Instruction Manual Safety Instructions This section contains instructions that must be observed to keep this oscilloscope accessory operating in a correct and safe condition. You are required to follow generally accepted safety procedures in addition to the precautions specified in this section. The overall safety of any system incorporating this accessory is the responsibility of the assembler of the system.
CP031 Current Probe Never install or remove the probe on bare conductors which are energized. The transformer core and shield are grounded but not insulated and may contact the conductor when the locking lever is open. To avoid short circuits and accidents that could result in injury or death, use the CP031 current probe only with conductors carrying 300 V or less.
Instruction Manual Overview Description The CP031 uses a combination of Hall effect and transformer technology which enables measurements to be made on DC, AC and impulse currents. It has a 100 MHz bandwidth and is designed to measure continuous currents up to 30 Amp. The probe can be used with a WaveSurfer, WaveRunner 6000, or WavePro 7000 series oscilloscope with firmware 4.3.0.0 or higher. With the ProBus interface, the CP031 becomes an integral part of the oscilloscope.
CP031 Current Probe Operation Precautions The sensor head is a precision assembly consisting of a molded component with a ferrite core and a Hall effect element. It may be damaged if subjected to sudden changes in temperature, mechanical strain or shock. The mating surfaces of the sensor are precision ground and should be treated with care. If there is any type of dust or dirt on the mating surfaces of the sensor head, measurements may be impaired.
Instruction Manual Operation with a Teledyne LeCroy Oscilloscope The probe can be controlled through the Vertical Setup dialog for the channel to which the probe is connected. Turning the VOLTS/DIV knob will control the oscilloscope’s scale factor to give full dynamic range from 20 mA/div to 50 A/div.
CP031 Current Probe Care and Maintenance Cleaning The exterior of the probe and cable should be cleaned only using a soft cloth moistened with water or isopropyl alcohol. The use of abrasive agent, strong detergents or other solvents may damage the probe. CAUTION. The probe case is not sealed and should never be immersed in any fluid. Calibration Interval The recommended calibration interval is one year. Adjustment should only be performed by qualified personnel.
Instruction Manual Returning a Defective Probe Contact your local Teledyne Lecroy sales representative to find out where to return the product. All returned products should be identified by model number and serial number. Provide your name and contact number and if possible describe the defect or failure. In case of products returned to the factory, a Return Authorization Number (RAN) must be used. Contact your nearest Teledyne Lecroy office, or the New York Customer Care Center, to receive a RAN.
CP031 Current Probe Performance Verification This procedure can be used to verify the warranted characteristics of the CP031 Current Probe. The recommended calibration interval for the model CP031 Current Probe is one year. The complete performance verification procedure should be performed as the first step of annual calibration. Performance verification can be completed without removing the probe covers or exposing the user to hazardous voltages.
Instruction Manual Description Minimum Requirements Test Equipment Examples Calibration Fixture, 100 Turn Loop 100 Turn loop in series with 0.5Ω ± 0.
CP031 Current Probe Check LF Accuracy Figure 1. LF Accuracy Test set up. 1. Set the Function generator to 50 Hz sine wave. Output voltage at 3 Vrms with 50Ω output. 2. Remove the CP031 from the oscilloscope and reconnect using the ProBus extension cable. Connect the BNC male connector of the ProBus extension to DMM #1 using a BNC Female to Dual Banana adapter. 3.
Instruction Manual Adjustment Procedure This procedure can be used to adjust the warranted characteristics of the CP031 Current Probe. This procedure should be used if a parameter measured in the Performance Verification Procedure is outside of the specification limits. Adjustment should only be performed by qualified personnel. The warranted characteristics of the CP031 Current Probe are valid at any temperature within the Environmental Characteristics listed in the Specifications.
CP031 Current Probe Preliminary Procedure 1. Remove the probe compensation box circuit board by removing the two screws from the cable end of the compensation box and sliding the circuit board out of the box. 2. Connect the CP031 compensation board to the channel 1 input of the oscilloscope through the ProBUS extension cable, and completely close the probe slider. 3.
Instruction Manual 5. Set both DMMs to measure AC Volt. 6. With the CP031 removed from any signal and the slider returned to the LOCKED position, degauss the probe by touching DEGAUSS (on the CP031 dialog), then OK. 7. Open the CP031 slider and position the probe input around the 100 Turn loop. Close and LOCK the slider. 8. Adjust the Function Generator voltage until the voltage measured at the 'Current Sense' terminals (DMM #2) is 50 mV ± 0.05 mV. (This corresponds to 10 A at the probe head). 9.
