[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I have an M4P and a friend who just sold me (for a very good price, I could not refuse) an MR meter; not an "MR4", which I understand to be the same but in black. My questions are: 1. What does the plastic moveable arm on the front next to the 90 degree window do? If it is a battery check, I have a working battery but I'm getting nothing from moving the arm. 2. What are my choices to power this when the cell that is current runs out? Do some states allow mercury batteries, how much to convert this meter to lithium.... and so on? DF
