Description
Response to an attempt to save site data, when data memory is full. Delete an obsolete
site or clear Datalogger memory to make room for the new data.
Memory read error occurred while accessing the active site data.
Response to an attempt to invoke an operation that requires a channel to be enabled.
Enable the channel [Channel Setup - Channel Enable - Yes]. Note that a channel cannot
be enabled until its sensors are operating.
Response to pressing and holding <ENTER> key during power-up. Use this function to
restore operation if a severe event (e.g. a violent power surge) disrupts the system operation.
[Clr Saved Data?] only appears after pressing the <ENTER> key and then pressing the
<Right Arrow> in response to [Clr Active Memory?]. Answering Yes to [Clr Saved Data?]
will erase ALL saved data. To invoke in RS-232 serial mode, type @@@ and then press
<ENTER> key.
Response to a request to output Datalogger data to the printer or the Graphics screen when
no Datalogger data exists. Set up the Datalogger.
<ENTER>.
Prompt to fill the pipe during the Actual MTY procedure. After filling the pipe, press
<ENTER>.
Response while trying to recall/delete a site setup when no sites are stored.
Upon measuring the liquid sonic velocity (Vs), the meter recommends re-spacing the
sensors to improve performance.
During the Initial Makeup the system detects invalid sensor spacing, erroneous liquid pipe
parameters, or some other factor that prevents it from completing the Initial Makeup. This
may be due to one of the following:
● An out-of-range data entry.
● An invalid condition (e.g., overlapping sensors in Reflect Mode). If selecting Direct Mode
does not resolve, review all site setup and sensor installation choices particularly data
entered for pipe and liquid.
● In Reflect Mode the flow meter detects that the pipe wall signal may infringe upon the
liquid signal. Use Direct Mode instead.
● Press <ENTER>, <Up Arrow>, <Down Arrow>, or <Left Arrow> to abort install routine.
Continue programming other site data in anticipation of resolving the difficulty later. Call
technical support for help if necessary.
