Features
The 1625-2 Earth/Ground Tester (Tester) is an earth resistance meter with fully
automated measuring frequency selection process. The Tester includes automatic testing
of probe and auxiliary earth electrode resistances and possible interference voltages in
accordance with DIN IEC61557-5/EN61557-5:
automated measuring frequency selection process. The Tester includes automatic testing
of probe and auxiliary earth electrode resistances and possible interference voltages in
accordance with DIN IEC61557-5/EN61557-5:
•
Measurement of interference voltage (U
ST
)
•
Measurement of interference frequency (F
ST
)
•
Measurement of probe resistance (R
S
)
•
Measurement of auxiliary earth electrode resistance (R
H
)
•
Measurement of earthing resistance 3-pole, 4-pole, (R
E
) with or without using the
external clip-on current transformer for selective measurement of single earthing
branches in mesh operated earthing systems
branches in mesh operated earthing systems
•
Resistance measurement 2-pole with ac voltage (R~)
•
Resistance measurement with dc voltage 2-pole, 4-pole, (R)
With its various possibilities of measurement and the fully automated measuring
sequence control (incl. automatic frequency control AFC), this instrument offers the latest
measuring technology in the field of earthing resistance measurements. By means of the
selectable limit input with visual and acoustical confirmation/error message and with the
code programmable and customer defined special functions, such as measuring voltage
20 V (for agricultural systems), earthing impedance R* (measuring frequency 55 Hz)
switched on or off, these instruments are individually programmable for use as a simple
meter as well as a high end fully automated measuring device.
