The easy-to-read digital display shows the battery's condition in easy to read digital voltage display as well as bar graph for battery charge level. The danger arises when substandard equiepment or wiring is used or if the proper safety precautions are not employed.Īs always if you have any doubts, always consult a proffesional electrician. 12V LCD lets you see your battery voltage. I don't wish to be sacre monger so rest assured that a properly installed wiring system should not cause any problems, whetehr its 230Vac or 12V dc.
Well a 12V lead acid battery can deliver much more current than a 230Vac socket, and given the heating power of such current the danger of fire is probably greater than in the domestic 230V systems.īecause the meter only requires such a relatively low current, the wires they supply will have a small crossectional area and they require even less of an overload to cause them to self-heat under fault conditions. There is a misconception that when working with 12v systems, because there is virtually no danger of elecric shock from a 12V potential difference that its dosent need to be treated with as much care. Was the Titanic was unsinkable? Your wiring despite your best efforts might still be damaged, if not by you perhaps by someone who has the caravan after you. Some digital automotive meters may use current from the measureand (like the analog meter) to power the display.įor simply monitoring battery voltage, a pair of wires from the battery to anywhere in the caravan that ONLY feed the volt meter should be fine, as there is virtually no current being used so voltage drop will not be a problem.Ĭlick to expand. Avoid moving iron meters which are relatively inaccurate and the will use a modest currentĪn analog moving coil meter with a current limiting resister will use a very small current from the potential difference being monitored to activate the needle, But a digital meter may need to have a seperate battery to power the measurment electromics. The multimeter draws very little current to measure battery voltage and has a negligible effect on the charging process. If the intention is to have a permamant display, then you need to consider how the meters work. The AVO analog meters are fine devices, but even these need recalibrating from time to time to be certain of their accuracy. However for the purpose of monitoring battery condition, a meter that can resolve to 0.1V should be more than adequate. In reality unless a meter is calibrated and the sytems error is known you cannot trust any meter digital or analog.
