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.
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.

4 Adapter Connection and Initial Start-Up 4.1 Connecting the Adapter The screw connections between the stacked adapters serve exclusively to secure the connections at the serial interface plug connectors. Disconnect each individual adapter prior to transport in order to prevent them from being damaged. ➭ Connect the 9-pin subminiature socket at the connector cable to a vacant COM port at the PC. ➭ Plug the other end of the cable into the left side of the first adapter.
➭ After selecting the “File/Measure” menu item, the recorded measurement values are transmitted to the PC and are displayed at the monitor in accordance with the display mode selected in the “Set” menu. 4.3 Initial Start-Up – BD232 Interface Adapter ➭ Set the multimeter to the data transmission mode before performing measurement by simultaneously pressing the DATA key and the ON key. ➭ Start the PC and METRAwin 10 software.

5.2 Display 3 1 2 Figure 4.3 1 2 3 Memory Adapter LCD Digital Display The current menu item appears at the 7 segment liquid crystal display during manual operation of the memory adapter. When stored data are viewed, measurement values appear at the display in digital format (menu item “reCAll”, chapter •, page 21). Analog Display Available memory space can be estimated with the help of the analog display. For example, the diagram in chapter 5.
5.3 Switching the Memory Adapter ON and OFF Briefly press the right-hand ON/OFF key in order to switch the memory adapter ON. The analog scale appears at the LCD along with a display of remaining memory capacity, above which the last selected operating status is displayed at the left-hand side. The memory adapter is ready for operation. Figure 4.4 Initial Display Press the yellow ESC key until the initial display appears in order to switch the memory adapter OFF (see above).
6 Operating Instructions at a Glance The memory adapter can be operated with the keypad on the device, or more conveniently with METRAwin 10 software. The most important functions from the operating menu can also be selected with hot-keys (shortcut function). 6.1 Menu Driven Operation • The key acknowledges a menu item and opens the respective operating menu level. The same key with the symbol moves the cursor to the right, for example when entering the time.
6.3 Shortcuts at the Multimeter • Select Normal Operation – – – – Switch the device off, and then back on. Or, if the device is in the measuring mode: press the FUNC and ON keys simultaneously. Or, if a selection menu is open: select STORE - STOP and acknowledge with ON. Or, if the device is in the SEND mode: select SEND - OFF in the SET menu. • Transmit Measurement Data to the Adapter – SEND Mode – Switch the multimeter on by simultaneously pressing DATA and ON. – Or, select SEND in the SET menu.

7 Menu Item Descriptions 7.1 Set Sampling Rate – rAtE Key Sequence: SEt rAtE m:ss.hh Settings: m = minutes, ss = seconds, hh = hundredths of a second The sampling rate determines the time resolution of the data recorded to the memory adapter. 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.
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.
