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 The raw P2 temperature value from the analog-to-digital converter

P2 Range 16-bit signed integer The selected range (units) of the P2 sensor

mA Double mA value as displayed on the front panel

mA ADC 32-bit signed integer The raw mA value from the analog-to-digital converter

Battery 16-bit signed integer Three values: -1 = dead, 0 = low, 1 = good
