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 automaticallyshut the power off; The display blanks even if the Function Selector Switch is set toa 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 stillblanks, 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.

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 thebuzzer beeps and the display reads zero.
(3)Connect the test leads to the circuit under test. Measured resistance value isshown 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

6-1-1 DC Current Measurement

6-1-2 AC Current 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 inputof MODEL2000A 15A（Typ）/MODEL2001A 25A（Typ）.
Measuring range of voltage frequency is 0-300kHz with minimum measurable inputof 30V（Typ）.
When measuring frequency, do not attach the clamp sensor and the test leads tothe circuit under test simultaneously.

７．OTHER FUNCTIONSCapped condition for CAT III environments

This instrument satisfies the marking requirement defined in the WEEE
Directive. This symbol indicates separate collection for electrical andelectronic equipment.

7-1 Auto-Power-Save Function

This marking means they shall be sorted out and collected as ordained in
DIRECTIVE.
This directive is valid only in the EU. When you remove batteries fromthis product and dispose them, discard them in accordance with domestic
law concerning disposal. Take a right action on waste batteries, because
the collection system in the EU on waste batteries are regulated.

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 ofleaving 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 theData Hold Button twice to exit the power-save state and enable measurement
functions.

7-2 Data Hold Function

DISTRIBUTOR

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" marks are shown on the LCD insteadis held even if input varies. "H" and "of "AUTO" mark.
To exit the data hold state, press the Data Hold Button again.

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 toanother position before setting it back to the current range.

８．BATTERY REPLACEMENTWARNING●In order to avoid possible shock hazard, always disconnect the test leads fromthe 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.

Kyoritsu reserves the rights to change specifications ordesigns described in this manual without notice and withoutobligations.

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 notshown 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.

ManualRange

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 calledmeasurement categories. Higher-numbered categories correspond to electricalenvironments 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 apower 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).
