Expanded scale voltmeter question
Hello guys...
I just want opinions about this. I bought an [link=http://www.hobbico.com/fieldequip/hcap0351.html]Hobbico Expanded scale voltmeter MkII[/link]. On their web site...they state "Simulates a very realistic 225-275mAh load for testing batteries..."
I just checked mine and it draw only 180ma on the receiver side (4.8v). I am an eletronic technician so i did some calculations and replaced the 21 ohms resistor with a 15 ohms to get a 250ma load. Now i realized that the resistor i replaced also affected the TX (9.6v) side so i put back the original 21 ohms resistor. Did anyone else ever mesure his voltmeter load ? Should i buy another one or it's not a big deal ? I lost a plane due to a batterie failure so now i am very peeky with my packs. Thx for you advices everybody. [X(]
