Fluke 1623 Fluke 1623 and 1625 Geo Earth Ground Testers Datasheet - Page 2

The most complete testers The Fluke 1623 and 1625 are distinctive earth ground testers that can perform all four types of earth ground measurement: • 3- and 4-Pole Fall of Potential (using stakes) • 4-Pole Soil Resistivity testing (using stakes) • Selective testing (using 1 clamp and stakes) • Stakeless testing (using 2 clamps only) The testers are also easy to use. For each test, the testers inform you which stakes or clamps need to be connected and the large rotary switch can be used even with a gloved hand. The complete model kit comes with the 1623 or 1625 tester, test leads, 4 earth ground stakes, 3 cable reels with wire, 2 clamps, batteries, and manual-all inside a rugged Fluke carrying case. 1623 Specifications General Display:1999 digit LCD User interface Robust and waterproof Display with special symbols, digit height 25 mm, fluorescent backlight Instant measurement through TURN and START one button concept. The only operating elements are rotary switch and START button Instrument is designed for tough environmental conditions (rubber protective cover, IP56) Temperature ranges Working temperature Operating temperature Storage temperature Reference temperature -10 °C to 50 °C (14 °F to 22 °F) 0 °C to 35 °C (32 °F to 95 °F) -20 °C to 60 °C (-4 °F to 140 °F) 23 °C to ± 2 °C (73 °F to ± 4 °F) The chart of four temperature ranges for the instrument exist 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.
