LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship
under normal use and service. The warranty period is two years and begins on the date of
shipment. Parts, product repairs, and services are warranted for 90 days. This warranty
extends only to the original buyer or end-user customer of a Fluke authorized reseller,
and does not apply to fuses, disposable batteries, or to any product which, in Fluke's
opinion, has been misused, altered, neglected, contaminated, or damaged by accident or
abnormal conditions of operation or handling. Fluke warrants that software will operate
substantially in accordance with its functional specifications for 90 days and that it has
been properly recorded on non-defective media. Fluke does not warrant that software will
be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-
user customers only but have no authority to extend a greater or different warranty on
behalf of Fluke. Warranty support is available only if product is purchased through a Fluke
authorized sales outlet or Buyer has paid the applicable international price. Fluke re-
serves the right to invoice Buyer for importation costs of repair/replacement parts when
product purchased in one country is submitted for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price,
free of charge repair, or replacement of a defective product which is returned to a Fluke
authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center to obtain
return authorization information, then send the product to that service center, with a de-
scription of the difficulty, postage and insurance prepaid (FOB Destination). Fluke as-
sumes no risk for damage in transit. Following warranty repair, the product will be re-
turned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that failure
was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition
of operation or handling, including overvoltage failures caused by use outside the prod-
uct’s specified rating, or normal wear and tear of mechanical components, Fluke will pro-
vide an estimate of repair costs and obtain authorization before commencing the work.
Following repair, the product will be returned to the Buyer transportation prepaid and the
Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).
THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF
ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED
TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PAR-
TICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF
DATA, ARISING FROM ANY CAUSE OR THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty,
or exclusion or limitation of incidental or consequential damages, the limitations and ex-
clusions of this warranty may not apply to every buyer. If any provision of this Warranty is
held invalid or unenforceable by a court or other decision-maker of competent jurisdiction,
such holding will not affect the validity or enforceability of any other provision.

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.
Features
•Earth/ground resistance measurements in different installations (e.g.
high voltage pylons, buildings, electrical service grounding systems,
mobile communication stations, HF transmitters etc.)
•Monitoring and planning of lightning protection systems
•Resistance measurements with earth electrodes; no separation
Refer to Figure 1 and Table 1 for a complete list of features and functions.

Operating Instructions
RA2-pole, 3-pole Measurements
To make 2-pole or dead-earth measurements, connect a jumper between
terminals H/C2 and S/P2 with the supplied connector cable. Refer to Figures 3
and 4. Then follow steps 1 thru 4 except use only earth electrode and the
auxiliary earth electrode with minimum distance between them of 20 m.
ASelect function RA3-pole.
Display is as shown below.
BConnect test leads
Connect terminal E/C1 to the earth/ground system to be measured
with the supplied test lead and clip (1.5 m). Place 2 ground stakes in
earth/dirt. Minimum distance between earth electrode (E/C1), probe
(S/P2), and auxiliary earth (H/C2) should be at least 20 m!
Connect the stakes with the 25 m and 50 m cable reels to H/C2 and
S/P2 as shown below.
CPress START.
The “active” symbol indicates that a measurement is in progress. For
a continuous measurement keep START pressed.
DThe Symbol “9” indicates a completed measurement. The result is
kept on the display until a new measurement is started or the main
switch is turned.
