  • Page 2 Instructions A605 500 Amp AC Current Probe 070–8880–00 First Printing: October 1993...
  • Page 5: Product Description

    Product Description The A605 is designed to extend the AC current range of a multimeter up to 500 amps by acting as a proportional current/voltage transformer. It is compatible with multimeters having an AC volts function with an input resistance 1 M .
  • Page 6: Operating Basics

    1. Connect the black lead to the meter COM, and the red lead to the V input. Set the meter to the AC Volts position. See Figure 1 for connection to a Tektronix DM 254. Figure 1: Meter Connections 2. Connect the probe to the circuit by opening the jaws and clamping around the conductor.
  • Page 7 To increase the measurement sensitivity of the A605, loop additional turns of the wire under test through the jaws. See Figure 3. The sensitivity of the A605 will be multiplied by the number of loops in the jaws. For example: 1 mV/A X 4 turns = 4 mV/A.
  • Page 8: Functional Check

    Figure 4. The power consumption of the lamp is usually printed on the lamp. The lamp used should be designed for the test voltage. 1. Connect the probe to the instrument. 2. Connect the lamp to the line voltage. 3. Measure the line voltage at the lamp. A605 Instructions...
  • Page 9 An error of 10% is acceptable, and a good indication that the probe and meter are functioning properly. The linearity of the probe can be checked by the method used to increase measurement sensitivity. By increasing the number of loops in the jaws, the measured current should increase proportionately. A605 Instructions...
  • Page 10: Maintenance

    The box should have a carton test strength of at least 200 pounds. 2. Put the probe into a plastic bag or wrap to protect it from dampness. 3. Place the probe into the box and stabilize it with light packing material. 4. Seal the carton with shipping tape. A605 Instructions...
  • Page 11: Specifications

    Specifications These characteristics apply to a A605 probe installed on a Tektronix DM254 multimeter in an environment within the limits described in Table 3. For best results, a true RMS multimeter should be used. Table 1: Electrical Characteristics Output 1 mV/A Accuracy 2.5% from 4 to 500 A, 0.6A...
