International Electrical Symbols - UNI-T UT61B Operating Manual

Model: UT61B
• 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.
