PREPARATION AND CAUTION
BEFORE MEASUREMENT
*Before making measurements,install the batteries two
LR-44 batteries can be used.
*Avoid using the POCKET PERSONAL D.M.M.in places
subject to high temperatures,humidity or excessive
vibration.
*Avoid using the POCKET PERSONAL D.M.M.in places
with rapid temperature variations.
*If the POCKET PERSONAL D.M.M.is used near noise
generating equipment,be aware that the display may
become unstable or indicate large errors.
* I f t h e f u n c t i o n m u s t b e s w i t c h e d d u r i n g a

MEASURING METHOD
*MEASURMENT OF DC VOLTAGE (DC-V)
(AUTO-RANGING)
(1)Set the function switch to "DCV".
(2)The"DC"mark will be displayed on the left side in the
display.
(3)Connect the test leads to the circuit to be measured,the
range will change automatically to the level that will
display the input voltage with the best resolution.
(4)The value indicated in the display window is the
measured value of voltage with proper decimal point and
annunciator indication.
*MEASURMENT OF AC VOLTAGE (AC-V)
(AUTO-RANGING)
(1)Set the function switch to "ACV".
(2)The "AC"mark is indicated on the left side in the display
window.
(3)Connect the test leads to the circuit to be measured,the
range will change automatically to the level that will
display the input voltage with the best resolution.
(4)The value indicated in the display window is the
measured value of voltage with proper decimal point and
annunciator indication.
*MEASURMENT OF RESISTANCE (Ω)
(AUTO-RANGING)
(1)Set the function switch to "Ω".
(2)Make sure all power is OFF in the circuit to be
measured.
(3)Connect the test leads to the circuit to be measured,the
range will change automatically,and will hold on the range
that will display the measures resistance with the best
resolution.
(4)The value indicated in the display is the measured value
of resistance with proper decimal point and annunciator
indication.
*MEASURMENT OF CONTINUITY CHECK
(
)
(1)Set the function switch to "
"
(2)Make sure all power is OFF in the circuit to be
measured.
(3)Set the function switch to "
"and the "
"mark is
indicated on the left side in the display.This is the
continuity check mode.In continuity mode,a buzzer sounds
when the resistance of the circuit to be measured is less
than approx.50ohms.
REPLACEMENT OF BATTERY
(1)When the batteries becomes exhaused or drops below
the operating voltage the "
" mark is displayed.
(2)Turn the function switch"OFF"and remove the test leads
from all test circuit,prior to installing fresh batteries.
(3)Remove the batteries by using the tip of RED test probe.
(4)Insert the two LR-44 or SR-44 into the battery case
making sure that proper polarity is observed.
Caution
Never use the BLACK test probe to avoid the short-circuit.
