Clearing Memory 4

Clearing Memory

You can clear memory in two ways.

First, If the rotary switch is in the VIEW MEM position, you can press the blue button (%) to activate the CLEAR MEM function. CLr.? appears in the display.

You are then prompted to press [ (YES) to clear the type of memory presently in use or ] (NO) to stop the clear procedure. The display defines the type of memory to be cleared, as:

; to clear logged readings memory.

MEM to clear saved readings memory.

A second clearing procedure is required when you try to start logging and the logged readings memory is not empty.

CLr.? appears in the display. To clear the logged readings memory and begin logging new data, Press [ (YES).

To decline the clearing operation and not begin logging, press ] (NO).

If you attempt to save a meter reading when saved readings memory is full, FULL appears in the display. You must use the VIEW MEM function to clear saved readings memory before proceeding.

Using Communications (187 and 189)

When using a PC-to-meter IR (infrared) communication link, refer to the FlukeView Forms Installation Guide or the on-line help.

You can use the IR communication link and FlukeView Forms software to transfer the contents of a meter’s memory to a PC.

Note

The 187 and 189 will log in real time mode to a connected computer running FlukeView Forms.

In addition, the 189 allows the user to log to internal memory and connect to the computer later for download.

FlukeView Forms allows you to place the data into standard (default) or customized forms. The forms can display the data in table and graph form, as well as view user comments. You can use these forms to satisfy ISO- 9000 and other documentation requirements.
