1623-2 Users Manual Description of Functions The functions are selected with the central rotary switch. Measurement values are shown on a liquid crystal display with correct decimal point and unit. Additional special characters indicate measurement mode, operating condition, and error messages. The Tester includes these measurement functions: • Earthing Resistance (RE) • Selective Measurement of Earthing (RE ) • Low Battery Indicator The earthing resistance is determined by a 3-pole or 4-pole current and voltage measurement. The measuring voltage is a square pulse ac voltage with 48 / 20 V and a frequency of 94, 105, 111 or 128 Hz. The frequency can be selected manually or automatically (AFC). Measurement of a single earth electrode in a mesh operated (parallel) earthing system. The current flowing through the single earth electrode is measured with an external current transformer. Battery voltage is low, replace batteries. 10 MyFlukeStore Shop for Fluke products online at: www. .com 1.877.766.5412

Description of Functions
The functions are selected with the central rotary switch. Measurement values are shown
on a liquid crystal display with correct decimal point and unit. Additional special
characters indicate measurement mode, operating condition, and error messages.
The Tester includes these measurement functions:
•
Earthing Resistance (R
E
)
The earthing resistance is determined by a 3-pole or
4-pole current and voltage measurement. The
measuring voltage is a square pulse ac voltage with
48 / 20 V and a frequency of 94, 105, 111 or 128 Hz.
The frequency can be selected manually or
automatically (AFC).
•
Selective Measurement of
Earthing (R
E
)
Measurement of a single earth electrode in a mesh
operated (parallel) earthing system. The current flowing
through the single earth electrode is measured with an
external current transformer.
•
Low Battery Indicator
Battery voltage is low, replace batteries.
