WARNING
● Never attempt to make any measurement, if any abnormal conditions are noted,
such as broken case, cracked test leads and exposed metal parts.
● Do not turn the Function Selector Switch while the test leads are connected to the
circuit under test.
● Do not install substitute parts or make any modification to the instrument. Return
the instrument to Kyoritsu or your distributor for repair or re-calibration.
● Do not try to replace the batteries if the surface of the instrument is wet.
● Always disconnect the clamp sensor and the test leads from the circuit under test
and switch off the instrument before opening the battery compartment cover for
battery replacement.
● Stop using the test lead if the outer jacket is damaged and the inner metal or color
jacket is exposed.
CAUTION
● Make sure that the Function Selector Switch is set to an appropriate position before
making measurement.
● Always make sure to place the test leads in the test lead holder before making
current measurement.
●Do not expose the instrument to the direct sun, extreme temperatures or dew fall.
● Be sure to set the Function Selector Switch to the "OFF" position after use. When
the instrument will not be used for a long period of time, place it in storage after
removing the batteries.
● Use a damp cloth and detergent for cleaning the instrument. Do not use abrasives
or solvents.
●Keep your fingers and hands behind the protective fingerguard during measurement.
Measurement Category:
To ensure safe operation of measuring instruments, IEC 61010 establishes safety
standards for various electrical environments, categorized as O to CAT IV, and called
measurement categories. Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a measuring instrument designed
for CAT III environments can endure greater momentary energy than one designed
for CAT II.
O
: Circuits which are not directly connected to the mains power supply.
CAT II : Electrical circuits of equipment connected to an AC electrical outlet by a
power cord.
CAT III : Primary electrical circuits of the equipment connected directly to the
distribution panel, and feeders from the distribution panel to outlets.
CAT IV : The circuit from the service drop to the service entrance, and to the power
meter and primary over-current protection device (distribution panel).
２．FEATURES
● Permits AC/DC current measurement up to 60A using a clamp sensor that comes
standard with the instrument
●Clamp sensor for ease of use in crowded cable areas and other tight places
● Permits current measurement with an open current-clamp sensor that does not require
opening and closing operations by the user
●Auto-power-save function
●Buzzer for easy continuity checking
●Data hold function to freeze the readings
●LCD with a 3400 count full scale bar graph
●Shock absorbing holster for ease of storage

５．PREPARATIONS FOR MEASUREMENT
（1）Checking battery voltage
Set the Function Selector Switch to any position other than the OFF position.
If the marks on the display is clearly legible without symbol
"BATT"
showing, battery
voltage is OK. If the display blanks or
"BATT"
is indicated, replace the batteries
according to section
8: Battery Replacement
.
NOTE
When the instrument is left powered on, the auto-power-save function automatically
shut the power off; The display blanks even if the Function Selector Switch is set to
a position other than the OFF position in this state. To power on the instrument,
turn the Function Selector Switch or press the Data Hold Button. If the display still
blanks, the batteries are exhausted. Replace the batteries.
（2）Make sure that the Function Selector Switch is set to the appropriate range.
Also make sure that data hold function is not enabled. If inappropriate range is
selected, desired measurement cannot be made.
（3）Install Test Lead to the Holster on the side of body
It is possible to measure with seeing the LCD Display keep
Test Lead installing to the Holster.

6-2-2 AC Voltage Measurement
(1)Set the Function Selector Switch to " V."
（"AC" and "AUTO" marks are shown on the LCD.）
(2) Connect the test leads to the circuit under test.
Measured voltage value is shown on the display.
6-3 Resistance Measurement
DANGER
● Never make measurement on circuits that are live.
● Never make measurement with the battery compartment cover removed.
●Keep your fingers and hands behind the protective fingerguard during measurement.
(1)Set the Function Selector Switch to "Ω／ ."
(2) Check that the display shows over-range. Short the test leads and check that the
buzzer beeps and the display reads zero.
(3) Connect the test leads to the circuit under test. Measured resistance value is
shown on the display. When the measured value is below about 30Ω, the buzzer
beeps.
Note: When the test leads are shorted, the display may read a small resistance value.
This is the resistance of the test leads.
If there is an open in either of the test leads, "OL" is shown on the display.
On the 340Ω range, " " is shown on the left side of the LCD.
6-4 Frequency Measurement
DANGER
● In order to avoid possible shock hazard, never make measurement on circuits with a
maximum voltage difference of 600VAC/DC or greater between conductors
(300VAC/DC or greater between a conductor and ground).
● Do not make measurement with the test leads connected to the circuit under test.
Never make measurement with the battery compartment cover removed.
● Do not make current measurement with the test leads connected to the circuit under
test.
●Keep your fingers and hands behind the protective fingerguard during measurement.
(1)Set the Function Selector Switch to "Hz."
(2) Measuring frequency of current:
Adjust one of the conductors to the center of the clamp sensor's arrow. Measured
value is shown on the display.
Measuring frequency of voltage:
Connect the test leads to the circuit under test. Measured frequency is shown on
the display.
Note: Measuring range of current frequency is 0-10kHz with minimum measurable input
of MODEL2000A 15A（Typ）/MODEL2001A 25A（Typ）.
Measuring range of voltage frequency is 0-300kHz with minimum measurable input
of 30V（Typ）.
When measuring frequency, do not attach the clamp sensor and the test leads to
the circuit under test simultaneously.
