IV . Safety Information
Specifies the conditions and actions that may cause damage to UT261B.Caution:
Specifies the conditions and actions that may pose hazards to the User. Warning:
To prevent electric shocking or fire, it is necessary to comply with the following codes:
It is required to read through following safety instructions prior to operation or maintenance ；
Comply with local and national safety codes;

features/protective measures provided by the instrument may be affected;
Inspect the insulator of testing lead for damage or exposed metal; inspect testing lead for continuity
and replace the damaged testing lead.
Please take extreme caution when working with voltage higher than 30Vacrms, 42Vac Peak or 60Vdc,
for it may pose electric hazard.
Keep finger away from alligator clip contact and behind the finger protection device when using
alligator clip.
Adverse impact will be caused to the measurement by the impedance generated by the transient
current of extra operating circuit in parallel;
Please ensure the instrument operates normally prior to measuring dangerous voltage (30V ac rms,
42 V AC peak value or 60 V DC above)
Testing time should not exceed 10min when measuring the voltage 500V ~ 600V AC above;
Do not operate UT261B when removing any part;
Do not operate UT261B around explosive gas, steam or dust;
Do not operate UT261B in a wet place;
It is required to remove testing lead from the power and UT261B prior to replacing the battery.
