Name

FLDMMtask - Fluke 8846a I/O service

Synopsis

FLDMMtask <argument list>

Description

Network I/O service for a Fluke 8846a 6.5 digit precision multimeter.

The program expects to find several refnames under the label. See Fluke Multimeter Database RefNames for more information.

Arguments

Argument processing is done using Unix long argument syntax.

The values of all the parameters listed here are printed on stderr when the program starts, whether or not they were supplied on the command line.

--dbman_host <hn>
The host where dbman is running. This is optional, and will default to localhost or the current value of the DBMAN_HOST environment variable.
--fluke_host <hn>
The hostname of the multimeter. This can also be an IP address. The default value is localhost.
--fluke_port <n>
The port to connect to on the multimeter. The default value for this is 3490.
--mngr_conf <file>
The pathname to the MNGRconf file to use. This value defaults to MNGRconf in the current directory.
--mngr_pn <pn>
The program name to use when parsing the --mngr_conf file. This value defaults to FLDMMtask.
--help

Prints a help message detailing program usage and the current Accelnet version.

Fluke Multimeter Database RefNames

The RefNames in this group relate to parameters in the Fluke Multimeter.

Vr

This is the generic readback of the meter. Unless the mode is changed, is in Volts DC.

ResetSC

This is a momentary, that resets the meter to somewhat sane values. It performs a device reset, turns the beeper off and sets the measurement up.

ModeSC

All 13 available modes of the meter are currently supported. Take care that the meter is not connected while switching modes.

ModeSR

This reports the current measurement mode that the multimeter is in.

RangeSR

This reports the current measurement range of the insturment. The ranges available varry between the different measurement modes.

StatusSR

This contains any errors encountered by the meter. These are usually communication errors, and are cleared after each read.

Misc

This program places the instrument in autoranging mode. This causes the instrument to occasionally report overload or underload if nothing is connected, or if the probes are improperly connected. Currently this overload or underload condition may cause the job to reset it’s connection to the meter as the READ? command may attempt to wait for a good value before returning.

MNGRconf Example

This shows what an expected MNGRconf file will be. The VR & RangeSR should generally be E6 in the database.

Examples

FLDMMtask.tcl --fluke_host flukedmm

This starts FLDMMtask with mngrconf in the current directory, and connects to the multimeter at port 3490.
