Hello.

I want to buy multimeter but I don't found some terms of it's data sheet.

there are:

Live wire judging - checking of wire continuity?
Continuity buzzer - Continuity checker?
Restorable Fuse protection - automatic fuse?

Thank you in advance.

 

These are my guesses to the terms:

Live wire judging - shows when a wire or outlet has power line AC

Continuity buzzer - an audible tone when the resistance is below a certain value

Restorable Fuse protection - a resettable fuse that protects the meter from current overload

 

Thank you.
Could you say me what does means integral number +10 after 0.8% in brackets? This data from some multimeter data sheet
AC Voltage
400mV/4V/40V/400V/750V
accuracy ±(0.8%+10)

 

Translating from bad English requires context. Is the complete meter data sheet available online? Can you give a link or brand and model information?

Accuracy ratings. Meaning if it said 400mv +10 usually means that values can be from 390-410. or .8% accuracy. Tells how detailed the measurment is.

 

That sheet is quite badly written. Those added values make no sense to me. They kind of look like dB values but still make no sense unless they're a crude high-side offset to the percentage figure.

For example 10MHz ±(1.0%+10) would yield the following for a 1MHz signal: 990kHz - 1.01001MHz.
