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 | (Time data) | To activate, select a 3V-1000V range manually, press yellow button, press AUTO for start/stop, DATA for reset. Delivers only invalid data ("Overflow") via IR on Matthias' test device. | |||
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. |
The column "sigrok result" contains in short form what the driver generates for the resp. data type.
