Page 6: Getting Started
The PA-655 current probe enables a general purpose oscilloscope to display AC and DC current signals up to 100 amps Peak (35A RMS). The PA-655 current probe can also make AC and DC measurements with a multimeter by using the recommended accessory MT-246N (BNC-to-banana) plug adapter. - Page 7 Table 1: PA-655 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.

2. Move the OFF/ Range switch to the 20 mV/A or 200 mV/A position to turn on the probe. (※The PA-655 current probe has a green LED power/battery indicator. If the LED does not light, replace the battery or use specified power adaptor.) - Page 9 See Figure 4. The sensitivity of the PA-655 current probe is multiplied times the number of loops in the jaws. For example: 200 mV/A X 4 turns = 800 mV/A.

PA-655 AC/DC Current Probe. 1. Notes on Battery and Power Converter: The PA-655 current probe uses a single square 9 V battery. This machine is a high power product. Please use the specified alkaline battery. As the battery in the PA-655 current probe is drained, significant gain errors may occur. - Page 11 PA-655 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.
- Page 12 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 PA-655, convenient for storage and shipment. Please do not discard it. If the original packaging is unfit for use or not available, use the following...
