How to turn off the sound?

Hi, thanks for your question. The TM-510 multimeter does not have the function of turning off the sound alarm in order to more accurately prompt the user about the danger of electricity use during use.

Do these have fuse protection inside the multimeters?

Hi, thanks for your question. TESMEN TM-510 does not have the function of measuring current, so there is no fuse.

is there a way of turning of the auto mode if you want to keep it measuring one thing?

Hi, thanks for your question. The TM-510 multimeter only has automatic mode and cannot be switched.

Would this work to test an electric fence ?

Provided the fence voltage does not exceed 600 volts and an earth point is available for the black probe to contact' then this may be used for the measurement. Obviously any source over 100 volts requires care so as not to allow live conductors to contact bare skin.
