Recording function
External memory media:
Compact Flash card
Format according to FAT16 or FAT. Otherwise, reading and saving are impos-sible.
Recording capacity:
1 GB maximum (compact flash). Limiting the recording file to 64 MB is recom-mended (for 112 hours if display refresh cycle is 1 second. See Table 1 (p. 6).) If impossible, up to 256 MB is tolerated. A file recorded beyond could not be opened.
* Please change the compact flash every six month to prevent the data losing.
Recording method:
Turning ON the REC key allows measured data to be written at fixed cycles.
Recorded as a new file whenever the recording starts.
Data save cycles:
Linked to the display refreshment cycles on the ”Real Time Trend” screen. How-ever, they are automatically set to about 1 minute if the refreshment cycles are set to less than 1 minute.
Trend data: Measurement data sampled at measurement cycle is saved in terms of mean value, instantaneous value or maximum/minimum value.
Event data: Saves alarm data and message data.
Further saves power ON and OFF, if any, after starting recording.
Totalizing value data:
Total izing value data at designated timing is recorded per channel .
Totalized value data at designated totalized value recording cycle or the sum total is recorded in the totalizing file. You can choose which type you want to record.
For each cahnnel. it can be select as totalizing action from Analog input to-talization, Digital input count or period of Digital input ON, and it can be select as totalizing period type from Dairy, Weekly, Monthly, Annual , Periodic, Dairy (time set) or External input signal. Even if a power failure occues during totalization and then the power is restored,the totalization restarts from the value before power failure.
Configuration data:
Configuration data can be saved. And this data can also download to recorder.
Storage capacity :
Approximately 3 years when the display refresh cycle is 30 seconds (in case of 9-channel recording in ASCII data format, and 512 MB compact flash used). Refer to Table 1.
Residual capacity of memory:
Indicates how much of the memory card has been used on the screen. If the residual capacity is none, the recording stops.
Compact flash card form: PHZP1301-512
(CF card) (If a card other than the above is used, no operation assurance is ensured. Meanwhile, as for other CF cards for which operation check will have been completed, the results will be posted on our company's homepage sequentially. Please refer to this website.)
Data format: Either of ASCII or binary format can be selected. (Switching cannot be made while the recording is in progress. In the case of ASCII format, the data can be directly read on Excel, etc. The data recorded in binary format cannot be read directly.)
Approximately 166 bytes per sampling for maximum/minimum recording of 9-channel input in ASCII format, or approximately 40 bytes for maximum/minimum recording of 9-channel input in binary format.
