The GCP-300 current probe enables a general purpose oscilloscope to display AC and DC current signals up to 200 amps Peak (140A RMS). The GCP-300 current probe can also make AC and DC measurements with a multimeter by using the BNC-to-banana plug adapter.

Table 1: GCP-300 controls and indicators Control/Indicator Description Current flow symbol. The arrow shows the probe’s polarity convention for measuring current flowing from positive to negative. Zero adjustment. Rotate to adjust the probe output to zero when there is no current present. It may also be used to offset a DC signal component.
Do not clamp the probe onto circuits with voltages greater than 600 VAC. Personal injury or damage to the probe may result. Always connect the GCP-300 current probe output to the instrument before clamping onto the circuit under test. 1. First connect the current probe BNC connector to double BNC connection cable then connect to oscilloscope input.

See Figure 4. The sensitivity of the GCP-300 current probe is multiplied times the number of loops in the jaws. For example: 10 mV/A X 4 turns = 40 mV/A.
Use the information in this section to properly maintain the operation of your GCP-300 AC/DC Current Probe. 1. Notes on Battery and Power Converter: The GCP-300 current probe uses a single square 9 V battery. This machine is a high power product. Please use the specified alkaline battery.
GCP-300 has in its design a priority external power circuit therefore it is safe to simultaneously install the battery and the external power supply. During usage, removing the external power supply will not produce waveform anomaly or any damage. However when external power is used for an extended time (more than 1 week), removal of battery is recommended.
Do not clean with solvents or abrasives. Do not immerse the probe. 4. Preparation for Shipment Our company has designed a special box to be used for GCP-300, convenient for storage and shipment. Please do not discard it. If the original packaging is unfit for use or not available, use the following...
Specifications: These characteristics apply to an adjusted GCP-300 AC/DC Current Probe installed on an oscilloscope of any brand. The oscilloscope must be warmed up for at least 20 minutes and be in an environment with the temperature at 10°C ~30°C and the humidity at 0~80%.
