5.9.2.4 Alarm Acknowledge
The external event can be used as an Alarm Acknowledge. This has the same effect as pushing the ACK
button on the display. Input closed (active) acknowledges an alarm. Use the UP (
↑) or DOWN (↓) Arrow
Keys to select the desired input switch function and press ENTER. The display will return to the “Switch?
1” display.
5.9.2.5 Scale Set
The external event can be used to select which chart scale to use, Scale set 1 or Scale set 2. This works
in conjunction with the Scale Set option in the FUNCtion menu. Scale set 2 can be used for example to
expand the scale values in scale set 1. Use the UP (
↑) or DOWN (↓) Arrow Keys to select the desired input
switch function and press ENTER. The display will return to the “Switch? 1” display.
5.9.2.6 Record Rate
The external event can be used to alter the record sample. If the switch is open (inactive) the recording at
the low record rate, if the switch is closed (active) the recording is at the high record rate. The external input
works in conjunction with the Record Speed option in the FUNCtion menu. The last operation is current -
that is if an external event set the high speed then the user used the menu to set the low speed, the
recording remains at the low speed until the external event is reasserted (in this case inactive then active
again to change back to high speed). Use the UP (
↑) or DOWN (↓) Arrow Keys to select the desired input
switch function and press ENTER. The display will return to the “Switch? 1” display.
Switch 2 and Switch 3 are programmed in the same way as Switch 1 was programmed
5.9.3 Event Messages
The Recorder has three switch inputs that can trigger an event each time the switch opens or closes. Each
time an event occurs a message will be printed on the Alarm/Event Data Log Window and if enabled, is logged
in the Event file on the disk. These messages can be customized by the user. Each message may be 10
characters in length. An Event Message can be programmed for each switch opening and for each switch
closing. The default messages are OPEN and CLOSE, if a message is erased, it will not be displayed or
logged.
NOTE: If the event messages are changed after an event file has been opened on the disk, it is necessary to
rename the alarm file, or use a new disk, in order to reflect the new event message in the file.
