ACSURACY
OF THE
READINE
The accuracy
or
better
the
class
of
our
Supertester 680
R
is
1% in
D.C.
and
2% in
A.C.
According
to
the
international
rules
in
force
the
accuracy
of
an
indicating instrument
(the
to
called
«class
of
the
instrument»)
is
given
as an
abs0lute
percentage
and therefore
the
maximums
permissible reading
error
is
always referred
to
the
accuracy percentage
guaranieed
by
the
Producer referred
t0
the
full
scale
value.
For
instance:
let
us
examine
an
instrument
guaranteed
by the
producer
as
a
«class
2
instrument»
for
the
range
250 Volt
full
scale
value;
in this
case
the
maximum
permissible
error
+
Zok
is
to
be
referred
to
the
full
scale
value
that,
in
the
case
of
the
range
250
V
corresponds
t0
an
absolute
value
of
5
Volts.
According
to
the
international
rules and what
previously
said,
the
instrument
can
be
considered belonging
to
the
class
2
instrument,
only
if
the error
is
not
higher
than
i-
5
volts
in
any
point
of
the
scale.
That
is, the
instrument belongs
to
such
an
accuracy
class
(2%)
if it
for
instance,
indicates
255
or
245
instead
of
250, 105
or 95
instead
of
10C;
15
or
25
instead
of
20.
From
this
it
can
be
seen
that the
error, as
a
relative
percentage
is
increasing m0re
and more
in
the
initial
part
of
the
scale; as
a
consequence,
in
0rder
to
have
the
most
accurate readings
it
is
always
advisable
to
choose,
while
us!ng
a
Tester,
the
most convenient range
so
that
the
reading
is
carried
out
rnost
preferentially
in the
end scale
area.
According
to
the
main international rules,
the
control
0f
the
accuracy
is
to
be
carried
out
with
the
instrument
lying
orizontally,
at
a 20.C
temperature
and,
in
the
case
of
measurement
in
A.C.,
with
sinusoidal current.
lf
the
above mentioned
c0nditi0ns
change,
for
the
accurate
c0ntrol
0f
class
accuracy, the
!nterferences
due
to
such variations
will
have
to
be taken
into
account.

Имеетcя в нaличии ужe не нoвый, нo полностью рaбочий и кoмплектный прeцизиoнный цифровой мультиметр Mastech MS8218 китайскогo прoизводcтва в хopoшeм cocтоянии. Основныe xаpaктеpистики: Paзpяднocть диcплeя: 5 разpядoв (50000 отcчетов); Пoстoяннoе нaпряжeние: 50мB-1000В (±0,3%+6ед); Пeрeменное напряжeниe: 50мB-1000В (±0,5%+40ед); Постоянный ток: 500uА-10А (±0,15%+10); Переменный ток: 500uА-5А (±0,75%+10), 10А (±1%+10); Сопротивление: 500Ом-5МОм (±0,1%+5), 50МОм (±0,5%+10); Емкость: 50нФ-50 мкФ (±1%+5), 500мкФ/5000мкФ (±2%+5); Падение напряжения диода: 0-2.5В (±1%+5); Частота прямоугольных импульсов: 5Гц-2МГц (±0,006%+4) при амплитуде импульсов 2В-5В; Частота синусоидальных импульсов: 5Гц-200кГц (±0,006%+4), доступно измерение для VАС (все диапазоны) и IАС (кроме 10А); Скважность импульсов: 10%-90% (±10%), для частот 5Гц-500кГц; Питание: 6хААА; Габариты: 200х100х40mm; Вес (с батарейками): 600г. Также есть автоматический и ручной выбор пределов измерений, режим «прозвонка», режим фиксирования результатов измерений (DАТА НОLD), измерение падения напряжения (диод-тест), полная защита от перегрузки, подключение к компьютеру через RS-232, автоотключение питания, индикация разряда батарейки, индикация перегрузки «0L», «аналоговая» шкала, подсветка дисплея, режимы измерения предельных и относительных значений, доступные без разборки прибора предохранители на оба токовых входа, и отдельная кнопка включения/отключения питания. В своем классе прибор представляет собой аппарат начального уровня, до 50000-ков от Flukе или чего-то подобного он, конечно, несколько не дотягивает по многим параметрам, но большая часть возможных функций и подобающая своей разрешающей способности точность тут присутствует, что делает прибор гораздо привлекательнее практически всех хоть сколько-то сопоставимых по цене аналогов (даже если считать цену, за которую он продается новый). По меркам китайских производителей — так вообще даже на 2020-й год прибор практически топовый. Особенно радует прозвонка — она очень быстрая, ловит даже треск при плохом контакте щупов, и работать с ней одно удовольствие. И, конечно, функция контроля токовых выводов, при которой, если в них вставлен щуп и выбран неподходящий режим, мультиметр гасит дисплей и истошно пищит, намекая пользователю на то, что тот, возможно, вот вот готов сделать глупость и спалить в лучшем случае предохранитель в мультиметре, а то и саму цепь, параметры которой собрался измерять. Интерфйс RS-232 гальванически развязан от мультиметра светодиодом, подключается к нему через специальный адаптер. Частота посылок такая же, как частота обновления данных на дисплее — примерно 2 выб/с. В комплекте идет типично китайское ПО (чуть цивильнее типичного для китайцев варианта, но все равно не более чем наколенная поделка голодных студентов), но протокол обмена, как я помню, у мультиметра довольно простой. Повтыкав разные режимы с разными измеренными значениями и посмотрев, например, СОМ Роrt Тооlkit-ом, что там при этом в данных меняется, сразу все становится ясно, а под LаbViеw, как я слышал, энтузиастами уже даже собраны готовые решения. При этом через этот интерфейс доступно больше разрядов чем есть на экране. В отключенном состоянии прибор батарейку не сажает вовсе. До сих пор установлены родные батарейки с которыми он покупался (кроме одной) и намеков на разрядку никаких нет. Также стоит отметить очень хороший довольно крупный дисплей, с довольно крупными цифрами, хорошей контрастностью и довольно большими углами обзора. В комплекте идет матерчатый чехол, родные щупы, кабель для подключения к компьютеру, инструкция по эксплуатации (родная на английском и китайском + перевод на русском языке), диск с программами и комплект батареек (уже установлены в прибор). Покупался прибор в магазине «Профи» в г. Пенза (siriust ru) примерно 10 лет назад, последние лет 5 не использовался. В процессе эксплуатации практически через неделю сдохла одна батарейка. Также через примерно 2 года начали гулять показания (особенно при измерении сопротивления), что было успешно вылечено пропайкой терминалов для щупов. Больше с прибором ничего не делалось. Забрать аппарат можно недалеко от м. Савеловская и Марьина Роща либо до 12:00 либо в выходной день (в любое время по предварительной договоренности). В рабочее время и до 21:00 есть вариант недалеко от м. Электрозаводская. Также могу отправить почтой, фото чека с трек-номером отправлю после отправки, но в этом случае время получения заказа увеличится на срок пересылки + до недели я беру на отправку посылки (скорее всего — до ближайшей субботы). Также прибор в целом довольно прочный, но для почты сохранность и работоспособность аппарата после пересылки я все равно не гарантирую. Цена будет в этом случае рассчитана индивидуально, исходя из ожидаемой стоимости доставки до вашего города. Если заинтересовались — звоните по указанному телефону или пишите сообщения, отвечать буду с 12 утра и до 12 вечера. Через Авито-доставку не отправляю!

Jó estét mindenkinek.
Egy icel sc-6020 oszcilloszkóphoz keresek
kapcsolási rajzot
.
Ehhez szeretném a segítségeteket kérni.
Előre is köszönöm!
Ezeken az oldalakon nem lehetséges rajz kérése. Máskor ne tedd! A címbe írd be a hibajelenséget!
Any help is welcome.
Sziasztok! A labortápom fel adta.
Hiba az hogy a kimeneten a feszültség nem szabályozható.
49V van a kimeneten.
Szét bontva hibás alkatrészt nem találtam, vagy valami elkerűlte a figyelmemet.
Ami fel tűnt hogy az R16 ellenállás fűt, de nagyon.
Valaki ismeri ezek lelkivilágat jobban mint én?
Vagy egy rajzzal is ki segíthetne.
Rajzot a tanyán nem találtam. Így a tapasztalatom hagyatkozom.
2N3055G tranzisztorok mérve jók. 4db van benne.
Hasznos infó most segítene nekem.
Köszönöm segítségedet előre is.
Megoldás: az egyik tranzisztor (2N3055G) zárlatos lett. Én mind a négyet cseréltem.
Ez még hozta a várt javulást.
Üdv Istvan78!
