5.7.2 Alarm on/off
This option enables the user to enable or disable the recording of Alarm and Event information to disk/card.
To enable or disable the recording of Alarm/Event information:
From the Record Setup menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Alarm on/off and press the
ENTER button. Press the YES or NO button to select either record alarms=YES (to enable Alarm/Event
recording) or record alarms=NO (to disable Alarm/Event recording) and then press the ENTER button to return
to the Record Setup menu. No data will actually be stored until the Recorder is set to Record On under the
Record On/Off menu option in the FUNCtion Menu.

5.7.3 Record Modes

There are two Record Modes that can be set: Fill Mode and Data Mode. The Fill Mode determines whether files
are to be recorded to fill the disk and stop, or recycle, deleting the oldest data and replacing it with new. The
Data Mode options determine whether data will be averaged over the record interval or whether the latest data,
peak value or valley value is stored. If you are using one of the intrinsic functions of the unit, for example peak
values, you must set the sample mode to instantaneous or you will average your peaks if you have a slow
sample storage rate.
To set the Record Modes:
From the Record Setup menu, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Record Modes and press the
ENTER button. The Record Modes Setup menu will display three options: Fill Mode, Data Mode All and
Data Mode Indiv. These options are described in the following sections.

5.7.3.1 Fill Mode

The Fill Mode determines how the data fills the disk/card. There are two Fill Mode options available: Fill to
End and Cycle Data.
To set the Fill Mode:
From the Record Modes Setup menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Fill Mode and press
ENTER. The current mode will appear highlighted. Use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to select either Fill
to End or Cycle Data as desired and press the ENTER button to activate. Press the EXIT button to return to
the Record Modes Setup menu.
5.7.3.1.1 Fill to End
The Fill to End option sets the unit to record to disk/card until the disk/card is full and then it will shut
the recording off.
5.7.3.1.2 Cycle Data
The Cycle Data option sets the unit to continue recording to disk/card until the disk/card is almost full
and then it will start to write over the earliest data a block at a time (about 500 samples at a time). The
disk/card will always contain the most current data, and the oldest data will be lost. All points respect
the integrity of data for other points, each point will only replace it's own data.
NOTE: Set the Disk Full Alarm threshold to 100% when running in the cyclic mode to prevent the Disk
Full Alarm from activating (see Section 5.7.7.1).
