01: Do (P86)

1: 41 Set Port 1 High ;Jumper wire from SW12V control to C1

;Orange wire (C1) if older wiring

;Green wire (C1) if using SW12V device

;For CR23X or CR5000 use 49 for SW12V internal

;control port

;Pause 150 mSec before making measurements so the

;probe can stabilize on true readings.
