Slate Memory Mode

Appendix B

Slate Memory Mode

Slate mode causes logging to stop when memory becomes full. The sampler continues to operate but no more data is logged. Use this mode to keep data from the beginning of the logging period.

Wrap Memory Mode

In Wrap mode, when memory becomes full, the oldest reading is discarded each time a new reading is taken. When memory becomes full, the sampler continues to operate and log data. This mode is best used when interested in the most recent data readings.

Memory Mode Configuration

To configure the Memory Mode for either Slate mode or Wrap mode:

1.Select Data Log from the Advanced Options menu.

2.Select Memory Mode using the UP and DOWN keys, then press ACCEPT.

3.Press CHANGE CHOICE to choose either Slate or Wrap, then press ACCEPT to complete.

Data Logging Configuration

To configure the sampler for data logging:

Note: If logging is enabled on any channel, then that channel will have an arrow in front of it to signify that the channel is logged.

1.Select Data Log from the Advanced Options menu.

2.Highlight Select Inputs using the UP and DOWN keys and press SELECT.

3.Highlight the channel you wish to log using the UP and DOWN keys, then press SELECT.

4.Press CHANGE CHOICE to cycle between Logged and Not Logged, then press ACCEPT.

5.Enter a logging interval using the numeric keypad, then press ACCEPT. Valid logging intervals are shown on the status bar along the bottom edge of the display for your reference.

6.Select another channel to configure or press RETURN to back up one step or press MAIN MENU to return to the Main Menu display.

Diagnostics

From the Main Menu, select OPTIONS> ADVANCED OPTIONS > DIAGNOSTICS.

In addition to the automatic diagnostics that are performed upon power up, the following manual diagnostics are available:

•	Distributor Test	•	LCD Test
•	Event List	•	Liquid Sensor
•	Keypad Test	•	Velocity Analysis
