Fluke 1621 Basic Earth Ground Tester Technical Data The Fluke 1621 is an easy-to-use earth ground tester. The first line of defense in detecting reliable ground connections, the unit features basic ground testing methods including 3-pole Fall-of-Potential as well as 2-pole ground resistance. Its convenient size, rugged holster, and large, clear LCD display make it an ideal field earth tester, for most work environments. With a simple user interface and intuitive functionality, the Fluke 1621 is a handy tool for electrical contractors, utility test engineers, and earth ground specialists. 3-pole Fall-of-Potential earth testing for basic measurements 2-pole resistance measurements for added versatility Easily capture values with single-button operation Ensure accurate measurements with automatic noise voltage detection Hazardous voltage warning offers increased user protection Clearly read and record data with a large, backlit display Rugged holster and design for tough work environments Portable size allows for easy transportation Instantly be alerted to measurements outside of your set limit, when you use the adjustable limit setting General specifications Measuring functions 3-pole earth ground resistance, 2 pole ac resistance of a conductor, Interference voltage Intrinsic error Refers to the reference temperature range and is guaranteed for one year Measuring rate 2 measurements/second Battery One 9 volt alkaline (LR61) Battery condition LO-BAT is displayed if voltage drops below 6.5 V Voltages Between jacks H/C2 and E/C1: 250 Veff maximum (effective voltage) Between jacks S/P2 and E/C1: 250 Veff maximum Climatic class VDE/VDI 3540 RZ (conforming to KWG as per DIN 40040, 4/87) Temperature performance Working: -10 C to +50 C (+14 F to +122 F) Operating: 0 C to +35 C (+32 F to +95 F) Storage: -20 C to +60 C (+68 F to +140 F) Reference: +23 C 2 C (+73 F 4 F) Note: If the tester is not going to be used, or is being stored for a long period, remove the battery and store separately from the tester to avoid damage from battery leakage. Note: The four temperature ranges for the tester exists to satisfy European Standards requirements the instrument can be used over the full working temperature range by using the temperature coefficient to calculate accuracy at the ambient temperature of use.General specifications cont.
