming the meter
returns into "0".

3-2. GENERAL WARNINGS AND CAUTIONS

WARNING 1. Children and the persons who do not have enough knowledge
about electric measurements must not use this instrument.
WARNING 2. Do not measure the electricity naked or barefooted to protect
yourself from electrical shock hazard.
WARNING 3. Be careful not to get hurt with the sharp test lead pins.
CAUTION 1. 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.
CAUTION 2. Avoid the multitester from hard mechanical shock or vibration,
high temperature and strong magnetic field.
CAUTION 3. Remove the batteries when the multitester is out of use for a
long time. The exhausted batteries might leak electrolyte and
corrode the inside.

c. For correct resistance measurement, select the range to point around the
center of OHMS scale.
(2) Confirmation of the Range
Always confirm that RANGE Switch is set to the proper measurement range. To
avoid serious damage to the instrument, do not measure voltage in DC-mA, Ω
and BAT ranges.
WARNING
Detach test leads from the circuit before rotating RANGE Switch to avoid electric
shock hazard and serious damage to the instrument.

8. Measurement Accuracy

For accurate measurement, read following notes carefully.
Before measurement, confirm that meter points to "0". (zero-adjusted)
1.
Select proper range referring to 「5-1. 6-(1) Range Selection」.
2.
3. Read the meter from directly over the pointer.
Measurement in strong magnetic field or on iron plate causes reading error or
4.
meter sensitivity wrong.
5. Once-a-year periodical calibration is necessary to maintain tolerance accuracy
and to take safety measurements.
