Digital Recorder
Action Triggers the allocated control function on the device when activated.
The following actions are available:
•
Start recording
•
Set-up lock
•
Time synchronisation
•
Ext. inter. analysis
•
Prefix change
•
Rear illumination off
•
External cycle
"Start recording" When the channel is activated, signal recording of all channels is started and
not ended until the channel is deactivated again.
"Set-up lock" As long as the control input is activated, the "Set-up" key is accessible. The set
parameters can be displayed or changed until the control input is deactivated
again.
"Time When the input is activated (signal leap from Low to High), the internal second
synchronisation" counter is set to zero. If the second indicator is between 0 and 29, the minutes
remain unchanged. If the second indicator is between 30 and 59, the minutes
are increased by one.
Tip: use this function in conjunction with a master clock. All devices used in this
way run synchronously. Any signals measured on different devices can be
clearly compared with each other chronologically.
"Ext. inter. analysis" As long as the control input is activated, all active channels are analysed, i.e.
the analysis of min./max. values and averages is not made in cycles at fixed
intervals / intermediate analyses, rather it is controlled via this digital input. The
analysis starts when the input is activated. It is completed and saved when
deactivated.
Example: Acquiring minima, maxima, averages and quantities
#
Under "Signal analysis", "Intermed. analysis" must be set to "Extern".
"Prefix change" Changes the counting direction for the pulse counter.
"Rear illumination The rear illumination is switched off when the digital input is activated
off" ("screensaver": screensaver increases the service life of the rear illumination).
The device's remaining functions (e.g. storage, limit value monitoring, etc.) are
not affected by this.
"External cycle" Save cycle defined via control input: a control input must be set to "External
cycle" for this. Then, provided this is activated, data is recorded with the speed
set under "Basic settings, External cycle" instead of with the standard save
cycle.
Copy settings Copies the settings of the current channel into the selected channel (including
limit values). Both of the last positions of the target channel's designation are
replaced with its channel number.
Tip:
Makes device setting easier, if the same settings apply largely for several
measuring points.
