Operator’s 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.
ADP015 Current Probe Observe all terminal ratings. To avoid electric shock or fire, do not use the probe above the current & voltage limits shown on the probe as well as all accessories. Do not remove probe casing. Removing the probe’s case or touching exposed connections may result in electric shock. Use indoors only. Use only within operational environment listed. Do not use in wet or explosive atmospheres. Keep product surfaces clean and dry. Clean with a cloth moistened in water or alcohol.
Operator’s Manual Specifications The following specifications are valid for model AP015 current probes after the probe has reached operating temperature, which is 20 minutes with power applied in a environment with stable ambient temperature. The probe must be operating within the environmental conditions listed in the General Characteristics section, and has been calibrated within the past 12 months in an ambient temperature of 23 ±5 °C.
ADP015 Current Probe Typical Electrical Characteristics Typical characteristics describe parameters which do not have guaranteed performance, however are representative of the average performance from a sample of several probes. Tests for typical characteristics are not provided in the Performance Verification Procedure. Rise Time: < 7 ns Slew Rate: > 1.6 A/ns (sensitivity ≥ 1 A/div) Insertion Impedance: < 0.

ADP015 Current Probe Preliminary Procedure 1. Connect the AP015 to the channel 1 input of the oscilloscope, and completely close the probe slider. 2. Turn the oscilloscope on and allow at least 30 minutes warm-up time for the AP015 and test equipment before performing the Verification Procedure. 3. Turn on the other test equipment and allow these to warm up for the time recommended by the manufacturer. 4.
Operator’s Manual Performance Verification Procedure The warranted characteristics of the AP015 Current Probe are valid at any temperature within the Environmental Characteristics listed in the Specifications. However, some of the other test equipment used to verify the performance may have environmental limitations required to meet the accuracy needed for the procedure. Make sure that the ambient conditions meet the requirements of all the test instruments used in this procedure.
ADP015 Current Probe 8. Check that this frequency is greater than 50 MHz, and record the frequency on the test record. B. Check DC Accuracy 1. Set the DC Power Supply output voltage to approximately 0 V. 2. Remove the AP015 from the oscilloscope, and reconnect using the ProBus extension cable. Install a BNC T connector, BNC cable, and BNC to dual banana plug adapter as shown in the figure on the following page. Connect the dual banana plug adapter into one of the digital multimeters. 3.
Operator’s Manual 6. Open the AP015 slider and position the probe input around the 50 Turn loop. Close and LOCK the slider. 7. Set the oscilloscope channel vertical scale to 20 A/div. 8. With the power supply set to 0 V, press the 'Null' button of the multimeter measuring the probe voltage to subtract the probe's offset voltage from the measurement. (If the multimeter being used does not have this capability, the offset value can be manually subtracted from the probe output values recorded below.) 9.
ADP015 Current Probe 18. Verify that the 30 A Accuracy is < ±2%. 19. Leave the connection set up for the remaining test. C. Check Peak Current CAUTION. This test increases the power dissipated inside the probe. Do not leave the increased current turned on longer than needed to complete the test (10 seconds. 1. Increase the power supply voltage until the voltage measured at the 'Current Sense' terminals is > 500 mV. (This corresponds to > 50 A at the probe head.) 2. Note the probe output voltage.
Operator’s Manual CAUTION. The adjustment procedure requires removal of the instrument covers. These covers are part of the ESD protection system of the AP015. To protect the instrument, the entire procedure should be performed on a static dissipating work surface only. The technician should wear an antistatic grounding wrist strap and follow standard static control procedures. Test Equipment Required The adjustment procedure requires a subset of the equipment required for Performance Verification.
ADP015 Current Probe Adjust R24, Gain 1. With the AP015 Current Probe removed from any signal and the slider returned to the LOCKED position, degauss the probe by pressing the DEGAUSS button (located on the coupling menu) twice. 2. Connect the AP015 to the 50 Turn loop, and set the oscilloscope vertical scale to 20 A/div. 3. With the power supply set to 0 V, press the 'Null' button of the multimeter measuring the probe voltage to subtract the probe's offset voltage from the measurement.
