Ư/ OVERVIEW

ư/!SAFETY INFORMATION

Brand-new UT151 series are 2000-count handheld digital multimeters featuring remarkably

stable and reliable operations. They are designed with the large-scale integrated circuits and

dual integral A/D converter and also offer overload protection for all ranges. The series can

measure DC&AC voltage, DC&AC current, resistance, capacitance, diode, transistor,

temperature, frequency, battery and continuity, which make it a perfect solution for your work.

This instrument is designed and manufactured in compliance with: GB4793, IEC61010-1,

IEC1010-2-032, CAT.I 1000V,CATII 600V, Pollution Degree 2 and Double Insulation standards.

Warning

Please operate the instrument as specified in the manual, otherwise the protection offered

by the instrument would be compromised.

The red and black test leads should be inserted in the proper terminals and ensured with

good contact.

Switching the range

Use only the replacement fuse with the same model or identical electrical specifications.

1) Although the capacitance ranges have been protected internally, you still need to discharge

all tested capacitors so as to avoid any damage to the instrument or any measurement error.
