I have a eevblog brymen meter that I purchased appx. 2-3 years ago. When i turn the meter on from the off position to the first position which is for voltage, the meter works. If I move the selector switch past that position to any other position, the display is blank. I replaced the batteries twice but I dont know why it doesnt work. Can someone tell me what to do? I hardly used the meter and it stopped working. Thanks.
