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.

4 tThe meter cover is treated with antistatic coating. Do no

wipe it hard or clean it with volatile solvent. Use sof a t

brush to remove dust.

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.
