The Gossen Metrawatt Metrahit 14A is a 3100 counts handheld digital multimeter with IR (RS232) connectivity.

It is very similar to the Metrahit 14S, but has no ranges of 3 µA= and 3 mA≈.

Data Hold				mqflags += HOLD	Disabled while IR interface is active.
MIN				mqflags += MIN	Influences only display, via IR flag is set, but actual current value is delivered.
MAX				mqflags += MAX	Influences only display, via IR flag is set, but actual current value is delivered.

The column "sigrok result" contains in short form what the driver generates for the resp. data type.
