The “Logging Parameters” panel shows timing
parameters for the logger functions within
Sentinel 2.
For Sentinel 2, the built-in logger should be
set for the measurement interfaces to be
logged frequently.
Therefore, set to “Log data
at specified time interval”.
The “Sample Interval” is used to produce a set of
data for the purpose of applying optional statistical
functions (e.g. Average).
The “Log … interval”
specified time is used to save a
datapoint once any statistical functions have been applied to the latest set of
measurements.
The settings shown here are typical for Sentinel operation.

Sentinel can be setup to call into the HWM DataGate server (over the mobile phone
network) at specific times. During a call-in it will send measurement data or receive
“remote programming commands”.
The installer should setup Sentinel2 with the required schedule.
Note: If more than two call are required per day, an external battery pack will be
required. Without an external battery providing power, Sentinel2 will restrict
itself to two calls per day, maximum.
Unsent data will be stored in the unit and will be sent at next call-in.
4.20.1
Call-in times (schedule and protocol)
IDT displays a table for the setting of the call-in
pattern.
A selector on the first line determines if the
unit will call-in at regular intervals (select a
mode of
“Freq”) or at specific times
(select a
mode of “Time”)
.
