subject: Some Safety Guides When Using A Digital Multimeter [print this page] When you want to test electronic units such as voltage, ohms and others, the multimeters are required. There are two types of multimeters: analog multimeters and digital multimeters. Nowadays, digital multimeters are replacing the analog types due to their convenience and functionality. The advantages of owning digital multimeters are that they are convenient, handy and precise. Futhermore, you need not worry about not being able to read the measurements accurately. Digital multimeters display readings in digits thus you get precise values down to the last decimal point.
While just like any other electronic device, digital multimeters can also cause hazards especially when mishandled. Such risks as electric shock or other types of injuries, therefore it is crucial for people who usually do measures to know the safety tips when using a digital multimeter.
Firstly, you need to do is to wear a pair of insulated gloves while operating with a digital multimeter. Although the voltage that you usually need to test out may be small, it can still cause discomfort if you get yourself mildly electrocuted in the process. Check the test leads for any damages. If you see some damage, then do not use the meter and risk yourself from getting electrocuted. Do not touch the probes to the voltage source if the lead is plugged directly to a 10A input jack.
Secondly, make sure that the circuit that you are going to measure does not go beyond 4800 watts; otherwise this will also cause you slight shock. When working with voltages that are above 60 V DC, then you need to be extra careful since these voltages can cause the risk of shock hazards. However, in instances when you need to work with such voltages, make sure that you double your protection and wear high-quality insulated gloves.
On the other hand, make sure that all of your fingers are behind the finger guards that are placed to separate the test probe from the meter when taking your measurements. The finger guard is made with insulated material to protect against electrical shock.
Lastly, test your battery all the time. Most digital multimeters come with a battery indicator thus if the battery is near empty, make sure to replace it. Replacing the battery does not only save you from getting false readings but it also prevents fluctuation of energy in the unit which can cause electric shocks.
Digital multimeters will serve you through the years with proper care, regular maintenance and calibration.
