6.11 Multimeter Functions

Modules for the following digital multimeters exist:

kontron4060

Kontron 4060

schlum7150

Schlumberger 7150

To use a module in an experiment put its name into the DEVICES section of the EDL script.

List of multimeter functions:

`multimeter_name()'

`multimeter_mode()'

`multimeter_precision()'

`multimeter_get_data()'

`multimeter_ac_measurement()'

`multimeter_dc_measurement()'

`multimeter_lock_keyboard()'

Descriptions of multimeter functions:

`multimeter_name()'

Returns a string with the name of the multimeter being used.

`multimeter_mode()'

If called with no argument the function returns the currently set measurement mode (as an integer), if called with an argument the mode gets set. For the Kontron 4060 voltmeter the possible arguments are either the string "Vdc" (or the integer number 0) to switch to DC voltage mode or the string "Vac" (or the integer 1) to switch to AC voltage mode. For the Schlumberger 7150 additional possible arguments are the strings "Idc" (or the integer 2) for DC current mode and "Iac" (or the integer 3) for AC current mode.

`multimeter_precision()'

This function exists only for the Schlumberger 7150. It allows to determine or set the precision measurements are done with. If called with no argument, the current precision setting gets returned as an integer. If called with an argument the precision gets set. Allowed arguments are the string "3.5" (or the integer number 0) to set the device to a precision of 3.5 digits, "4.5" (or the integer 1) for 4.5 digits, "5.5" (or 2) for 5.5 digits or "6.5" (or 3) for 6.5 digits.

`multimeter_get_data()'

The function returns the voltage or current (depending on the mode) measured by the multimeter.

`multimeter_ac_measurement()'

This function is only available for the Kontron 4060 and switches it to doing AC measurements. The function is deprecated and should be replaced by a call of multimeter_mode().

`multimeter_dc_measurement()'

This function is only available for the Kontron 4060 and switches it to doing DC measurements. The function is deprecated and should be replaced by a call of multimeter_mode().

`multimeter_lock_keyboard()'

This function is only available for the Schlumberger 7150. Usually during an experiment the keyboard of the device is locked. But for situations where it would be useful to be able to control the device also via its keyboard it can be unlocked (and also re-locked) from within the script. To unlock the keyboard call this function with an argument of 0 or "OFF", to re-lock the keyboard call it again with a non-zero argument, "ON" or no argument at all.

The function can only be used in the EXPERIMENT section of an EDL script.
