1 Introduction Interface Adapter Whereas interface adapter BD232 allows for online transmission of measured values from multimeter to PC, memory adapter SI232/-II is additionally capable of saving multimeter data on-site without a PC. The values thus stored to memory can subsequently be transmitted to a PC. PC-Analysis Software METRAwin 10 is a high-performance analysis software for use with WINDOWS. It allows for user-friendly recording, storing, display and documentation of measurement dat

3 Multimeter, Adapter and METRAwin 10 Operating Modes 3.1 General Information The address for the adapter and its corresponding multimeter must be identical. The baud rates for the adapter and the multimeter must also be the same. The multimeter’s sampling rate should be faster than the speed at which data are requested by the memory adapter or METRAwin 10 software. 3.2 Saving Measurement Data to Memory in the Multimeter – for METRAHit 22M, 26M and 29S only METRAHit, 22M, 26M or 29S onl

The special interval -:--.-- is used to save only one measurement value after the STORE mode has been started. The next time the STORE mode is started, a single measurement value is stored once again. In this way, measurement values from 2x multimet

7.3 Trigger Settings – triG The trigger setting determines which multimeter measurement values will be stored to the adapter. Beyond this, storage to memory can be started by means of various trigger types (st-ou, st-in, out, in). A trigger event occurs when high level is exceeded, or if low level is fallen short of. Recording may take place before or after the trigger event. Recording duration depends upon the sampling rate, the hysteresis setting, available mem- ory capacity and the desire
