Notes:
Consider displayed warnings before starting measurement!
For more information how to calibrate the test leads see

9.2.2.2 Auto-continuity test
In the auto continuity test mode up to 30 continuity tests can be performed and stored in
one step. Additional features are:
- Connection of test leads to a low resistance connections is detected and the
measurements starts/ stops automatically,
- Sound warnings are indicating the actual phase of the measurement.
- The autotest is useful if testing large machines with a lot of PE connection points.
- The user does not need to return to the instrument and pressing
START/STOP/SAVE keys for each individual measurement. The test can easily
be carried out by one person even if testing with long test leads on large
machines.
Continuity measurement procedure
Select the
CONTINUITY
function.
Set test
parameters.
Make sure that the test leads are calibrated. Calibrate them if necessary (See
chapter
9.2.2.3
Compensation of test leads resistance for more information).
Connect
test leads to S/C1 and C2 terminals on the instrument.
Press the
START
key for measurement. The instrument is monitoring for a low
resistance between the test leads is detected.
Connect
test leads to both ends of the first PE connection under test. The
instrument detects (double beep) the low resistance and starts first measurement.
After the timer elapse the instruments temporarily stores the first result. A sound
signal (short beeps) indicates that the first measurement is concluded and
temporarily stored. The results displayed in this phase will not be stored.
Disconnect
test leads and proceed to the next measuring point (no beep).
Connect
test leads to both ends of the second PE connection under test. The
instrument detects (double beep) the low resistance and starts second
measurement.
After the timer elapse the instruments temporarily stores the second result. A
sound signal (continuous short beeps) indicates that the second measurement is
concluded and temporarily stored. The results displayed in this phase will not be
stored.
