CONTINUITY TEST
1) Connect red & black test leads to P + N terminals respectively.
2) Turn dial to low Ω (continuity setting). Display shows 'LOW Ω ' at top left.
3) Select: 'Auto', 'R+', 'R-', 'R+TIMER', 'R-TIMER'. By repeated pressing of
the key. See below for details of individual tests.
If using the timer function, set time using + keys
4) Connect the test leads to the conductors on which the continuity test is to
be carried out.
5) Press yellow key – The instrument performs the test
Auto: The instrument carries out 2 measurements. 1x positive polarity and
1 x negative polarity. The instrument displays an average reading of
the two measurements performed.
R+: The instrument carries out 1 measurement with a positive polarity. I.E.
Red test lead positive.
R-: The instrument carries out 1 measurement with a negative polarity.
I.E. Black test lead positive
R+TIMER: The instrument carries out 1 measurement with a positive polarity and
an adjustable duration of test. Min 3 seconds, Max 15 seconds. Use
+ to set test duration.
R-TIMER: The instrument carries out 1 measurement with a negative polarity and
an adjustable duration of test. Minimum of 3 seconds, Maximum of
15 seconds.
Use
+ to adjust time up and down respectively.
At the end of the test, if the resistance value is lower than 5
Ω
, the instrument
beeps twice, indicating low resistance. The resistance value is displayed on the
screen.
NB Cal & Low Ω is displayed in the top left of the screen if a lead compensation
value is stored; this value will be applied to any measurement made.
