checking high power equipment, no operation mistake
should be committed. Remember a circuit tester needs
periodical
inspection
and calibration to maintainit in good
condition. A tester known to be defective,or laid away
unused for many months must not be used to measure
a

generaldescription
Viewed in the light of a circuit tester measuring voltage,
current, resistance,
etc., the YX-360TR is no more than a
standard multitester in function. But the added
versatility
of performing asa transistor analyzer distinguishesit from
average
meters.
For the particulan of its bounds
of hidden
possibility, you can examine for yourself the specification
data along with the benefits and advantagesthe instrument
offers.
For all this, the YX-360TR is by no means a large-built
equipment, but it is alightweight and handy-sizeddeviceto
be seatedanywhereon your bench. As a matter of fact, it is
suitable for carrying service. From beginners to profes-
sionals, you can enjoy a good command of it so as to get
the best of the instrument on your original idea according
to your own servicedesigt,

features
All-purpose
function.
The YX-360TR will entertain you with expanded
vision
of application. Optional use of the connector readily
transfers the meter to a regular transistor tester to
directly read hrr (DC amplification factor) of transis-
tors for you to determineif they aresuitablefor circuit
use.Few testers
perform such
unique doubleservice.
Ability no less
better than a large-sized
tester.
Excellent resolution factor of 0.2mV and above, and
widened resistance measurement range reading from
0.2Q up to 20MQ, and that energized
by the small-size
internal batteries, compare the instrument favorably
with a bulky test gear.
Seriescondenser
terminal (OUTPUTI.
Applied use of this extra terminal serves
to check TV
circuits for detecting AC signals with DC element
present
mixed isolated.
3-volt internal battery power.
It is impossiblefor a usualhandy testerwith a 1.S-volt
battery built - in to check the linear continuity of
semiconductorslike LED whose
forwardvoltage
exceeds
1.5V, being unable to read either their forward or
backwald resistance. In this respect,
the 1.s-volt bat-
terieslined up in series
spreadthe measurementrange
of
semiconductors.
One-handed
operation control and rational arrangement
of ranges.
All measurementsare controlled by a single
knob. Into
the bargain,
the 1000V DC and AC ranges
lie adjacent
eachother on the selector
switchboard
to evade
possible
danger caused by misplacedrange selection. In most
testersare
found theserangesadjoined
at the ohm range,
and there is a fair chanceof the circuit resistors being
burnt out rendering the instrumentout of service.
[n the
worst case,
it might bring on seriousaccident to the
operator.
Non-skidrubbersupport.
The rubbers supplied may be fitted in the pits on the
rear to tilt the meter to a convenient viewing angle on
the bench.They also
serveto prevent the meterto skid.
Glass
indicatorcover.
In considerationof the portable useof the instrument,
scratch-, heat- and dust-proof glass is used for the
protection of the indicator instead
of a soft metacrylic-
resincover.

5 Difference between voltage and current measurements.
Fig. 2-A is a standardvoltage
measurement,
where the
potential difference between 2 points is checked, for
which the meter is connected in parallel with load, while
-B checks
the current supplied
by power andconsumed
by load, where the meter is connected
in series
with the
circuit. Basically,
the differenceis whether the meter is
connected in parallel or in series
with ioad. The latter
connection accompanies
the trouble of cutiing openthe
circuit beingchecked.

In respect of measurement loss, the bigger the im-
pedance
of the meter(Zu) is, the smaller
is the current
(Iu) required for measurement
for the former, and, on
the contrary, the smaller
the impedance
of the meteris,
the voltage loss (drop) by IrxZu. (Ir - cunent
consumption) Thus, high accuracydata
areobtained by
the YX-360TR becauseof its very small current loss of
50uA for DCV and l25uA for ACV measurements
at
full scale, the voltage drop for current measurement
being250mV.
6 Voltagemeasurement
and internalimpedance.
There are 2 instances
of voltage
measurement
by parallel
connection. In caseof Fig. 2-A, there exists no high
impedance
corresponding
to Re of Fig. 3. Power
supply
sourcehas
its own internalresistance,
but it issosmall
as
can be ignoredfor voltagemeasurement,
and the loss
of
current consumption by a tester is practically nil the
meter reading
Ep. But, as can be noted in Fig.3, the
circuit condition changeson account of R4 present
and
200kQ of the tester connected
in parallel
for measure-
ment. Consequently, the
meter reads 3.77V against
the actual 4V resulting in
some
error.Therefore,when
measuring such a circuit,
where R is usuallyreplaced
with a tube or a transistor,

In Fig. 3, the circuit impedance

within -5% can be ignored, though the bigger the
internal

ACV measurement

The negative

and the positive lead to the OUTPUT terminal. A
condenser

in series
with the OUTpUT

to cut off DC element present
on the
circuit to read

Besides
checking AF output voltage, this terminal is
available
to detect signals
in TV servicing.For instance,
on the AC 50V rangeis detected the presence
of the

and, similarly, the presence

measurement
and 0O adjustment.
Resistance
measurement is powered by internal bat-
teries.
They wear by use
resulting
in reading
error of the
measuredvalue. For correct reading of resistance,
the
sensitivity
of the indicator must be adjusted
according
to
the voltage
suppliedby batteries. This is what is called
Gohm adjustmentfor the indicator
to read 0Q at full scale. It is
adjusted
in the following way:
As shown in Fig. 6, the range
selector
is placedat the range
being
used. With the + and -COM ter-
minalsshorted
together,
thepointer
moving toward 0,il is adjusted by
turning 00ADJ to the right or left

dB scale.
dB (decibel) is measured in the same way as ACV
measurement
reading
the dB scale
instead.
Because the human ear is analogous to logarithmic
variation, the input/output ratio of an amplifier and
transistor
circuit is expressed
by logarithmicvaluedB to
savecomplicatedcalculation. For a coupledcircuit of a
definite impedance,
power can be comparedby simply
expressingthe voltage (current) ratio by dB. The dB
scale
provided is graduated to read from OdBto +22d8
on the reference
of OdBat 0.7'75Y which is the voltage
when ImW is dissipated
across
600C2.
Most frequently, the input and output circuit im-
pedances
of audio amplifiers are not necessarily
stand-
when testing polarized resistance
like transistors
and diodes
(iunction
type), etc. So must it be when
testing
the leakage
of electrolyticcapacitors.
Current

Subject to the unit beingtested,
its impedance
changes
while measuringresistance
on account of the current
flowing in the unit, or the voltage
it is impressed
with.
Some abnormal state may be recognized due to self-
heating. It must be well noted for each ranse used
when, for instance.measuring
the DC resistance
of a
thin-wire coil and a bulk-type semiconductor like a
thermistor. The LI and LV scaies provided check

ardized for 600Q, and the dB values measured
by a
tester are nothing but voltage values read in dB
corresponding

when comparing

the trouble of making

when
it is
necessary
to convert
them into dB values.
For measurement on the I0V range, the dB scale
(-l0dB-+22d8) is read directly, buq when measured
on.the 50V range,
14dB is addedto the reading
on the

and on the l50V range,
2gdB is added.
Thus,
the

For a SiTR, this current is too small

the TR tested is passabie,
but if it goes

the TR

great deal subject to temperature. Be aware of

a l.5V dry cell

When measuring an unknown value, start with the

By virtue of the automatic protection circuit by Si
diodes placed in parallel with the meter movement,
the pulse current flowing into the movement is
absorbed
by them to safeguard
the moving coil from
getting
burnt.
A resistor may be burnt out on account of a high
voltage of about l00V misapplied. but it can be
replaced to restore the instrument to normal per-
formance. Resistors most liable to burn are |9Q
(R2l) for the Xl (Q) range,
and lQ (Rl2) for 0.254,
range. Refer to " supplementary data " at the
endof the manual.
For ahigh power circuit of more than 200V, sparking
can cause
someabnormality in the tester. Be
certain
to have the meter damagedrepaired and undergo
regular inspection and calibration by a warrantable
test
facility.
