6. Tests, Resistance mode
Resistance mode measures the resistance of a unit under test in a forward current direction (unidirectional mode) or
forward and reverse direction (bidirectional mode). In manual start mode, the test will be carried out when the TEST
button is pressed. In auto start mode the DLRO2 will start the test automatically as soon as continuity is detected,
however it will not automatically start testing if continuity is established before the test mode is selected.
6.1 Auto-start, bidirectional / unidirectional resistance mode
1. Turn rotary switch to select either the auto-start,
bidirectional resistance mode position or auto-start,
unidirectional resistance mode position.
OR
Resistance test screen appears, ‘Auto-start, Bidirectional
Resistance Mode’ or ‘Auto-start, Unidirectional Resistance
Mode’ shows in secondary field for a short time then
disappears.
Note:
Soft key 1 toggles continuous / single test.
Soft keys 2 / 3 cycles through current ratings;
default is 2 A, selectable 1 A, 100 mA, 10 mA, 1 mA.
In bidirectional, soft key 4 toggles between ‘Display
previous 2 results’ and ‘Forward and reverse direction’.
2. Select test settings using the soft keys.
3. Connect C1-C2 and P1-P2 to the instrument and the unit
under test.
C and P indicators show red background with
for no
continuity or green background with
for good continuity.
When continuity is detected on both circuits, the C and
P indicators will both be greyed out and the test will start
automatically.
If required, to stop the test press the TEST button.
