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

６．HOW TO MAKE MEASUREMENT
6-1 Current 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.
●Keep your fingers and hands behind the barrier during measurement.
CAUTION
● When handling the clamp sensor, exercise caution not to apply excessive shocks or
vibration to the sensor.
●
M
aximum measurable conductor size is MODEL2000A 6mm / MODEL2001A
10mm in diameter.
6-1-1 DC Current Measurement
(1)The Function Selector Swith to the " A" position.
("DC" and "AUTO" marks are shown on the top of the display.)
(2) Turn the 0(Zero) ADJ knob to set the reading of the multimeter to zero. (If this zero
adjustment is made incorrectly, measurement errors will result.)
(3) Adjust one of the conductors to the center of the clamp sensor's arrow.
( When the position of the conductor is not at the center of the arrow, the error
occurs.)
Measured value is shown on the display.
Note: When current flows from the upside to the underside of the instrument, the polarity
of the reading is positive (+). Otherwise, the polarity of the reading is negative (-).
6-1-2 AC Current Measurement
(1)Set the Function Selector Switch to " A."
("AC" and "AUTO" marks are shown on the top of the LCD.)
(2) Adjust one of the conductors to the center of the clamp sensor's arrow.
( When the position of the conductor is not at the center of the arrow, the error
occurs.)
Measured value is shown on the display.
Note: Unlike DC current measurement, zero adjustment is not necessary. There is not
polarity indication either.
6-2 Voltage 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 battery compartment cover removed.
●Keep your fingers and hands behind the protective fingerguard during measurement.
6-2-1 DC Voltage Measurement
(1)Set the Function Selector Switch to " V."
（"DC" and "AUTO" marks are shown on the top of the LCD.）
(2) Connect the red test lead to the positive (+) side of the circuit under test and the
black test lead to the negative (-) side. Measured voltage value is shown on the
display.
When the connection is reversed, "-" is shown on the display.

７．OTHER FUNCTIONS
7-1 Auto-Power-Save Function
NOTE
A small amount of current is consumed even in the power-save state. Make sure
to set the Function Selector Switch to the OFF position when the instrument is not
used.
This function helps to avoid unwanted exhaustion of the batteries because of
leaving the instrument powered on and extend battery life. The instrument
automatically shifts to the power-save state about 10 minutes after the last
Function Selector Switch or other switch operation.
To return to the normal state: Turn the Function Selector Switch or press the
Data Hold Button twice to exit the power-save state and enable measurement
functions.
7-2 Data Hold Function
This is a function to freeze a measured value on the display. Press the Data
Hold Button once to hold the current reading. In this data hold state, the reading
is held even if input varies. "H" and " " marks are shown on the LCD instead
of "AUTO" mark.
To exit the data hold state, press the Data Hold Button again.
7-3 Range Hold Function
The instrument defaults to auto-ranging ("AUTO" is shown on the LCD).
Pressing the Range Hold Button enables manual selection among measurement
ranges（" " mark is shown on the LCD instead of "AUTO" mark）
Press the Range Hold Button to select a higher range.
To switch from manual range selection to auto-ranging, press down the Range
Hold Button for about one seconds, or turn the Function Selector Switch to
another position before setting it back to the current range.
８．BATTERY REPLACEMENT
WARNING
● In order to avoid possible shock hazard, always disconnect the test leads from
the circuit under test and set the Function Selector Switch to the OFF position
before trying to replace the batteries.
CAUTION
● Do not mix new and old batteries.
● Install batteries in the orientation as shown inside the battery compartment,
observing correct polarity.
When the battery voltage warning mark "BATT" is shown on the top left corner of the
LCD, replace the batteries. Note that the display blanks and "BATT" mark is not
shown if the batteries are completely exhausted.
(1) Set the Function Selector Switch to "OFF."
(2) Remove the instrument from the holster.
(3) Loosen the battery-compartment-cover-fixing screw on the lower back of the
instrument.
(4) Replace the batteries with two new R03 (UM-4) 1.5V batteries.
(5) Put the battery compartment cover back in place and tighten the screw.
