Included Parts

• Voltage-Current Sensor

• 4 mm banana plug patch cords, 5 pieces

• Alligator clip adapters, 4 pieces

Additional Part Required

PASPORT interface or datalogger

Quick Start

1. Connect the Voltage-Current Sensor to your PASPORT inter­face.

2. If you are using a computer, connect the PASPORT interface
to it and start DataStudio.

3. Press or click the start button to begin recording data.

Introduction

The Voltage-Current Sensor measures voltage and current simul­taneously and calculates power.

Set-up

Connecting the Voltage-Current Sensor to an
Interface

1. Connect the sensor’s plug to any port of a PASPORT inter­face or datalogger.

Connecting the Voltage-Current Sensor to a
Device

To Measure Voltage

Connect the voltage leads across a battery (Figure 1), power
source, or circuit element. The sensor measures the potential dif­ference between the positive (red) and negative (black) leads.
The measurable potential difference range is -10 V to +10 V.

The voltage anywhere in the connected circuit or device should
not exceed 10 V above or below earth ground.

Figure 1: Measuring voltage

To Measure Current

Use the included patch cords to insert the sensor into a circuit as
illustrated in Figure 2. The sensor measures current flowing
through it with current flowing from the positive terminal to the
negative terminal measured as positive current. The measurable
current rage is -1 A to +1 A.

The voltage anywhere in the connected circuit or device should
not exceed 10 V above or below earth ground.

Connect the sensor in parallel with the load. Do not connect the
current terminals of the sensor to a battery or power supply with­out a load; this will create a short circuit.

2. If you are using a computer, connect the PASPORT interface
to it and start DataStudio.

About the Measurements

Voltage, Current, and Power

The sensor measures voltage and current. From these two mea­surement, it calculates power, which is the product of voltage and
current. All three of these measurement are recorded by the com­puter or datalogger. To view any measurement, select it in soft­ware or on the datalogger.

Sampling Rate

By default, data is recorded at a rate of 10 samples per second.
The sampling rate can be decreased or increased (up to 1000
samples per second) in software or on the datalogger.

Overcurrent

If current through the sensor exceeds ±1 A, the overcurrent alarm
sounds. Reduce the applied current.

If current exceed ±1.1 A, the resettable fuse trips. Disconnect the
leads from the current terminals for a few seconds to reset the
fuse. Correct the problem that caused the overcurrent before
reconnecting the sensor.
