Do I have to do anything special with them before use?
Just slap on the hoses and battery and get to work? That simple?
Yes, the only prerequisite to using them is......"beat the crap out of them" You cant hurt them even if trying....no need to calibrate anything, just use them and enjoy having the toughest and best available.
Just today I had one set of mine soaked in POE when I made a mistake not closing a valve after changing an oil safety on a low temp rack. The other set was in a -2 supermarket walk in freezer to find a flooding evap, after finishing and taking it out of the freezer, it was soaked in condensate. But all is well as both did this many times in the past with no harm. There just isn't any better, there just isn't any other.
PS: one was an AK900 the other was a DRSA1250

Reason: I wanted to identify what drsa m#'s I used today. 1250 oil soaked AK900 water soaked.
Great!...an expensive tool thats going to break as soon as the warranty runs out.
My DRSA 1200/1250 is from the Spring of 2007 also... I can say without a doubt this is the TOUGHEST electronic tool I own.
I ordered an AK900 (bought it direct from Doug/Brenda, because I did not want the 3 hose manifold... I use a 4 valver). Nice to have a back-up unit during busy season. For 6 years I did not have back-up, depended on the DC and it worked well. And yes, they WILL take the abuse folks talk about.
If anyone knows how tuff 'Snap-On' tools are for vehicle repair... well DC is the snap-on of digital gauge sets.
Cool, they are even better than your bar-maids... <grin>
I dont own a set of digital gauges because I hear so many complaints on here and at wholesale houses. Maybe this brand is a really good one?...I dunno. How many brands are there now? Who makes the best? Who has the best warranty and support? best bang for the buck?
