1 Safety Regulations
This measuring device is only to be installed and operated by qualified
personnel and according to the technical data in compliance with the safety
precautions and regulations set forth below. Additionally, the use of this
equipment requires compliance with all legal and safety regulations
pertaining to each specific application. Similar regulations apply to the use of
accessories.
Operating electrical devices implies that parts of the device carry dangerous
voltages. Disregarding warning notices may lead to serious physical injury
and material damage.
It can be assumed that safe operation is no longer possible if the device
• shows visible damage,
• has been exposed to unfavourable conditions (e.g. storage beyond the
permissible climatic limits without adaptation to the ambient climate, dewing etc.) or
• has been exposed to major strain during transport (e.g. been dropped from
some height without visible external damage etc.).
No measurements must be performed on unprotected measuring circuits.
While a measurement is in progress no earth stake must be touched!
Qualified Personnel
are persons familiar with the setting up, installation, starting off and operation of the
device and possess a formal qualification required for such activities.

2 Description of instrument
This instrument has been manufactured complying with quality assurance system
DIN ISO 9001. The compliance with the actual EMC-regulations is documented by
the attached CE-sign.
This instrument is suited for measurements according to IEC 1024, ENV
61024, DIN VDE 0185 and ÖVE-E 49.
Application:
• Earth resistance measurements in different installations (e.g. high voltage
pylons, buildings, mobile communication stations, HF transmitters etc.)
• Monitoring and planing of lightning protection systems
• Resistance measurements with earth electrodes; no separation

connector cable!
Select function RA3-pole
Display is as shown below.
Connect test leads
Hint: Colour coded front plate and terminals provide appropriate connection.
Connect terminal E/C1 to earth electrode with short test lead (1,5 m).
Place 2 ground stakes. Minimum distance between earth electrode (E/C1),
probe (S/P2), and auxiliary earth (H/C2) is 20m!
Connect stakes with 25m and 50m wires to H/C2 and S/P2 as shown.
Press START
The ”active” symbol indicates that measurement is in progress.
Continuous measurement as long as START is pressed.
Symbol ” ” indicates completed measurement. The result is kept on the
display until a new measurement is started or the main switch is turned.
