B.1.2. Edlog Single-Ended Measurement Program
Below is an example CR10X program. Information about using it with other
Edlog dataloggers are provided in the program’s comments.
;Turn the HMP155A on.
;
01: Do (P86)
1: 41
Set Port 1 High ;Jumper wire from SW12V control to C1
;Green wire (C1) if using SW12V Power Switch
;For CR23X or CR5000 use 49 for SW12V internal
;control port
;Pause 2 seconds before making measurements so the
;probe can stabilize on true readings.
;
02: Excitation with Delay (P22)
1: 1
