The Gossen Metrawatt Metrahit 29S is a 310000 counts 1000V CAT III/600 V CAT IV (older version) or 600V CAT III/300 V CAT IV (newer version) handheld digital multimeter with IR (RS232/USB) connectivity.
It is similiar to the Metrahit 28S, but has additional energy measurement and data logging capabilities. While the functions common with the Metrahit 28S are expected to work, the additional features are not implemented yet.
Hardware

| Event count | mq V, unit V, mqflags AC,RMS,REL | Counts events >= 2500 digits that last >=2s with a break >=2s. To activate, switch to voltage ACDC, press yellow button twice. Press up to 4 times to cycle parameters, press long to stop. See manual. Not useful remotely because the current measurement value is sent, not the counter. | |||
| Stop Watch | 100 ns | (Time data) | Max. 100 Min. To activate, select a 3V-1000V≃ range manually, press yellow button, press AUTO for start/stop, DATA for reset. Using the stop watch delivers only voltage data and sometimes seems to bring the device into a mode where it even sends invalid data packets. | ||
| Data Hold | mqflags += HOLD | Disabled while IR interface is active on Matthias' test device. | |||
| 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. |
Energy measurement functions missing yet.
The Accuracy row was simplified, see manual for exact specs. If the value contains three values, the middle value is % or range.
The column "sigrok result" contains in short form what the driver generates for the resp. data type.
