Touch voltage U
B
 If only the measurement of U
B
, R
E
is selected, these values are measured with the
0.4 I
Δn
current without tripping the RCD. If the RCD trips during the measurement,
press ESC to go to the next measurements.
 Due to the specific character of the measurement (step increase of the I
A
current),
the measurement result for the tripping time t
Ai
in this mode may include a positive
error or the message may be displayed due to the RCD inertia. If the result is
outside the allowed range for a given RCD, repeat the measurement in the t
A
mode
(see section 3.5.2).
 Save the result in the memory (see section 4.1) or press the ESC button to display
the voltage only. The last measurement result is remembered until you press the
START button or change the rotary switch position.
Additional information displayed by the meter
Meter ready for measurement
Voltage on the meter L and N terminals is out of range for
which the measurement can be made.
The L and N conductors are switched (voltage between the
PE and N conductors).
Temperature inside the meter has exceeded the allowed
limit. The measurement is blocked.
RCD did not trip or tripped too late.
After the U
B
R
E
measurement, the t
A
measurement was
not performed because the R
E
and voltage values did not
allow generating the required current value.
Incorrect or unstable power grid frequency.
Measurement error – loss of voltage after the measure-
ment or RCD tripped during the U
B
or R
E
measurement.
Safe touch voltage is exceeded.
