OMNI-4000 S/N 6705 and above ENMET Corporation

1.9.2 Data Available

The device computes, for each channel in use and at a rate of once per second, an average on a period of one minute.

The averaged data is stored in the memory. The following data can be read from the OMNI-4000 serial port:

• A personal computer with the COM4000 Communications software can be used to display the average readings

per minute.

• A serial printer can be used to printout the data relating to the average for each quarter of an hour. Thus, a print-

out shows the average reading over a period of 15 minutes; this new average is calculated by the OMNI-4000

during the printing.

1.9.3 Length of Data Storage

The data stored by the OMNI-4000 are held even if the device is left unused for a long period. The storage duration

is 3 to 5 years and is dependent on the life of the internal lithium battery.

1.9.4 Clearing the Stored Data

To clear the data, touch the ENTER switch; to retain the data, touch the BACKLIGHT switch.

This is performed by means of a request on the display after the printout of the stored data. Displayed alternately are:
