Software used for controlling and data logging lab equipment.
function currentPress = gilsonpumpobjcurrentpress(gilsonPumpObj)
% GILSONPUMPOBJCURRENTPRESS returns the current pressure of Gilson pumps
% currentPress = gilsonpumpobjcurrentpress(pumpObj) returns the current
% pressure of Gilson 30x pumps connected to a valid serial port object, as
% numbers (precision: double). Although the GUI has been designed to
% mitigate this, the response is 'N' if there is no Gilson 80x manometric
% module installed. The response to the command is either 'N' or 'Bxxx'
% where xxx is the pressure in bars.
% checks the number of arguments
error(nargchk(1, 1, nargin))
deviceID = 1;
% sends command
currentPress = gilsonpumpobjcomm('read', gilsonPumpObj, deviceID, 'Q');
% extracts out the numeric part of the string, then converts it into a
% proper number - this will return a NaN if it was not successful (the pump
% will respond with an N if there is no manometric module installed)
currentPress = str2double(currentPress(isstrprop(currentPress, 'digit')));
% if it was a NaN, error
error('Manometric module is not installed or is not functioning correctly.')
