This is a VI-Template for LabMax PC Application Frontpanel instances.
The Main-Panel will be created from the CH_LM App Main.vi. More Child-Panels can be created from the menu of the Main- or Child-Panels. Child-Panels can be closed, but the application can be exited from the Main-Panel only.

Update Status Click here to update the status of the selected LabMax, especially the Measurement Range of a new sensor. Note: The meter will be locked for remote operation again. |
|
LabMax Meters Ring is populated with the serial numbers of all selected LabMax meters, with the currently visible serial number indicating the selected LabMax meter. Note: Ongoing data logging is stopped and all history buffers are cleared when another device is selected, connected to or disconnected from USB. |

Sample Size Selects the sample size to collect when in Fixed mode, and the sample size to use for statistics when in both Fixed and Continuous mode. |
|
Collection Mode Select between continuous data acquisition and data acquisition on a fixed time interval. |
|
Time Interval |
|
Streaming |
|
T / ms Sets the collection interval when in time interval data collection mode. This control should only be visible when time interval data collection is selected and hidden when continuous is selected. |
|
NofBins intervals must be greater than zero. If intervals is less than or equal to zero, the histogram is undefined, and the VI sets Histogram: h(X) and X Values to empty arrays and returns an error. The default is 1. |
|
Point(s) Enables averaging of the last N data points for the Power/Energy and plot displays. |

|
Tuning Scale Use this button to select the scaling range of the tuning meter. Min - Max: sets the low end of the scale range to the Minimum value in the current data set and the high end of the scale range to the highest value measured since the last reset. Zero - Max: sets the scale range from Zero to the Maximum of the granted measurement range. |

Sample Size Selects the sample size to collect when in Fixed mode, and the sample size to use for statistics when in both Fixed and Continuous mode. |
|
Reset Resets the data set used for statistics (Mean, Min, Max, Std Dev, and Counts). |
|
Measurement Range Select between auto ranging and fixed manual ranges. This control needs to be set to the current state of the meter when switching between or initializing meters, and populated with choices based on the current probe attached and the measurement mode. |
|
Collection Interval Sets the collection interval when in time interval data collection mode. This control should only be visible when time interval data collection is selected and hidden when continuous is selected. |
|
Zero Meter Zeroes the FieldMaxII meter. |
|
Wavelength Wavelength of operation to set. Unit: nm Range: 1 - 99999 nm Default: 1064 nm Note: You can edit the unit string, especially the prefix( n/u) to your needs The attached probe limits the wavelength of operation to the range of minimum and maximum wavelengths stored in the attached probe. If requested wavelength is less than the minimum wavelength, the granted wavelength is set to the minimum wavelength. If requested wavelength is greater than the maximum wavelength, the granted wavelength is set to the maximum wavelength. If a valid probe is not attached, the minimum wavelength is taken as 1 nm and the maximum wavelength is taken as 99999 nm. |
|
Wavelength Units Selects the length unit of Wavelength to um: micrometer nm: nanometer |
|
Collection Interval Units Sets the time unit of Collection Interval to sec: seconds min: minutes hr: hours |
|
% Sets the internal trigger threshold in % of full-scale. |
|
Factor Factor used in attenuation correction. Default Value: 1.0 Range: 0.01 - 999.99 |
|
Attenuation Correction Turns the attenuation correction feature on and off. |
|
% Of Mean Display the Standard Deviation relativ to Mean value. Range: True: % of Mean value False: Ablsolute value of Standard Deviation Default: False |

LabMax Device List Element This cluster correlates a serial number and the corresponding connection index of a LabMax device. |
|
Serial Number Specifies the serial number of the instrument to use. Hint: Serial number can be ignored if in case of GPIB or RS232 communication mode. |
|
Meter Index The meter index parameter that exists in many places in the API will have different meanings for the different communication modes: USB: a number from 0 to 127, used as an OS assigned number to meters that are connected to and disconnected from the computer via the USB GPIB: a number from 0 to 31, used as the user assigned GPIB address RS232: a number from 1 to 9, used as the user assigned COM port number (for example, 2 represents COM2) |
