Oil pressure readings / indications

[jordan rubin <nuttenschleuder@xxxx>]

Hello all:

According to the tech bible

Oil pressure, warm engine, new oil/filter

900 rpm min. 14.2 psi
3000 rpm 57.0 psi

The pictures on the howto show something drasticaly
different. So where looking at one or more of three
things.

1. Oil sending unit (new) not calibrated for gauge
2. Gauge out of calibration
3. Calibrated but oil pressure is excessive.

Standard oil gauges readings are relative to changes
in the cables resistance between ground. So if I
ground the sire to the gauge, it drops to zero, take
it off it flys to the top.

The question is... 

Does anyone know what the resistance value is in
ohms at the different intervals on the gauge. I
believe the gauge is in incriments on 20psi.

if (X)ohms takes the gauge to 40psi and (2X)ohms to
80, i can see not only if my gauge is correct, but the
sending unit too.

thanx
