SAFETY PRECAUTIONS
This instruction manual explains how to use your multitester SP-18D ,
safely.
Before use, please read this manual thoroughly. After reading it, keep it
together with the product for reference to it when necessary.
The instruction given under the heading ”
WARNING
” ”
CA TIU ON
”
must be followed to prevent accidental burn or electrical shock.
Warning Instruction for Safe Use
To ensure that the meter is used safely, be sure to observe th e
instruction when using the instrument.
Please be careful that the protection circuit may be undermined by
unjustifiable usage that does not follow the guidelines in the instruc -
t n mio anual.
11. .Never use the meter on the electric circuits that exceed 6 kVA
12. sPay special attention when measuring the voltage of AC 33 Vrm
(46.7 V peak) or DC 70 V or more to avoid injury.
13. tNever apply an input signals exceeding the maximum rating inpu
v ue.al
14. -Never use the meter for measuring the line connected with equip
ment (i.e. motors) that generates induced or surge voltage since it
may exceed the maximum allowable voltage.
15. .Never use the meter if the meter or test leads are damaged or broken
16. .Never use uncased meter
17. a aBe sure to use fuse of the specified rating or type. Never use
substitute of the fuse or never make a short circuit of the fuse.
18. eAlways keep your fingers behind the finger guards on the prob
when making measurements.
19. gBe sure to disconnect the test pins from the circuit when changin
the fun tic on or range.
10. e s t g Befor tar in meas t, keuremen ma sure t t e f n andha th un ioct
range are properly set in accordance with the measurement.
11. .Never use the meter with wet hands or in a damp environment
12 Never open rear case except when replacing batteries or fuse.. Do
not attempt any .alteration of original specifications
13 To ensure safety and maintain accuracy, calibrate and check th. e
tester at least once a year.
14 Indoor use. .
WARNING
PRECAUTION
1 byAvoid giving the tester any excessive shock or vibration
loading it on the motorbike and the like.
2 Keep off dust and moisture from the tester.
3 a a hDo not leave the tester for long time in places of hig
temperatrue (higher than 55 high humidity (highe ) a ℃ r
than 80 %), and dew condensation.

INSTRUCTION MANUAL Dempa Bldg., 4-4 Sotokanda 2-Chome
Chiyoda-ku, Tokyo, Japan
Thank you for purchasing a SANWA tester, Model SP-18D. You ar e
kindly requested to thoroughly read this manual before use fo r
safety. Especially, "SAFETY INFORMATION" and "MEASURIN G
PROCEDURE" are important. Keep this manual together with th e
tester not to lose it.
Measuring DCV
1 toSet the range selector knob
an appropriate DCV range.
2 Apply the black test pin to the
minus potential of measure d
circuit and the red test pin to
the plus potential.
3 Read the move of the pointer
by V and A scale.
WARNING
Confirm the range to use before measurement.
Preparation for Measurement
1 :Adjustment of meter zero position
Turn the zero position adjuster so that the pointer may alig n
right to the zero position.
2 Range selection:
Select a range proper for the item to be measured set the
range selector knob accordingly.
When determining a rmeasuring range, select such one fo
high ler vo tage th the an value be s asto mea ured as well
where the pointer of a meter moves to a considerable extent.
However, select the maximum range and measure in cas e
the extent of value to be measured can not be predicted.
NOTE
Measuring ACV ～
1 .Turn the range selector knob to an appropriate ACV range
2 Apply the test pin to the measured circuit.
3 V A VRead the move of the pointer by and scale. (Use AC 12
scale for 12 V range only.)
•Since sthis instrument employ
the means value system for it s
AC voltage measurement circuit ,
AC waveform other than sin e
wave may cause error.
•There hoccurs error under suc
frequencies other than specifie d
in the specification.
Measuring DCA
1 .Turn the range selector knob to an appropriate DCA range
2 e out m d c d a ly the black test toTak ea resu ir itcu an pp pin
the minus potential of meas-
ured circuit and the red tes t
pin to the plus potential.
3 Read the move of the pointer
by V and A scale.
WARNING
Connect the meter in series with the load.
Cut off.
Measuring Ω
1 Turn the range selector knob to an appropriate Ωrange.
2 0 soShort the red and black test pins and turn the Ωadjuster
that the pointer may align exactly to 0 . (If the pointer failsΩ
to swing up to 0 even when the 0 adjuster is turnedΩ Ω
clock )wise fully, replace the internal battery with a fresh one.
3 dApply the test pin to measure
resistance.
4 Read the move of the pointer by
Ωscale.
Note: + - sThe polarity of and turn
reverse to that of the test pins
when measurement is done in
Ωrange.
Note: Be sure to use the same rated fuse. In case a fuse other
than the same rated one (see “SPECIFICATIONS“) is
used, error in indication occurs and/or circuit protection
is made unable.
Note: Operating voltage of range for this tester is 3 V and,Ω
accordingly, operator can make lighting test of LED.
X10 range is optimum for the test.
WARNING
Do not measure a resistance in a circuit where a
voltage is present.
Battery Test ,
1 .Set the selector knob to or
2 )Apply the black test pin to the (-
battery terminal and red test pin to
the (+) battery terminal.
3 m e i rRead the ov of the po nte
or scale.
•range: 20 loadΩ
For measure the cylindrical typ e
battery (R03, R6, R14, R20, LR03 ,
LR6, LR14, LR20, etc.)
•range: 60 k loadΩ
For measure the button type battery (SR43, SR44, LR43 ,
LR44, PR41, PR44, etc.)
Measuring Capacity µF
1 orSet the range selector knob to µF X1
µF X100.
2 Measure capacitance by applying the
test pin to the capacitor to be mea sured
after adjustment made in th 0 Ω e
same manner as in the resistanc e
measurement.
3 eThe pointer moves full scale by the charge current to th
capacitor. However, the pointer starts gradual returning from a
certain point. Read the indicated maximum value on µF scale.
Note: rBe sure to short circuit the both ends of the capacitor fo
discharge prior to the initial measurement or in such cas e
to measure after the measurement was once made.
Note: .Pay due attention to the polarity (+ and -) of the capacitor
(Connect side of the capacitor to black test pin of th + e
tester.)

case and remove it.
2 -Hand strap is attached to con
necting point.
3 dPut back the rear case was an
fix it with the screw.
MAINTENANCE
How to Replace Battery
1 rLoosen the screw fixing the rea
case and remove it.
2 Replace R6 (UM-3) dry battery.
3 itPut back the rear case where
was and fix it with the screw.
How to Replace Fuse
If an overload above lighting voltag e
(about 100 V) is applied to DC A
and n t f is wn toΩra ges, he use blo
prot t the circuit.ec
1 .Loosen the screws fixing the rear case and remove it
2 .Pull out the fuse out of holder on the circuit board and replace it
3 .Put back the rear case where it was and tighten the screws
4 eCheck and see whether or not indications of respectiv
ranges are normal (check other parts for any failures).
WARNING
•Be sure to use the fuse in same rating (0.5 A/250 V)
so as to ensure safety and performance of tester.
•Do not absolutely use the fuse in different rating or
short-circuit fuse holder terminals with copper wire.
•When operator removes the rear case, do not touch
the internal parts or wire with hand.
