Retrieving And Deleting Waveform Recorder Files; Disturbance Recorders - Novatech Bitronics M87X Series Manual

power is removed from the M87x, the relay will revert to the default state. Assigning
the digital outputs to indicate that a waveform record has been created must be performed
by using the 70 Series Configurator. See Section 9 for information concerning output
"Normally Open" and "Normally Closed" settings.
The indication of the status of a waveform record will persist until cleared, except for
Recorder Active, which will reset when the recording is finished. Refer to the appropriate
protocol manual for instructions.
5.4.1c Retrieving and Deleting Waveform Recorder Files
Waveform records may be retrieved and deleted from the instrument using the available
communications protocols. Please refer to the specific protocol manual or section 5.5
(Zmodem and FTP) for details. A file cannot be deleted while being read by another
device.

5.4.2 Disturbance Recorders

The M87x includes two individually configurable Disturbance Recorders. The most
common method of triggering a disturbance event is by using the 70 Series Configurator to
set an upper or lower threshold on one of the measurements. A disturbance record can
also be initiated by a digital input or by a protocol-specific manual command. (See
protocol manual for details on available commands.)
The Disturbance Recorder will archive samples of up to 64 user-selected measurements.
Any measurement made by the device may be selected, allowing the user a great deal of
flexibility in configuring the system. Additionally, the user may configure the Disturbance
Recorder to calculate the min/max/avg of the selected measurements over the interval, or
store only the present value at the end of the interval.
The number of disturbance records that can be stored is dependent on the number of
measurements to record, the measurement type, and the number of pre- and post-trigger
samples selected.
