  • Page 6: 2100 Electrical Test Equipment Calibrator Introduction

    A complete electrical test equipment calibration solution from one instrument. Designed to provide an accurate cost effective portable instrument for the calibration of Insulation testers, RCD testers, LOOP testers and PATs the 2100 calibrator can be ProCal combined with the Calibration System to allow automated calibration.

  • Page 7: Installation & Power Requirements For The 2100

    There should only be a small voltage between Phase (Neutral) and Phase (Earth). To keep the LOOP impedance value to a minimum, the mains input to the 2100 is of a direct cable type. This avoids any introduction of unnecessary impedance.
  • Page 8 Designed for on use in the laboratory or portable on site calibration. The 2100 calibrator is equally suitable for use in the standards laboratory or for on site calibration work. The Small footprint and low weight makes the 2100 calibrator ideal for on site calibration.

  • Page 9: Preparing The Calibrator For Use

    2100 Operation Manual Preparing the calibrator for use. Initial Inspection. After shipment the calibrator should be inspected for any signs of external damage. Should external damage be found contact the carrier immediately. Do not connect a damaged instrument to the line power as this may result in internal damage. Please keep the original box which can be used when returning the calibrator for service and re-calibration.

  • Page 36: Introduction To Loop Testers

    2100 Operation Manual Introduction to LOOP Testers What is the loop ? When an appliance is connected to the mains supply a circuit is made. It completes the loop current flow round the circuit loop from the power station in the live wire through the appliance and then back to the power station in the neutral wire.
  • Page 37 The value displayed on the tester can then be compared to that of the known value of the resistor. plus the loop resistance of the supply. The 2100 has 8 calibrated resistance values which are non inductive and are able to withstand the 23 Amps needed.
  • Page 38 (Note this is not the value of the socket the 2100 is plugged in to but the value at the test socket, which is always greater due to the resistance added by the 2100 wiring.) How can I calibrate a Loop Tester at Zero It is desirable when calibrating loop testers to calibrate at as near zero as possible.
  • Page 39 Remember every switch, fuse socket, even the 2100 will add resistance. If it is required to calibrate at values below that available from of the 2100 then a short length of extension cable of which the resistance of the live + earth conductors have been measured by a 4 wite DMM can be used.
