General Safety Overview
This instrument strictly complies with safety standards of IEC61010-1, EN61010-2-030, pollution level II,
over voltage CATI 1000V, CAT II 300V and double insulated during design and manufacturing. It is IP65
waterproof and dustproof. In case the meter is not used properly as instructions, the protection provided
may be weakened or lost.
 Please use the dedicated UNI-T power supply wire appointed to the local region or country for this
product, and check if there is any metal part exposed or insulating layer damage.
 This product is grounded through the power supply ground wire. To avoid electric shock, grounding
conductors must be connected to the ground. Please be sure that the product is properly grounded
before connecting to the input or output of the product. The signal ground wire of the rear panel is the
same as the ground potential.
 Please check the accessories and wires for any mechanical damage before usage. Please replace
the wire before use if it is damaged.
 Please notice rated operating range and product marks. Never input over-range voltage into any
terminal or ground point of this product.
 When measuring, do not touch any exposed wires, connectors, unused inputs or the circuits being
measured. When measuring the voltage higher than 60V (DC) or 30V (AC), keep your fingers behind
the finger guard ring of the test leads to prevent electric shock.
 Do not operate the product if you suspect it is faulty, and please contact UNI-T authorized service
personnel for inspection. To avoid injury and damage, only trained personnel can perform the
maintenance program.
 Never touch exposed joints and components after connecting the power supply.
 Please do not operate the product when the instrument box opens. Do not change the internal circuit
of the meter.
 Only use fuse that appointed to this product.
 Use appropriate overvoltage protection to ensure that there is no overvoltage (like caused by lightning),
otherwise it may cause electric shock.
 Do not use or store the meter in high temperature, high humidity, flammable, explosive and strong
magnetic field environments.
 Before measuring resistance, continuity, diode and capacitors, please disconnect the power and fully
discharge all high-voltage capacitors.
