Figure 1-1. Data Bucket Front and Rear Panels
Front Panel Operation
Front panel operations include configuration of channels in preparation for scanning
operations and simple multimeter operation by placing the instrument in the Monitor
mode then using the front panel jacks and test leads (channel 0) for measurements. Front
panel operations are discussed in Chapter 2.
Memory Card Operation
An adjunct to stand-alone front panel use are operations that use the memory card
feature. The memory card is a Static Random Access Memory (SRAM) device that plugs
into a slot on the Data Bucket front panel. An internal battery maintains the integrity of
the stored data. An empty 256K-byte card stores 8500 scans of 4 channels, 4500 scans of
10 channels, or 2500 scans of 20 channels. A typical display while scanning using the
memory card is shown in Figure 1-2. The PC-compatible memory card can be used to
store measurement files and configuration files. Data extraction from the card requires a
