Resistance measurements (Q2w, 24w)
Select the INT, EXT or MAN start mode.
— Select the function Q2W or 24w.
= Select the correct range or the AUTO ranging mode.
Select the
HIGH RES mode or normal resolution mode.
— Connect the resistance to be measured to the correct input sockets.
Qaw
—0
(positive) and V-Q (negative)

— PROBE
Remarks
@ When only dashes are displayed (e.g. -_——.~— k Q) in the EXT or MAN start mode press START INT or
MAN,
@ Inthe Q4W function the 0 and the GUARD must be interconnected,
in the 24W function the 4-wire test lead can be used, For connector data, see fig. 15.
@ When very high resistances must be measured with high accuracy the input current has to be adjusted.
Refer to section 6.4.2. on page 45.

@ The relative reference mode can be used.
@ Use shielded cables in the high ranges to prevent errors in the measurements due to external influences.

In the 200M Q and 2000M &2 range the response time increases proportional to the measured value and
can be 22 seconds,
