Safety Regulations
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.

Troubleshooting

Œ
External voltage (Uext) too high
If the external voltage applied to the instrument is too high, no
measurement can be started (see “Technical data” for Uext limit).
Hint: Reposition probe (S/P2) and restart measurement.
•
Auxiliary earth electrode resistance (R H) too high
If the auxiliary earth electrode resistance is too high it is not possible to
drive the current necessary for reliable measurements. The measurement
is blocked (see “Technical data” for Rh limit).
Hint: Check connection of test lead with terminal H/C2, check auxiliary earth
stake.
Ž
Probe resistance (Rs) too high
If the probe resistance is too high measurements are not reliable. The
measurement is blocked (see “Technical data” for Rs limit).
Hint: Check connection of test lead with terminal S/P2, check probe stake.
•
Weak batteries
If the batteries are weak the supply voltage may break down during
measurement. If there is enough energy to complete the measurement
”
” symbol is displayed - measuring results are valid. If not, a reset
occurs.
Hint: Replace batteries. Use 6 alkaline AA-type (LR6) batteries.
•
Is your R A measurement result reliable?
Probe S/P2 must be outside the potential gradient areas of E/C1 and H/C2
for accurate measurements. Normally a probe distance of more than 20m
is sufficient. However in some environmental conditions (depending mainly
on the soil resistivity) this may not suffice. To be sure reposition the probes
and take several measurements. If the readings are appr. the same your
measuring results are reliable, if not increase the probe distance.
