12v Voltmeter with audible alarm for low voltage, perfect for monitoring the voltage/charging system of your car, boat, caravan, motorbike, RC model or various other applications (e.g. electric fence batteries, 12v lighting systems, solar charging system etc.).
Now all our 6 LED monitor models come ready programmed with 6 different voltage 'curves'. It's easy to select the curve you want, and once set, it stays set even if the unit is disconnected. You select the curve you want using the button on the front panel in an easy set up sequence - full instructions are enclosed.
The 6 curves are all slightly different, and this allows you to tune the monitor to your particular application. The idea is that once you've found the curve that relates best to your battery and how you use it, you don't need to worry about the numbers, just the colours - this makes using the monitor very intuitive. The six standard curves are shown below, and you can customise all six of them if you wish. To do this, copy and paste the table of voltages, edit it to your requirements, and email it to me (contact details at the footer).
The Audible Alarm starts to bleep when the voltage drops below a particular threshold (see table below - and remember all values may be custom set for you). The longer the period the alarm sounds, the longer the silence between bleeps - so you know you've hit low voltage, but you don't want to hit the monitor! You can silence the alarm completely by putting the monitor into sleep mode, and turning it back on once you've charged or are charging your battery.
There are 12 distinct output states as detailled below (standard 12v thresholds shown - 24v will normally be double these values), offering fine measurement of your battery's voltage. Monitors now come programmed with six different voltage "curves", allowing you to fine tune the monitor to your application. If you wish any or all of the curves custom programmed, let us know the values you need and we will do it. There will be no extra cost, and no delay in dispatch. Please consider if the Alarm Threshold values are right for your application, keeping in mind that a heavy load on a battery will bring down the measured voltage.
could not be easier - the module has just two wires to connect - red to
+12v/positive battery terminal, and black to
negative battery terminal or ground - you can connect it straight to the battery, or
elsewhere in the circuit of your application. There are only two wires
to connect - the module comes with 500mm flying leads. Instructions
are provided and help is always available.
