content: Quote from: roket on February 25, 2014, 05:53:19 amWHAT is the brightness currently set to?Robrenz is explaining that you can adjust the brightness through the front panel, he's not asking you to open up and adjust anything. Of course if it is already set to HIGH, then it's already as bright as it can go (assuming no hardware problems).cheers,george.

content: it is natural, I adjusted everything on a maximum. problem in the display. to the device 7 years. everything works perfectly except the display. I think that a display old age. I on the fluke 125 too put light-emitting diodes instead of lamp CCFL. there everything is simple. here other display. I think that can return the device to the seller. I bought for 1060 dollars with delivery to Moscow from Israel. the device very much was pleasant though I already had other branded multimeters. the last calibration in 2007 and it still in the range

content: Thank you Erik, I have just set our 8845A here to Medium. Yes, the packing is unusual. Perhaps they should wrap the unit in a soft cloth bag, and then place it in those plastic carriers in the carton.
