What should you not do with a multimeter?

Safety Tips to Measuring Voltage With a MultimeterDo not use your test leads if the protective insulation on the leads or probes is cracked or worn. … The movement of current from one hand to the other during an electric shock is the most dangerous. … Both DC and AC voltage can be very dangerous.

What is the principle of multimeter?

A multimeter, shown in Figure 1, is a device used to measure two or more electrical quantities. A multimeter can be used to measure electrical functions such as voltage, current, resistance, continuity and some are able to measure electrical frequency.

What does 6000 counts mean on a multimeter?

Counts: A digital multimeter resolution is also specified in counts. Higher counts provide better resolution for certain measurements. … Fluke offers 3½-digit digital multimeters with counts of up to 6000 (meaning a max of 5999 on the meter’s display) and 4½-digit meters with counts of either 20000 or 50000.

What is a 4000 count multimeter?

Meaning, an instrument with this digit resolution would have 4000 counts. … For example, if the range of the multimeter for dc voltage is 2 V, 20 V, 200 V, 1000 V, it can be assumed that most likely the meter has a 1/2 digit.

Is a house AC or DC?

Many devices in your house need DC. When you plug things into the outlet in your house, you don’t get DC. Household outlets are AC – Alternating Current. This current has a frequency of 60 Hz and would look something like this (if you plotted current as a function of time).

What is the symbol for current?

The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). Current intensity is often referred to simply as current. The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating Ampère’s force law (1820).
