4.4.1 OUTPUT DATALOGGER
This menu cell allows you to send the Datalogger contents to an external device (usually a
computer or printer) via the meter’s RS-232 Serial I/O port. This command is effective only
after a successful install. In addition, you have to enable datalogging and select data items
in the Datalogger Setup menu. Note: This command sends the data collected by both chan-
nels of a dual-channel system. Therefore, you should include [Site ID] (i.e., current site setup
name), [Date] and [Time] in your report so that you can identify the source of each report.
The meter interfaces with most serial printers or personal computers. Controlotron offers
the Model 996P portable serial printer. You must use the proper cabling between the flow
computer and the external device. In addition, you must configure the RS-232 Setup correct-
ly. You should turn off the Datalogger function before you transmit an extensive printout.
This will avoid contaminating the printout with new Datalogger data. Datalogger reports
are sequential ASCII text files.
NOTE: The meter suspends measurement while it transmits serial data.
To send Datalogger contents to the RS-232 Serial Port:
Check the computer-to-external device connections and your RS-232 Setup para-
meters (see paragraph 4.8, RS-232 Setup).
To access the [Output Datalogger] option list press
Scroll the cursor to [Yes] by pressing
To transmit Datalogger contents to external device via the serial port press
To stop printout press
4.4.2 CIRCULAR MEMORY
In its default mode, the Datalogger collects data until its memory becomes full. At that time
the flowmeter suspends data logging and cannot resume until the datalogger memory is cleared
(see Clear Datalogger command). Multi-Channel systems include Circular Memory and Single
Channel systems do not. Circular Memory allows the Datalogger to ”‘write over” its oldest
records when memory reaches full capacity. If you enable Circular Memory, you are assured
of always collecting the most recent data. But, also remember that you will lose the oldest
Datalogger reports. Note further that invoking Circular Memory deletes the current contents
of the Datalogger and pre-allocates a substantial amount of memory for this function, remov-
ing it from site storage memory.
NOTE: To avoid potential data loss, the meter prevents you from altering this setting
while the Datalogger is active.
To setup and enable Circular Memory:
The Datalogger Mode menu must have the [Memory] menu cell selected.
Datalogger items must be selected (e.g., Site ID, Date, Time, etc.).
In the Datalogger Control menu, select [Circular Memory].
Press to access the [Circular Memory] option list.
