Clamp-on Ground Resistance Tester Model 6417 296. MEASUREMENT MODES6.1 Rotary Position W+A6.1.1 Standard ModeSelection of Standard mode is performed in the SET-UP (see § 4.4, menu #9).In Standard mode, only one measurement screen is available. The clampmeasures the loop impedance (W) (at the fixed frequency of 2083Hz) and theleakage current.NOTE: Since the measurement frequency is audible, the operator hears a beepingsignal. This is neither an operating fault nor an alarm, and it cannot be eliminated.This audible signal is amplified by the presence of current in the loop.The alarm thresholds can be configured as desired (see § 4.4, menus #4, #5 &#6).6.1.1.1 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.NOTE: If the measured impedance is less than 1W, the measurement displayalternates between the value measured and the word LOOP, in order to call theuser’s attention to the risk of measuring a local loop at the test point that doesnot include the earth/ground measurement.www.
