Storing Saved Readings

To add the current displayed reading to the saved readings memory, press O R (SAVE).

5AVEd appears briefly to confirm the operation and the index number display increments by one.

FULL appears if no room is available in the saved readings memory (after 100 saves).

Saved readings can be viewed later as originally displayed. Actual primary and secondary readings and functions, the time stamp, and display icons are all stored in stored readings memory. (The meter does not save the bar graph.) For example, if the original reading was in volts ac function with the dB modifier selected, the saved reading will contain the saved dB value.

Starting Logging

To begin logging, press O D(LOGGING).

;is shown on the display. The logging interval is preset to 15 minutes.

To change the logging interval, see “Selecting Setup Options” in Chapter 5. The logging interval can be as high as 99 minutes or as low as 1 second. There is enough meter memory for at least 288 intervals (3 days of 15- minute intervals.) Use FlukeView Forms to store additional logging data in your PC's memory.

Note

The meter allows interval logging to begin only if logged readings memory is empty. Refer to the “Clearing Memory” discussion below.

Stopping Logging

Logging stops when one of the following occurs:

You press O N (CANCEL).

A flashing low battery condition (B) occurs.

Logged readings memory becomes full.

You change the rotary switch position.
