OVERVIEW

This operating manual covers information on safety and cautions. Please read the relevant

information carefully and observe all the Warnings and Notes strictly.

Digital multimeter model UT61B is an auto ranging multimeter. The meter can measure AC/

DC Voltage and Current, Resistance, Diode, Continuity buzzer, Capacitance, Frequency, and

temperature. In addition to the conventional measuring functions, there is a RS232C or

USB standard serial port, data hold, relative mode, peak measurement, low battery display,

display backlight and sleep mode.

UNPACKING INSPECTION

Open the packaging of the meter and inspect to see any missing parts.

SAFETY INFORMATION

Meter UT61B complies with the standard IEC/EN61010-1, in pollution degree 2, overvolt-

age category (CAT III 1000V, Cat IV 600V) and double insulation. Use the meter only as

speciﬁed in this operating manual, otherwise the protection provided by the meter may be

impaired.

• Before using the meter inspect the case. Do not use the meter if it is damaged or the

case (or part of the case) is removed. Look for cracks or missing plastic. Pay attention

to the insulation around the connections.

• Inspect the test leads for damaged insulation or exposed metal. Replace damaged test

leads with identical model number or electrical speciﬁcations before using the meter.

• Replace the battery as soon as the battery indicator “ ” appears. With a low

battery, the meter might produce false readings that can lead to electric shock and

personal injury.

• Do not use or store the meter in an environment of high temperature and humidity.

The performance of the meter may deteriorate after dampened.

• Disconnect circuit power and discharge all high voltage capacitors before testing

resistance, continuity and diodes.

• Do not apply more that the rated voltage, as marked on the meter in order to avoid

possible electric shock or personal injury and avoid possible damage to the meter.

• Do not change the measuring range during the testing as it causes to damage the

meter.

• When the meter working at an effective voltage over 60V in DC and 30Vrms in AC,

special care should be taken

• When each measurement has been completed, disconnect between the test leads and

the circuit under test connection, then turn the meter power off and remove the test

leads away from the input terminals of the meter

• The internal circuit of the meter shall not be altered at will to avoid damage of the

meter and any accident

• Soft cloth and mild detergent should be used to clean the surface of the meter when

servicing. No abrasive and solvent should be used to prevent the surface of the meter

from corrosion, damage and accident.

• The meter is suitable for indoor use.
