Safety Guidelines
To ensure that you use this device safely,
follow the safety guidelines listed below:
This meter is for indoor use, altitude up to
2,000 m. For short-time outdoor use,
precautions should be taken to avoid direct
sunlight, water and moisture,
electromagnetic radiation, dust and
explosion.
The warnings and safety precautions should
be read and well understood before the
instrument is used.
Use the meter only as specified in this
manual.
Confirm that the circuits have been powered
off and all capacitors in the circuits been
discharged before measuring in-circuit
components.
Discharge all charging elements, such as
capacitors, before testing.
The power for the meter is supplied with a
single standard 9V battery. But also a line
operation is possible using a power adapter

5
of 12VDC/150mA. If a power adapter is
selected, please be sure to meet the safety
requirements of a relevant IEC standard.
The battery using in ST2822C is
rechargeable. Do not charge non-
rechargeable batteries.

Introduction
ST2822 series are designed for measuring inductance,
capacitance and resistance components. The
instrument can be powered by a 9V battery or external
power adapter. The meter is not only applicable to the
application occasion of bench meters but also
conveniently used in the flow inspect and handheld
measurement occasions.
ST2822 series provide the primary parameter of up to
40,000 readings, secondary parameter of 0.0001
reading resolution, the maximum measuring
frequency of up to 100kHz, constant internal
resistance of 100Ωand testing level of 0.6Vrms. The
auto range can rapidly display the measuring results
and automatically choose the desirable testing
parameters in accordance with components properties.
Its measuring accuracy is up to 0.25%.
Front panel push buttons maximize the convenience
of function and feature selection such frequency, rate
and L/C/R/Z selection. Tolerance mode can sort
components, record mode aid to capture readings,
convenient open/short clear function improve the
measuring accuracy, utility menu help you easily take

11
the selections of the key tone, auto power-off and
storage.
All ST2822 series are equipped with the function of
remote communication. The test data can be
transferred to PC through a Mini USB connection,
great for applications that require remote control and
data acquisition.

*Backlight is not included in ST2822.
NOTE: Refer to the adapter's label for input
parameters of it. Rated output parameters is 12VDC ，
150mA , 4mm.
NOTE: Use with included power adapter only or
purchase the specified adapters from Sourcetronic.

15
Use with improper power adapters may damage
instrument.
NOTE: Internal battery supply will be
automatically cut off since the normal supply of
external power. If the battery is rechargeable
(ST2822C), the external power will charge the battery
simultaneously. ST2822C is installed an independent
charging controller---charging control is still done even
at the state of power-off.
WARNING: Before connecting an external
power adapter, be sure that the polarity matches
the (+) and (-) labels as indicated inside the battery
compartment. If it is not installed correctly and
connected to an external power adapter, it might
cause severe damage to the instrument.
WARNING: If the battery is rechargeable
(ST2822C), please be sure that the polarity
matches the (+) and (-) labels as indicated inside
the battery compartment ant the battery is
rechargeable. DO NOT charge the non-
rechargeable battery!

Front Panel Buttons
With the exception of the power button, all front panel
buttons have specific colored labels on them. They
are all marked in black, blue, or orange color. Each
color has a specific representation, as described
below:
Black—the primary function，meaning that
function will be set or configured upon pressing it.
Orange—the secondary function, it means that
the function will be set or configured if that button is
pressed and hold down for 2 seconds.
Blue—the utility function, the function will be set
or configured if the UTIL button is pressed and hold
down for a long time. See “Utility Menu” section for
details.
NOTE: In the button operational instruction, we
will use the button name to express the button
operation without differentiating the type of button;
Pay attention to the difference between “long press”
and “press”.
