MULTIMETER SAFETY PRECAUTIONS

Post by Admin on Thu Aug 13, 2015 3:11 pm

THIS IS AN IMPORTANT THINGS THAT WE SHOULD OBSERVE AS WE USE MULTITESTER:

1. The multimeter should only be used by personnel qualified to recognize shock hazards and 
trained in the safety precautions required to avoid possible injury. 

2. Do not work alone when making measurements of circuits where a shock hazard might 
exist. Notify a nearby person that you are making, or intend on making such measurements. 

3. Locate all voltage sources and accessible current paths before making measurement 
connections. Be sure the equipment is properly grounded and the right rating and type of 
fuse(s) is installed. Set the instrument to the proper range before applying power. 

4. For power supply circuits, turn off power and discharge all capacitors before connecting or 
disconnecting test leads to and from the circuit being measured.

Sir, multitester should not be reached by children and it is not a toy to play with. it is an instrument that we use as we deal with electricity. Thanks for this information, all user should know and keep in mind all this things. Godbless.

For example Sir, we do not follow the safety precautions in using a multimeter and we experienced electric shock, will it lead us to death?

Is there any multi-tester that automatically adjust itself to ohmmeter,voltmeter and ammeter?

the probes must properly coated or insulated we must not allow the presence of copper to be seen or touched by our bare hands to avoid shock

Analog multitester and digital multitester are both using swith to sellect what measurement you want to use. it doesn't automatically adjust itself.. Smile Smile

METER SAFETY PRECAUTIONSAs with other meters, the incorrect use of a multimeter could cause injury or damage. The followingsafety precautions are the MINIMUM for using a multimeter. Deenergize and discharge the circuit completely before connecting or disconnecting amultimeter. Never apply power to the circuit while measuring resistance with a multimeter. Connect the multimeter in series with the circuit for current measurements, and in parallel forvoltage measurements. Be certain the multimeter is switched to ac before attempting to measure ac circuits. Observe proper dc polarity when measuring dc. When you are finished with a multimeter, switch it to the OFF position, if available. If there isno OFF position, switch the multimeter to the highest ac voltage position. Always start with the highest voltage or current range. Select a final range that allows a reading near the middle of the scale. Adjust the "0 ohms" reading after changing resistance ranges and before making a resistancemeasurement. Be certain to read ac measurements on the ac scale of a multimeter. Observe the general safety precautions for electrical and electronic devices.

Alam naman po natin ang mga advantages ng pag gamit ng Digital multi-tester
pero mayron parin bang mga Dis-Advantages ito? Ano-ano po ito

at minsan po ba may tyansa po ba na mag kamali ng Pag bibigay ng resulta ang Digital Multi-tester???

not necessary that you need to use digital, unnecessary incidents may lead to accident if we does not follow the proper procedures

Do not touch any object that could provide a current path to the common side of the circuit
under test or power line ground. Always stand on a dry insulating surface capable of
withstanding the voltage being measured, or that could be encountered.
