Digital Zeus™ HVAC Tool & Instruments Journal

 First off, for anyone that does not already know, I have never touched a digital refrigeration service analyzer of any kind in my life.

Having said that, my first observation was how well protected the 523 was in its heavy, well padded case.
Nice for shipping or long term storage.
Not very practical for day to day use IMO.
Sorry, I just do not have the patience to pack and unpack this thing for every job, but thats just me I guess.

My first lesson learned during my evaluation period, and one I will not forget is………….read the operating instructions BEFORE attempting to use this or any similar device.

Here you can see how clean the display is.

This one shows the backlit display from approx 4 foot away.
