INTRODUCTION

Thank you for purchasing a SANWA tester Model YX360TRF. You are
kindly requested to thoroughly read this manual before use for safety.
Especially, “SAFETY INFORMATION” and “MEASURING PROCE-
DURE” are important. Keep this manual together with the tester so as
no to lose it.

SAFETY INFORMATION

SPECIFICATIONS

The following are precautions to prevent accidents such as electrical
shocks.
Be sure to read them before using the tester.

Symbols

The following cautionary signs appear on the multitester and
in this manual.

Disobedience to instructions with this sign may lead to trouble
with the tester and accidents such as electrical shock.

This sign cautions that high voltage is applied to parts marked
with it.

Precautions for Safety Measurement

To ensure that the meter is used safely, follow all safety and operat-

ing instructions.

1

1. Never use the meter on the electric circuits that exceeds 3kVA.

1

2. Pay special attention when measuring the voltage of AC 33 Vrms

(46.7V peak) or DC 70V or more to avoid injury.

1

3. Never apply input signals exceeding the maximum rating input

value.

1

4. 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.

1

5. Never use the meter if the meter or test leads are damaged or broken.

1

6. Never use an uncased meter.

1

7. Be sure to use a fuse of the specified rating or type. Never use a

substitute of the fuse or make a short circuit of the fuse.

1

8. Always keep your fingers behind the finger guards on the probe

when making measurements.

1

9. Be sure to disconnect the test pins from the circuit when changing

the function or range.

10. Before starting measurement, make sure that the function and

range are properly set in accordance with the measurement.

11. Never use the meter with wet hands or in a damp environment.
12. Never use test leads other than the specified type.
13. Never open the case except when replacing batteries or fuses. Do

not attempt any alteration of original specifications.

14. To ensure safety and maintain accuracy, calibrate and check the

meter at least once a year.

15. Indoor use only.

MEASURING PROCEDURE

Measuring DCV

1

Set the range selector knob to

an appropriate DCV range.

2

Apply the black test pin to the

negative potential, and the red

test pin to the positive poten-

tial of the circuit.

3

Read the movement of the

pointer by V and A scale.

WARNING

Confirm the range of use before measurement.

Preparation for Measurement

1

Adjustment of meter zero position:

Turn the zero position adjuster so that the pointer may align

right to the zero position.

2

Range selection:

Select a proper range for the item to be measured and set

the range selector knob accordingly.

When determining a measuring range, select a one higher

voltage than the value to be measured as well as where the

pointer of a meter moves to a considerable extent.

However, select the maximum range and measure in case

the extent of value to be measured can not be predicted.

NOTE

Measuring ±DCV (NULL)

1

Set the range selector knob to

an appropriate ±DCV (NULL)

range.

2

Turn the 0

adjuster so

exactly to 0 by ±DCV scale.

3

Apply the black test pin to the

negative potential side, and

the red test pin to the positive

potential side of the circuit.

4

Read the movement of the pointer by ±DCV scale.

Fig. 3

Measuring ACV 

1

Turn the range selector knob to an appropriate ACV range.

2

Apply the test leads to the circuit to be measured.

3

Read the movement of the pointer by V and A scale. (Use

AC 10V scale for 10V range only.)

•Since this instrument provides

the mean value system for its AC

voltage measurement circuit, AC

waveform other than sine wave

may cause an error.

•Errors occur under such frequen-

cies other than those in the speci-

fication table.

Measuring DCA

1

Turn the range selector knob to an appropriate DCA range.

2

Take out the circuit to be measured and apply the black test

pin to the negative potential,

and the red test pin to the

positive potential of the cir-

cuit.

3

Read the movement of the

pointer by V and A scale. 

WARNING

Connect the meter in series with the load.

Cut off.

Fig. 4

Fig. 5

Measuring 

1

1

Turn the range selector knob to an appropriate 

1

range.

2

Short the red and black test pins and turn the 0

1

adjuster so

that the pointer may align exactly to 0

1

. (If the pointer fails

to swing up to 0

1

even when the 0

1

adjuster is turned

clockwise fully, replace the internal battery with a fresh one.)

3

Apply the test pin to measur

resistance.

4

Read the movement of the point-

er by 

1

scale.

Note

:The polarity of + and - is

reverse to that of the test

leads when measurement is

done in 

1

range.

Note

:How to replace battery.

1

Loosen the screws fixing the rear

case and remove it.

2

Replace R6 (UM-3) to fresh dry

batterise.

3

Put back the rear case where it

was, and fix it with the screws.

Note

:Be sure to use the same rated

fuse. In case a fuse other than

the same rate (see “SPECIFICATIONS“) is used, an error in

indication occurs and/or circuit protection is made unable.

WARNING

Do not measure the resistance in a circuit where

a voltage is present.

Fig. 6

Fig. 7

Measuring Capacity (C)        

1

Set the range selector knob to C(μF) .

2

Measure the capacitance by applying

the test pin to the capacitor to be meas-

ured after the 0

1

adjustment is made

in the same manner as in the resist-

ance measurement.

3

The pointer moves full scale by the charge current to the

capacitor. However, the pointer gradually starts returning to its

original position. Read the indicated maximum value on C(μF)

scale.

Note

:Be sure to short circuit the both ends of the capacitor for

discharge prior to the initial measurement or in such case

after the measurement is made.

Note

:Pay due attention to the polarity (+ and -) of the capacitor.

(C side of the capacitor to - side of the meter.)

Measuring AF Output (dB)        

dB (decibel) is measured in the same way as the ACV

measurement, but by reading the dB scale instead.

For measurement on the 10V range, the dB scale (- 10dB ~

+22dB) is read directly, but, when measured on the 50V

range, 14dB is added. On the 250V range, 28dB is added to

the reading on the scale, and on the 1000V range, 40dB

added.

Thus, the maximum dB readable is 22 + 40 = 62 (dB) meas-

ured on the 1000V range.

Note

:Cut direct current with a capacitor of 0.1μF or more when

measuring such signal as having direct current.

3

Connect the black test pin to the probe jack when a transis-

tor to be measured is NPN, and the red pin to the probe

jack for PNP transistor.

4

MAINTENANCE

How to Replace the Fuse

If voltageover 100V is applied

to DCA and 

1

ranges, the fuse

may blow out to protect

th

e

circuit.

1

Loosen the screws fixing the

rear case and remove it.

2

Pull the fuse out of holder on the

circuit board and replace it.(Fig. 11)

3

Put back the rear case where it was and tighten the screws.

4

Check and see whether or not indications of respective

ranges are normal (check other parts for any failures).

Storage and Other Precautions

1

Avoid giving the meter any excessive shock or vibration by

loading it on the motorbike, for instance.

2

Keep off dust and moisture from the meter.

3

Do not leave the meter for a long time in places of a high

temperature (higher than 55˚C), a high humidity (higher than

80%), and dew condensation.

4

The meter cover is treated with antistatic coating. Do not

wipe it hard or clean it with volatile solvent. Use a soft

brush to remove dust.
