8. While the instrument is measuring a
screen similar to the one beside
appears where the instrument's input
interfering voltage value is displayed.
When the message
do not disconnect or touch the test
leads
When starting measurement the input interfering voltage is measured at both
the volt and ampere circuit. Should it range between 3 V and 9 V, the
instrument carries out measurement and displays the symbol
uncertainty decline of the measurement (§ 9.1)
9. When the test is over, should the earth
resistance value be lower than the full
scale, the instrument emits a double
tone indicating the positive outcome of
the test and displays the resistance
measurement as well as the interfering
voltage value at the time of measuring
The resistance measurement is effected with 4-wire volt ampere method
without being affected by the resistance value of the cables. It is therefore not
necessary to effect compensation of cable resistance or of any extension
10. When the test is over, should the earth
resistance value be higher than the full
scale, the instrument emits a long tone
indicating the negative outcome of the
test and displays the screen beside
The measurements can be stored pressing the SAVE key twice (§ 5.1)
