1. Safety instructions
•
In order to avoid damage to the sensor resistor,
adhere strictly to the current and power limits
mentioned below.
•
Do not exceed a maximum duration of 15 s for
a maximum current of 20 A, while taking read-
ings. Allow the sensor to cool for 10 mins.
•
Use safety connection leads.
2. Description
Sensor box for measuring electric current in AC and
DC circuits.
Shunt resistance measurement method.
For connecting inputs and outputs, use experiment
leads with 4-mm banana plugs.
CAUTION: This sensor box is not automatically
recognised by the interface.

Accuracy:
•
Insert into the current path via the sockets I+
and I-, maintaining the proper polarity for DC.
When measuring AC, the polarity is not signifi-
cant.
•
Set up a connection from the sockets U+ and
U- to the sockets U
interface, maintaining the proper polarity.
