Section 2
NOTE: The time interval-based Datalogger records the state of all the alarms at the selected
report time only. Therefore, if an alarm condition resets before the report time, it would
not appear on the report. Use Datalogger Events to log transient alarms. This mode
generates a report upon the detection of an alarm event.
To select Datalogger Data items:
To access the Datalogger Data option list press the <Right Arrow>. Move the cursor to a desired data
item by pressing the <Up or Down Arrow> then <ENT> to select it.
Note that a plus sign (+) appears before the item.
If you select Alarms, the Datalogger logs the state of each alarm function upon generating a report.
A dash [-] represents an inactive alarm. A letter code represents an active alarm:
Alarm Letter Codes and Descriptions
S ....... Spacing ...............Transducer spacing may need re-adjustment
E ....... Empty ..................Pipe is empty
R ....... Rate .................... Flow above High setting or below Low setting
F ....... Fault .................... Three continuous seconds without new data update
A ....... Aeration ...............Current aeration percentage exceeds the alarm setpoint
M....... Memory...............Last valid reading for a selected interval during Fault condition
K ....... Makeup ...............In-Process Makeup occurred
I ........ Interface .............. Liquid Vs exceeds interface alarm setpoint
P........ Pig .......................Pig passage detected (optional)
Z ....... Zeromatic ............ ZeroMatic signal fault
None Default – Datalogging is disabled.

Aeration The aeration percentage recorded at the time of the report.
Alarms The letter codes of any alarms active at the time of the report (see below).
Delta T (uSecs) The Up to Down transit-time difference measured at the time of the report.
Temperature The instantaneous supply aand return temperatures at the time for the report.
Analog Inputs Any data appearing on an auxiliary input at the time of the report.
Chiller Efficiency Instantaneous Chiller Efficiency (CE) for kW/ton, EER and COP appearing on an auxiliary input at
the time of report (optional).
*The Time field expands to HH.MM.SS when you select a logging interval of more that once per minute.
