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
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.
