Lines following the time and date contain measurement data for channels that have been set up for this session. The last line of the printout contains the Totalizer count and the status of the digital I/O lines.

Channel data is formatted to fit three readings onto an 80-column line. Each reading provides the following information:

∙Channel number, followed by a colon and a space (4 characters)

∙space or minus sign (1 character)

∙Digits and decimal point. Measurements taken at the fast rate use 5 characters (4 digits plus a decimal point.) Measurements taken at the slow rate use 6 characters (5 digits plus a decimal point.)

∙Space(1 character)

∙Measurement multiplier - ’m for X0.001, space for X1, ’k’ for X1,000, ’M’ for X1,000,000

∙Measurement units - VDC, VAC, OHMS, HZ, C, F, Mx+B (4 characters, left justified)

∙Space(1 character)

∙Alarm indication for Limit-1 (H=High, L=Low, R=Return) (1 character); a blank space = no alarm limit is used, or alarm inactive.

∙Slash (/) used as a separator when either alarm indicator is shown (1 character)

∙Alarm indication for Limit-2 (H, L, R); space = no alarm limit is used, or alarm inactive.

∙Two spaces between channel measurements (2 characters)

∙The following example illustrates this format:

Memory Storage: Computer Interface Control

Memory Storage can be controlled from the front panel or over the RS-232 interface. Refer to Chapter 3 for front panel operation.

Through the RS-232 interface, the PRINT_TYPE and PRINT commands can be used to set up and enable Memory Storage. PRINT_TYPE selects the destination (0 for printer, 1 for Memory Storage, and 2 for both) and the mode used to select the scans to store (0 for ALL, 1 for ALAr, or 2 for trAnS.) PRINT sets storage on (1) or off (0).

The PRINT_TYPE? and PRINT? queries can be used to determine present settings for the PRINT_TYPE (destination, type) and PRINT commands, respectively.

Memory Retrieval

Note

The LOG? query does not return channel numbers with scan data. Therefore, if you add or delete defined channels, you may want to clear the memory contents so that subsequent LOG? queries return only data for the new set of scanned channels.
