I. Overview
UT121A/UT121B is a pocket-sized smart multimeter, it can identify functions and ranges
automatically according to the input signal, reducing operating difficulty effectively and
improve work efficiency. The EBTN display screen (UT121B) allows user to obtain clear
readings at maximum angle. This multimeter conforms to safety standards and is set
with all-featured overload protection, ensuring users to perform safe operation in
CAT III 600V locations. Designed with special appearance and function configurations,
UT121A/UT121B is a suitable measurement tool for entry-level and residential users.
II. Features
1. Stylish appearance, ultrathin design, large display screen.
2. Entering automatic signal recognition interface when powered on, i.e., resistance,
AC/DC voltage, continuity and other functions.
3. Displaying ambient temperature in auxiliary display screen when turned on.
4. NCV detection of electromagnetic field strength and circuit continuity.
5. Recognizing live wire fast with indication sound and frequency display under LIVE
mode.
6. Protection against false detection, withstanding 600V (3.6kVA) impact at most, set
with overvoltage indication.
7. Large capacitance (60mF) measurement function (UT121B).
8. 10MHZ frequency and temperature measurement functions (UT121B).
9. Designed with large EBTN LCD and smart ADC at 3 times per second (UT121B).
III. Accessories
If any item in the package is missing or damaged, please contact your supplier immediately.

IV. Safety Information
Note the “Warning labels and sentences”. A Warning identifies conditions and procedures
that are dangerous to the user and that can cause damage to the Product or the
equipment under test.
The product is designed in accordance with EN61010-1/61010-2-030/61010-2-033,
Electromagnetic Radiation EN61326-1 Standard, and conforms to Double Insulation,
Overvoltage CAT III 600V and Pollution Class 2. Failure to follow operating instructions
can impair the protection provided by the product.
1. Check the product and test leads before use. Pay attention to any damage or abnormal
situation. Please stop use if test lead and casing insulation are damaged, or the LCD
displays nothing, or the product cannot work normally.
2. It is forbidden to use without rear cover or battery cover set in place. Otherwise it may
cause electric shock.
3. Keep fingers behind the finger guard and never make contact with exposed wire,
connector, input terminal not in use, or circuit being measured during measurement.
4. Set the functional switch to correct position before measurement. It is forbidden to
switch over during measurement to avoid product damage.
5. Do not exert AC/DC voltage over 600V between terminal and grounding to prevent
electric shock and product damage.
6. Use caution when working with voltages over 60V DC or 30Vrms AC.
7. Do not measure voltage or current over allowed value. Before measuring on-line
resistance, diode or continuity, please disconnect all powers in the measured circuit,
and discharge all capacitors completely, otherwise it can cause inaccurate measurement
result.
8. When the symbol “ ” appears on the LCD, please replace the battery in time to
ensure measurement accuracy. Remove the battery if the product is not used for a
long time.
9. Do not alter the internal wiring to avoid product damage and safety hazard.
10. Do not keep or use the product in environments with high temperature, high humidity,
strong electromagnetic field, or inflammable and explosive environments.
11. Please wipe the casing with wet cloth and cleaning agent, do not use abrasives or
solvents, so as to prevent casing corrosion and avoid product damage and safety
hazard.
