The Siemens B1105 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 an OEM version of the Gossen Metrawatt Metrahit 28S. The only differences seem to be the type, logo and color (light grey-blue print on knob, light grey-blue holster) and the voltage rating.

| 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 | 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. |
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.
