4 Operate the Continuity Null (F1) button, this will null out the lead resistance and the
indicated reading should go to zero.
5 Release the test button. Press the test button and ensure the display reads zero
before proceeding. While using the Continuity null function, “NULL
”
is displayed
on the LCD as indicated in Fig.13. The null value will be stored even if the instrument
is powered off. This memorized null value can be cancelled by disconnecting the
test leads and pushing the Continuity Null button (F1) with the test button pressed or
locked. When this is cancelled you will know because NULL OFF is displayed on the
LCD.
CAUTION - before taking any measurements always check the leads have been
zeroed.
6 Connect the test leads to the circuit whose resistance is required (see Fig.14 for a
typical connection arrangement), having first made sure
that the circuit is not live.
Note that “Live Circuit” warning will be displayed on the LCD if the circuit is live - but
check first anyway!
7 Press the test button and read the circuit resistance from the display. The reading
will have the test lead resistance already subtracted if the Continuity null function has
been used.
8 Note that if the circuit resistance is greater than 20Ω the instrument will autorange to
the 200Ω, if it is greater than 200Ω it will autorange to the 2000Ω range.
Note: If the reading is greater than 2000Ω the overange symbol ‘>’ will remain
displayed.
WARNING
The results of measurements can be adversely affected by impedances of
additional operating circuits connected in parallel or by transient currents.
