*Logging: PASCO wireless sensors can either stream
live data to a compatible device for “real-time” viewing or
log data (save it to the sensor’s memory). After logging,
the data can be uploaded to the computing device for
display and analysis at a later time. Logging capability
supports long-term or remote data collection while not
connected to a device.
Check the PASCO Web page at:
www.pasco.com/software
for the latest software version.

Connecting the Sensor for Measurement
Current is measured through an electric circuit. For that
reason, the Wireless Current Sensor is always con
-
nected in “series” in a circuit. The sensor is a part of the
circuit.
For example, in the diagram, the Wireless Current Sen
-
sor is connected in series with a resistor (“load”) that is
in series with a battery (”source”). The Wireless Current
Sensor measures the current “through” the circuit.
Protection
The Wireless Current Sensor has built-in protection
against damaging over-current. If the current exceeds
±2 amps, the sensor will make a sonic alarm and the
status LEDs will both shine red.
If this happens, take the steps necessary to reduce or
stop the current through the sensor. For example, dis
-
connect the power source. Analyze the circuit to deter
-
mine why the over-current happened, and don’t
reconnect the power source until the problem is fixed.
Set Up the Software
SPARKvue
Connecting the Wireless Sensor to a Tablet or a
Computer via Bluetooth
•
For SPARKvue, select the Bluetooth icon (
) to
open the Wireless Devices list. In the Wireless
Devices list, the sensors are ordered by proximity to
the device.
•
Select the correct address that matches the
XXX-XXX number found on the sensor.
•
Select Done. A list of measurements appears under
the sensor in the Home Screen.
