Current Probe
PS-2184
Introduction
The Current Probe attaches to a PASCO voltage sensor to enable
the measurement of current between −4 A and +4 A. The probe
contains a 0.10 Ω resistor. Current to be measured flows through
the resistor; the voltage sensor measures the resulting potential
across the resistor.
Set-up
1. Insert the probe into a circuit where you want to measure
current. Positive current will flow from the red terminal on
one side to the black terminal on the other side. The voltage
applied across the probe should not exceed 0.4 V. The maxi-
mum absolute voltage of the circuit should not exceed 10 V.
2. Connect the voltage sensor to the side-by-side red and black
terminals.
Note: If you are using the PS-2171 Dual Voltage Sensor, current is select-
able in software as one of the sensor's measurements. For any sensor,
multiply the measured voltage (in volts) by 10 to find the current (in amps).
Specifications
In addition to observing the current probe’s maximum voltage, do not
exceed the maximum voltage of the connected voltage sensor or interface.
Current greater than 4 A or less than -4 A may damage the probe by caus-
ing the resistor to overheat. The time before damage occurs depends on
the current and the initial temperature of the resistor.
