30 Clamp-on Ground Resistance Tester Model 64176.1.1.2 Measurement ResultsOnce the measurement has stabilized, the displayindicates:- The leakage current.- The impedance of the loop at the frequency of2083Hz.The impedance is measured only if the leakagecurrent is less than 10A. In the 10 to 40A range,only the current is displayed; the NOISE symbolblinks and the impedance is replaced by dashes.Figure 6-1To store the measurement into memory, press the MEM button (see § 5.8.2).If the contact voltage exceeds 50V, the display indicates the current/impedancemeasurements and the contact voltage alternately.6.1.2 Advanced ModeSelection of Advanced mode is performed in the SET-UP (see § 4.4, menu #9).In this mode, three measurement screens are provided, impedance referredto the chosen frequency and leakage current, contact voltage, display of R(resistance) and L (inductance). The clamp measures the loop impedance(W) at the frequency of 2083Hz. However, in addition to what is measured inStandard mode, the impedance is recalculated at the frequency defined by theconfiguration.The frequency and alarm thresholds can be configured as desired (see § 4.4,menus #4, #5 & #6).6.1.2.1 Making a Measurement■ Turn the rotary switch to the Ω+A position, and wait several secondswhile the instrument performs internal calibration.■ Clamp around the conductor to be measured. If the clamp is incorrectlyclosed, the icon is displayed.■ If necessary, use the HOLD button to freeze the measurement.■ If necessary, use the MEM button to store the measurement.www.
