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 8.4 V battery. But also a line

4
operation is possible using a power adapter
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 ST2822D/E is
rechargeable. Do not charge non-
rechargeable batteries.

Introduction
ST2822D/E is designed for measuring inductance,
capacitance and resistance of components. The
instrument can be powered by an 8.4V rechargeable
battery or external power adapter. This meter is not
only applicable to the application occasion of bench
meters but also conveniently used in the flow and
handheld measurement occasions.
ST2822D/E provides the primary parameter of up to
40,000 readings, secondary parameter of 0.0001
reading resolution, maximum measuring frequency up
to 100kHz, constant internal resistance of 100Ωand
three optional testing levels. 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 unimaginable up to 0.1%.
Front panel push buttons maximize the convenience
of function, such as FREQ, LEV, TOL and RATE.
Tolerance mode can sort components, record mode
aid to capture readings, convenient open/short clear
function improve the measuring accuracy, utility menu

10
help you easily take the selections of the key tone,
auto power-off and storage.
ST2822D/E is 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.

150mA, 4mm.

14
NOTE: Use with included power adapter only or
purchase the specified adapters from Sourcetronic.
Use with improper power adapters may damage
instrument.
NOTE: Internal battery supply will be
automatically cut off when external power is
connected. If the battery is rechargeable (ST2822D/E),
the external power will charge the battery
simultaneously. ST2822D/E is equipped with 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 instrument can charge the
battery (ST2822D/E), please be sure that the
polarity matches the (+) and (-) labels as indicated
inside the battery compartment and the battery is
rechargeable. DO NOT charge a 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”.
