1-2 Warning Instructions for Safe Use
1. Do not use the instrument if the meter or test leads look
damaged.
2. Be sure to use the specified fuse.
Neither use unspecified fuse nor short-circuit the fuse holder.
3. Do not apply higher voltage or current than the max. ratings
by each function. (See 1-3)
4. Use caution when working with voltages above 33 V ac rms,
46.7 V ac peak, or 70 V dc. These voltages pose a shock
hazard.
5. Do not use the meter to measure lines that may have
inductive voltage or surge voltage (e.g. motors) because the
input voltage may exceed the maximum rated voltage.
6. Never operate the meter with the case or battery lid removed.
7. Remove test leads from the meter before opening the meter
case for replacing the battery or fuse.
8. Never attempt to repair or modify the instrument, except for
battery and fuse replacement.
9. Do not use any unspecified type of test leads.
10.Keep your fingers behind the finger guards of the test leads
while measurement.
11.Connect the common test lead (Black) before you connect
the live test lead (Red). Disconnect the live test lead first.
12.Make sure the function, range, and terminals are properly set.
13.Do not switch the function, range, or the plugs to another
while measurement.
14.Do not operate the meter when it is wet or with wet hands.
WARNING
Incorrect measurement may be performed in a ferromagnetic or
intense electric field near transformers, high-current circuits, and
radio equipments.

[4] DESCRIPTION OF FUNCTIONS
4-1 Power Switch/Function Selector
Turn the switch to turn on/off the power and select a measuring
function. All segments of the LCD display will be turned on for 1
seconds after power-on, and then the meter will be ready to use.
Note:
The push buttons between the display and the function selector
work differently depending on how long you press. In this
manual, "press" means pressing momentary and "press and
hold for 1 sec. or more"means pressing longer.
4-2 Auto Power Saving
The Auto Power Saving mode turns the meter off automatically
after approximately 30 minutes of no activities. While the Auto
Power Saving mode, following activities set the auto power saving
back.
1) Function selector or push button operations
2)Non-OL readings in the Ωfunction, diode test, or continuity
check, non-zero readings in the Duty cycle/Frequency
measurement functions, or significant measuring readings of
above 512 counts in the other function ranges
While data communication to your PC is in use, Auto Power
Saving mode will be temporarily cancelled.
4-2-1 How to get back from theAuto Power Saving
Press the SELECT, RANGE HOLD, △REL、or HOLD button, or
disconnect theobject to measure and turn the power switch off and then
back on, and select a function before connecting the object.

―10 ―― 9 ―
4-2-2 How to disable the Auto Power Saving
Press the SELECT button while turning the meter power on.
Release the SELECT button after is turned off. (All
segments of the display turn on after power-on.) Then the meter
will be ready to use.
Turn the power switch OFF and then back on to resume.
Note:
Even in the Auto Power Saving mode, approx. 50µA will be
consumed. When in the auto power saving mode, intense
light like the direct sunlight into the optical communication unit
on the back of the DMM increases the consumption current.
Mount the attached light shielding magnet cap on the optical
comminucation unit connector when not in use. Always turn the
power switch to the OFF position when the meter is not in use
for a long time.
4-3 Low Battery Indication
Decreasing the internal battery voltage to approx. 7V due to
wearing down turns on the indicator on the LCD display.
Replace the battery with new one when the indicator turns on.
Use under "Low Battery" may cause malfunctions.
4-4 Measuring Function Selection
At each position of the function selector, press SELECT button
(⇒) to select measuring functions as follows.

Note:
The last selection of each function will be saved as power up

4-5 Range Hold
Press the RANGE HOLD button to select manual-ranging, and the
meter will remain in the range it was in. ( turns off.) In
the manual-ranging mode, press the button again to step through
the ranges. Select an appropriate range making sure units and
decimal point positions. To resume auto-ranging mode, press and
hold the button for 1 second or more.
Note:
Manual ranging mode is not available in the Hz functions.
4-6 Data Hold
Press HOLD button to freeze present reading for later view. (
indicator turns on.) Input fluctuation will not reflect on the indicated
value. Press the HOLD button again to disable the data hold
feature and go back to the normal measurement mode. (
indicator turns off.)
Note:
Function changes or functional operations will cancel the data hold
feature.
4-7 Beeper Control
Press the RANGE HOLD button while turning the meter power on
to disable the beeper. Release the RANGE HOLD button after
is turned off. (All segments of the display turn on right after power-
on.) Then the meter will be ready to use. Turn the power switch
OFF and then back on to resume.
Note:
The beeper for the continuity check and the plug improper
connection warning will not be disabled.

―12 ―― 11 ―
4-9 Test Leads Improper Connection Warning
The meter beeps as well as displays “InEr” to warn the user
against possible damage to the meter due to test leads improper
connections to the , or input jacks when other function
(like voltage function) is selected. (Temperature measurement
function is an exception.)
Note:
“InEr” warning may be indicated due to weak battery even if the
test leads are connected properly.
4-10 Relative Measurement
Press the △REL button to activate the relative measurement
mode and △indicator turns on. The relative measurement
mode offsets the meter to display relative values against
a reference. The meter displays its readings subtracting
the reading at the moment the △REL button is pressed.
Press △REL button again to exit the relative measurement
mode. This function works only on the main display.
4-11 Terms
Analog bar graph
The analog bar graph provides a visual indication of
measurement like a traditional analog meter needle.
Average sensing RMS calibrated
RMS (Root-Mean-Square) is the term used to describe the
effective or equivalent DC value of an AC signal. Most digital
multimeters use average sensing RMS calibrated technique to
measure RMS values of AC signals. This technique is to obtain
the average value by rectifying and filtering the AC signal.
The average value is then scaled upward (calibrated) to read
the RMS value of a sine wave. In measuring pure sinusoidal
waveform, this technique is fast, accurate and cost effective.
In measuring non-sinusoidal waveforms, however, significant
errors can be introduced because of different scaling factors
relating average to RMS values.

USB Optical Communication Unit
(KB-USB7)
Optical Communication Unit Connection
4-8 PC (Personal Computer) Interface
The instrument equips with an optical isolated interface port at the
meter back for data communication. KB-USB7, dedicated USB
optical communication unit (separately available), and PCLink7,
dedicated software, allow you to transfer real time readings and
internally logged data to your PC. For more information, see the
"HELP" for PCLink7 (PC linkage software).
Note:
Intense light like the direct sunlight into the optical communication
unit on the back of the DMM increases the consumption current.
Mount the attached light shielding magnet cap on the optical
comminucation unit connector when not in use.

The display will show the forward voltage drop (forward
biased).
*
Forward biased voltage drop for a good silicon diode is
between 0.400V to 0.900V. A reading higher than that
indicates a defective diode. A zero (or close to)reading
indicates a defective diode (shorted). An OL indicates a
defective diode (open).

Apply the red test pin to the cathode of the diode, and the
black one to the anode.
*
A reading [OL] for reverse biased voltage drop indicates
the diode is good. Any other readings indicate the diode is
defective (resistive or shorted).
