3.2.3 Measurement Settings
In addition to enabling and disabling Wi-Fi, Configuration mode
lets you
set three parameters (current range, aggregation period, and reset to default
recording mode) that affect how the instrument measures and displays data.
3.2.3.1 Current Range
The instrument provides two measurement ranges: 300 A and 3000 A.
The 300 A range provides better resolution but lower measurable current. You
can select the measurement range in Configuration mode.
1.
In Configuration mode
, use the Up ▲ or Down ▼ button to display the
Current Range (I RANGE) configuration screen.
This screen will also show 1, 2, or 3 turns to indicate the instrument’s
configuration for the number of sensor turns (wraps).
You can c
onfigure the instrument for the number of turns in the software
only.
2. Press
to toggle between 360 A and 3600 A.
3.2.3.2 Aggregation Period
When recording data in normal recording mode (see § 4.3), the instrument
performs measurement aggregation. The instrument samples data at a fixed rate
of once per 200 ms and aggregates the samples every second to represent trend
data. In normal recording mode, these 1 s values are aggregated based on a
user-defined period that is set in Configuration mode
. In extended recording
mode, the selected period determines the storage interval for the 1 s values.
1.
In Configuration mode
, use the Up ▲ or Down ▼ button to display the
Aggregatio
n Period (AGG PER) configuration screen.
