LIBRARY VIS
The Model 30 LabVIEW library contains all the VIs that control and collect data from the instrument. Each of the library’s VIs are documented below. Each of
the VIs has VISA handles or error clusters as inputs and outputs, and more information on these elements can be found in the LabVIEW documentation. Inputs
or outputs specific to this library are documented below.
In addition, there are two VIs that are not considered part of the library, but are provided as example VIs that uses the library. These VIs are documented in the
Sample VIs section below.
The VIs
M30 Test & Parse Data.vi, M30 Parse & Assign Data.vi, and M30 Parse 31-Byte Block.vi are internal functions used by M30 Collect Data.vi, and are not
documented here. However, their block diagrams are included if you wish to browse through them.

M30 CLUSTER
The M30 Cluster has the following elements:
Value
Format
Description
P1
Double
P1 pressure value as displayed on the front panel
P1 ADC
32-bit signed integer
The raw P1 pressure value from the analog-to-digital converter
P1 Tare
32-bit signed integer
The value subtracted (tared) from the P1 ADC value prior to a conversion to pressure.
P1 Temp
32-bit signed integer
The raw P1 temperature value from the analog-to-digital converter
P1 Range
16-bit signed integer
The selected range (units) of the P1 sensor
P2
Double
P2 pressure value as displayed on the front panel
P2 ADC
32-bit signed integer
The raw P2 pressure value from the analog-to-digital converter
P2 Tare
32-bit signed integer
The value subtracted (tared) from the P2 ADC value prior to a conversion to pressure.
P2 Temp
32-bit signed integer
