Note: If the START/STOP key was pressed and held, the instrument takes more
consecutive tests.
5. When a new value is acquired the instrument emits a short sound and calculates the
new average value.
6. Press DISP key to show how many measurements are in average value
DISP
calculation and the measuring mode.

7. Press CLR key if you want to cancel the medium value of the resistance
and the number of measurements which are included in the calculation.
Example: if the operator takes three consecutive measurements, the instrument displays
st
1 measurement:
main display = measured resistance value (Ex: 0.90Ω)
secondary display on the left-hand side = 001 (no. of measurements = 1
means that 1 earth measurement has been taken)
secondary display = average of the measurements taken (in case just one
measurement has been taken the medium value is equal to the measured
value, in this case 0.90Ω)
nd
2 measurement:
main display = measured resistance value (Ex: 0.96Ω)
secondary display = average of the measurements taken ((Val1+Val2)/no.
of measurements = (0.90+0.96)/2 = 0.93Ω)
rd
3 measurement:
main display = measured resistance value (Ex: 0.93Ω)
secondary display = average of the measurements taken ((Val1+Val2)/no.
of measurements = (0.90+0.96+0.93)/3 = 0.93Ω)
Note: Any test with result over 1999Ω is not inserted in the calculation of medium value.
st
Example: 1 measurement:
main display: 1,07Ω
secondary display: 1,07Ω
nd
2 measurement
main display: 4,15Ω
secondary display: 2,61Ω
rd
3 measurement (not inserted in the medium value)
main display: >1999Ω
secondary display: 2,61Ω
