Save the measurement to the meter memory using the icon. A detailed description
of memory management is contained in section 5.1.3.
The last measurement can be recalled using the icon.
 Measurements may be performed in the presence of interference current of a value
not exceeding 3 A RMS and frequency in accordance with the value set in sub-
menu Measurement settings (section 2.2.1 step ).
 Use N-1 clamps as signal transmitting clamps and C-3 clamps as receiving
clamps.
 If the current on measuring clamps is too low, the meter displays the following mes-
sage: The current measured by clamps is too low. Measurement is not possi-
ble!.
 Maximum interference current: 1 A.

R
E
>99.9Ω
Measuring range is exceeded.
Signal / noise ratio is too low (interfering signal too large).
Error due to the resistance of electrodes > 30 % (for cal-
culating uncertainty, measured values are taken into ac-
count).
Too small test current.
No continuity in the current clamps circuit.
