Operating Modes

With the channels configured and operating conditions set, the instrument is ready for operation in one of the following modes:

∙Using the Scan Mode (Figure 2-15)

∙Using the Monitor Mode (Figure 2-17)

∙Using the Review Mode (Figure 2-18)

Each operating mode is discussed below. To modify the operating mode with additional features, such as using the scan triggering, refer to the next main headings in this chapter, "Additional Features."

Using the Scan Mode

Perform the procedure in Figure 2-15 to start and stop the Scan Mode of operation. The Scan Mode can be started when the instrument is inactive, in Monitor (Figure 2-17), or Review (Figure 2-18). Measurement results can be sent to a memory card (see Chapter 3, "Memory Card Operations") and PC (see Chapter 4, "Computer Operations") or printer (see Chapter 5, "Printer Operations"). When using the Scan Mode with a memory card, consider each of the following topics. (Memory card error messages are summarized in Figure 2-16.)

Memory Card as a Data Destination

Measurement data is not automatically sent to the memory card. Measurement data can be sent to a printer/PC, to the memory card, to both printer/PC and memory card, or to neither. If either the printer/PC or memory card, or both are selected, the PRN annunciator will be on. See Figure 3-4 to set the destination and mode for sending measurement data to the memory card.

Memory Card Formatting

When the instrument is inactive (not scanning or monitoring), insert a memory card. An immediate error Err 1/CArd indicates the memory card is not initialized (formatted). See Figure 3-3 to initialize a memory card.

Memory Card Capacity

A memory card that fills during scanning displays the error Err 3/FULL, meaning readings are being saved in internal memory (75 scans maximum) and another card should be inserted. The error changes to Err 4/FULL if the internal memory fills, saving only the most recent 75 scans. When inserted, the replacement card is updated with the scans in memory.

Memory Card Files

Data files (dAtxx) are opened manually (see Figure 3-8) or prompted by pressing Q. Press Eto accept file names or use the up/down and left/right arrow keys to select a file name and then press E. If a data file cannot be opened, error Err 2/FILE will be displayed, meaning all files dAt00 to dAt99 already exist or the selected file name is already assigned.

Memory Card Exchange During Scanning

Eject the active card when the BUSY indicator is off and replace with another card. The instrument opens the same file name on the new card. If this file cannot be opened, Err
