The Gossen Metrawatt Metrahit 14S is a 3100 counts handheld digital multimeter with IR (RS232) connectivity.
It is expected to work with the driver gmc-mh-1x-2x-rs232, but unsupported due to lack of a test device.
This page is a work in progress, information incomplete and possibly inaccurate!

To enable the ranges 300.0 µA, 3.000 mA and 3.000 A DC, switch function selector to circle with dot symbol and press yellow button. Wait until auto calibration of these ranges is finished ("CAL" in display disappears). After that the ranges are available in the mA resp. A function until multimeter powered off automatically or manually.
The column "sigrok result" contains in short form what the driver generates for the resp. data type.
